"Current history" redirects here. For the academic journal, see Current History
, in English-language historiography
, is a subset of modern history
that describes the historical period
from approximately 1945 to the present.
Contemporary history is either a subset of the late modern period
, or it is one of the three major subsets of modern history, alongside the early modern period
and the late modern period. The term contemporary history
has been in use at least since the early 19th century.
Contemporary history is politically
dominated by the Cold War
(1945–1991) between the United States and the Soviet Union
whose effects were felt across the world. The confrontation, which was mainly fought through proxy wars
and through intervention in the internal politics of smaller nations, ultimately ended with the dissolution of the Soviet Union
and Warsaw Pact
in 1991, following the Revolutions of 1989
. The latter stages and aftermath of the Cold War enabled the democratisation
of much of Europe, Africa, and Latin America. In the Middle East, the period after 1945 was dominated by conflict involving the new state of Israel
and the rise of petroleum politics
, as well as the growth of Islamism
after the 1980s. The first supranational organisations of government, such as the United Nations and European Union
, emerged during the period after 1945, while the European colonial empires
in Africa and Asia collapsed, gone by 1975. Countercultures
rose and the sexual revolution
relations in western countries between the 1960s and 1980s, epitomised by the Protests of 1968
. Living standards rose sharply across the developed world
because of the post-war economic boom
, whereby such major economies as Japan and West Germany
emerged. The culture of the United States
, especially consumerism
, spread widely. By the 1960s, many western countries had begun deindustrializing
; in their place, globalization
led to the emergence of new industrial centres, such as Japan
, South Korea
and later China
, which exported consumer goods to developed countries
In 2020, an outbreak of the COVID-19
disease, first documented in late 2019 in Wuhan
, spread to other countries becoming a global pandemic
, which caused a major socio-economic disruption all over the world. Many countries ordered mandatory lockdowns
on movement and closures of non-essential businesses. The pandemic was described by some commentators as the most important global event of the 21st century
, as well as the greatest crisis of modern times.
In the first half of the 20th century, the world saw a series of great conflagrations, World War I
and World War II
. Near the end of the first world war, there were a series of Russian Revolutions
and a Russian Civil War
. In between the world wars, the 1920s saw a great rise in prosperity where much of the world saw progress and new technology, but this was soon ended by the Great Depression
. During this time, the League of Nations
was formed to deal with global issues, but failed to garner enough support by the leading powers, and a series of crises once again led the world into another epoch of violence.
The Cold War began in 1947 and lasted until 1991. The Space Age
was concurrent with this time, encompassing the activities related to the Space Race
, space exploration
, space technology, and the cultural developments influenced by these events. Pax Americana
is an appellation applied to the historical concept of relative liberal peace in the Western world, resulting from the preponderance of power enjoyed by the United States of America after the end of World War II in 1945.
The post-1945 world experienced the establishment of many new states
. Throughout the post-1945 period, the Cold War was expressed through military coalitions, espionage, weapons development, invasions, propaganda, and competitive technological development. The Soviet Union created the Eastern Bloc
of countries that it occupied, annexing some as Soviet Socialist Republics
and maintaining others as satellite states
that would later form the Warsaw Pact
. The United States and various Western European countries began a Containment
policy for communism
and forged alliances to this end, including NATO
. The conflict included defense spending, a conventional
and nuclear arms race
, and various proxy wars
; the two superpowers never fought one another directly.
Information age and computers
A Visualization of the various routes through a portion of the Internet. Partial map of the Internet based in 2005.
The Information Age
or Information Era, also commonly known as the Age of the Computer, is an idea that the current age will be characterized by the ability of individuals to transfer information freely, and to have instant access to knowledge that would have been difficult or impossible to find previously. The idea is heavily linked to the concept of a Digital Age
or Digital Revolution
, and carries the ramifications of a shift from traditional industry that the Industrial Revolution brought through industrialization, to an economy based around the manipulation of information. The period is generally said to have begun in the latter half of the 20th century, though the particular date varies. The term began its use around the late 1980s and early 1990s, and has been used up to the present with the availability of the Internet.
During the late 1990s, both Internet directories
and search engines
(both founded 1995) were the respective industry leaders. By late 2001, the directory model had begun to give way to search engines, tracking the rise of Google (founded 1998), which had developed new approaches to relevancy ranking
. Directory features, while still commonly available, became after-thoughts to search engines. Database size, which had been a significant marketing feature through the early 2000s (decade), was similarly displaced by emphasis on relevancy ranking, the methods by which search engines attempt to sort the best results first.
" is characterized as facilitating communication, information sharing
, User-centered design
on the World Wide Web
. It has led to the development and evolution of web-based communities, hosted services
, and web applications
. Examples include social-networking sites
, video-sharing sites
, blogs, mashups
. Social networking
emerged in the early 21st century as a popular social communication, largely replacing much of the function of email, message boards
and instant messaging
services. Twitter, Facebook, and YouTube are all major examples of social websites that gained widespread popularity. The information distribution continued into the early 21st century with mobile interaction
and Internet access
growing massively in the early 21st century. By the 2010s, a majority of people in the developed world had Internet access and a majority of people worldwide had a mobile phone.
Marking the rise of mobile computing
, worldwide sales of personal computers fall 14% during the first quarter of 2013. The Semantic Web
(dubbed, "Web 3.0
") begins the inclusion of semantic
content in web pages, converting the current web dominated by unstructured and semi-structured documents into a "web of data".
Late contemporary times
Terrorism and warfare
The September 11 attacks
– which were described as a "watershed moment" of contemporary history – were a series of coordinated suicide attacks
upon the United States on 11 September 2001. On that morning, 19 Al-Qaeda terrorists hijacked
four commercial passenger jet airliners
The hijackers intentionally crashed two of the airliners into the Twin Towers of the World Trade Center
in New York City, killing everyone on board and many others working in the buildings. Both buildings collapsed within two hours, destroying nearby buildings and damaging others. The hijackers crashed a third airliner into the Pentagon
in Arlington, Virginia
, just outside Washington, D.C. The fourth plane crashed into a field near Shanksville
in rural Somerset County, Pennsylvania
, after some of its passengers and flight crew attempted to retake control of the plane, which the hijackers had redirected toward Washington, D.C. Major terrorist events after the 11 September 2001 Attacks include the Moscow Theatre Siege
, the 2003 Istanbul bombings
, the Madrid train bombings
, the Beslan school hostage crisis
, the 2005 London bombings
, the October 2005 New Delhi bombings
, and the 2008 Mumbai Hotel Siege
The United States responded to the 11 September 2001 attacks by launching a "Global War on Terrorism", invading Afghanistan
to depose the Taliban
, who had harbored al-Qaeda terrorists, and enacting the Patriot Act
. Many other countries also strengthened their anti-terrorism legislation and expanded law enforcement powers. The 'Global War on Terrorism' is the military, political, legal and ideological conflict against Islamic terrorism
and Islamic militants
since the 2001 attacks.
The War in Afghanistan
began in late 2001 and was launched by the United States with the United Kingdom, and NATO
-led, UN authorized ISAF
in response to the 11 September attacks. The aim of the invasion was to find the whereabouts of Osama bin Laden
and other high-ranking al-Qaeda members and put them on trial, to destroy the whole organization of al-Qaeda
, and to remove the Taliban
regime which supported and gave safe harbor to al-Qaeda. The Bush administration policy
and the Bush Doctrine
stated forces would not distinguish between terrorist organizations and nations or governments that harbor them. Two military operations in Afghanistan are fighting for control over the country. Operation Enduring Freedom
(OEF) is a United States combat operation involving some coalition partners and operating primarily in the eastern and southern parts of the country along the Pakistan
border. The second operation is the International Security Assistance Force
(ISAF), which was established by the UN Security Council
at the end of 2001 to secure Kabul
and the surrounding areas. NATO assumed control of ISAF in 2003.
The multinational infantry actions, with additional ground forces supplied by the Afghan Northern Alliance
, and aerial bombing
campaign removed the Taliban from power, but Taliban forces have since regained some strength.
The war has been less successful in achieving the goal of restricting al-Qaeda's movement than anticipated.
Since 2006, Afghanistan has seen threats to its stability from increased Taliban-led insurgent
activity, record-high levels of illegal drug production,
and a fragile government with limited control outside of Kabul
At the end of 2008, the war had been unsuccessful in capturing Osama bin Laden
and tensions have grown between the United States and Pakistan due to incidents of Taliban fighters crossing the Pakistan border while being pursued by coalition troops.
The Second Gulf War
began in March 2003 with the invasion of Iraq
by a multinational force
The invasion of Iraq led to an occupation
and the eventual capture of Saddam Hussein
, who was later executed
by the Iraqi Government. Violence against coalition forces and among various sectarian groups soon led to asymmetric warfare
with the Iraqi insurgency
, strife between many Sunni
Iraqi groups, and al-Qaeda operations in Iraq
. Evidence of war crimes
committed and sanctioned
by the United States Department of Justice
created controversy globally, and helped dispel the notion of the United States as a liberating force in the War of Terror.
Member nations of the Coalition withdrew their forces as public opinion favoring troop withdrawals increased and as Iraqi forces began to take responsibility for security.
In late 2008, the U.S. and Iraqi governments approved a Status of Forces Agreement
effective through to the end of 2011.
The Iraqi Parliament also ratified a Strategic Framework Agreement with the U.S.,
aimed at ensuring international cooperation in constitutional rights, threat deterrence, education,
energy development, and other areas.
In 2009, U.S. President Barack Obama
announced an 18-month withdrawal window for "combat forces".
The Obama administration
has renamed the War on Terror as the "Overseas Contingency Operation
Its objectives are to protect US citizens and business interests worldwide, break up terrorist cells in the US, and disrupt al-Qaeda and affiliated groups.
The administration has re-focused US involvement in the conflict on the withdrawal of its troops from Iraq, the closing of Guantanamo Bay detention camp
, and the surge in Afghanistan
. Using information obtained from Khalid Shaikh Mohammed
in 2007, the name and whereabouts of one of Bin Laden's couriers, Abu Ahmed al-Kuwaiti
, was learned, and the courier eventually led U.S. intelligence to the location of Osama bin Laden, which was located in a large compound
, Pakistan, a suburban area 35 miles from Islamabad
On 1 May 2011, he was killed
and the papers and computer drives and disks from the compound were seized. In 2011 Europe, the former Bosnian Serb Army
commander Ratko Mladić
, wanted for genocide
, war crimes
and crimes against humanity
, is arrested on 26 May in Serbia by the Military Security Agency
In 2011, the United States formally declared an end
to the Iraq War
The Arab Spring
began in earnest in 2010 with anti-government protests in the Muslim world
, but quickly escalated to full-scale military conflicts in countries like Syria
, and Yemen
and also gave the opportunity for the emergence of various militant groups including the Islamic State
(IS). The IS was able to take advantage of social media platforms including Twitter to recruit foreign fighters from around the world and seized significant portions of territory in Iraq
, and the Sinai Peninsula
from 2013 and ongoing. On the other hand, some violent militant organizations were able to negotiate peace with governments including the Moro Islamic Liberation Front
in the Philippines
in 2014. The presence of IS and the stalemate in the Syrian Civil War
created a migration of refugees to Europe
and also galvanized and encouraged high-profile terrorism attacks and armed conflicts around the world, such as the November 2015 Paris attacks
and the Battle of Marawi
in the Philippines in 2017. In 2014, the United States decided to intervene
against the Islamic State in Iraq
, with most IS fighters being driven out by the end of 2018. Russia and Iran
also jointly launched a campaign
against IS in Syria, in support of Syrian President Bashar al-Assad
, coming at odds with United States aims.
In the beginning of the 2000s (decade), there was a global rise in prices in commodities
, marking an end to the commodities recession of 1980–2000
. The US mortgage-backed securities, which had risks that were hard to assess, were marketed around the world and a broad based credit boom fed a global speculative bubble in real estate and equities. The financial situation was also affected by a sharp increase in oil and food prices
. The collapse of the American housing bubble
caused the values of securities
tied to real estate pricing
to plummet thereafter, damaging financial institutions.
The late-2000s recession
, a severe economic recession
which began in the United States in 2007,
was sparked by the outbreak of a modern financial crisis
The modern financial crisis was linked to earlier lending practices by financial institutions and the trend of securitization
of American real estate mortgages.
The emergence of Sub-prime loan losses exposed other risky loans and over-inflated asset prices.

From late 2009 European sovereign-debt crisis
, fears of a sovereign debt crisis developed among investors concerning rising government debt levels across the globe together with a wave of downgrading of government debt of certain European states. Concerns intensified early 2010 and thereafter making it difficult or impossible for sovereigns to re-finance their debts. On 9 May 2010, Europe's Finance Ministers approved a rescue package worth €750 billion aimed at ensuring financial stability across Europe. The European Financial Stability Facility
(EFSF) was a special purpose vehicle financed by members of the eurozone to combat the European sovereign debt crisis. In October 2011 eurozone leaders agreed on another package of measures designed to prevent the collapse of member economies. The three most affected countries, Greece, Ireland and Portugal, collectively account for six percent of eurozone's gross domestic product (GDP). In 2012, Eurozone
finance ministers reached an agreement on a second €130-billion Greek bailout. In 2013, the European Union agreed to a €10 billion economic bailout
Present and future
The third millennium is the third period of one thousand years. As this millennium is in progress, only its first decade, the 2000s (decade), can be the subject of the conventional historian's attention. The remaining part of the 21st century and longer-term trends are researched by futures studies
, an approach that uses various models and several methods (such as "forecasting
" and "backcasting
"). Ever since the invention of history, people have searched for "lessons" that might be drawn from its study, on the principle that to understand the past is potentially to control the future
A famous quote by George Santayana
has it that "Those who cannot remember the past are condemned to repeat it." Arnold J. Toynbee
, in his monumental Study of History
, sought regularities in the rise and fall of civilizations
In a more popular vein, Will and Ariel Durant
devoted a 1968 book, The Lessons of History
, to a discussion of "events and comments that might illuminate present affairs, future possibilities... and the conduct of states."
Discussions of history's lessons often tend to an excessive focus on historic detail or, conversely, on sweeping historiographic
Future Studies takes as one of its important attributes (epistemological
starting points) the ongoing effort to analyze alternative futures. This effort includes collecting quantitative and qualitative data about the possibility, probability, and desirability of change. The plurality of the term "futures" in futurology denotes the rich variety of alternative futures, including the subset of preferable futures (normative futures), that can be studied.
Practitioners of the discipline previously concentrated on extrapolating
, economic or social trends
, or on attempting to predict
future trends, but more recently they have started to examine social systems
and to build scenarios
, question the worldviews behind such scenarios via the causal layered analysis
method (and others) create preferred visions of the future, and use backcasting to derive alternative implementation strategies. Apart from extrapolation and scenarios, many dozens of methods and techniques are used in futures research.
At the end of the 20th century, the world was at a major crossroads. Throughout the century, more technological advances had been made than in all of preceding history. Computers, the Internet, and other modern technology
radically altered daily lives. Increased globalization
, specifically Americanization
, had occurred. While not necessarily a threat, it has sparked anti-Western and anti-American
sentiment in parts of the developing world, especially the Middle East. The English language has become a leading global language
, with people who did not speak it becoming increasingly disadvantaged.
A trend connecting economic and political events in North America, Asia, and the Middle East is the rapidly increasing demand for fossil fuels, which, along with fewer new petroleum finds, greater extraction costs (see peak oil
), and political turmoil, saw the price of gas and oil soar ~500% between 2000 and 2005. In some places, especially in Europe, gas could be $5 a gallon, depending on the currency. Less influential, but omnipresent, is the debate on Turkey's participation in the European Union
. New urbanism
and urban revival continue to be forces in urban planning in the United States.
However, evidence shows that growth of American suburbs still outpaces urban growth.
Challenges and problems
In the contemporary era, several issues are faced in the world.
First of all, wealth is concentrated among the G8
and Western industrialized nations
, along with several Asian nations and OPEC
countries. The richest 1% of adults alone owned 40% of global assets in the year 2000 and that the richest 10% of adults accounted for 85% of the world total.
The bottom half of the world adult population owned barely 1% of global wealth.
Another study found that the richest 2% own more than half of global household assets
Despite this, the distribution has been changing quite rapidly in the direction of greater concentration of wealth.
It usually is impossible to connect specific weather events to human impact on the world. Instead, such impact is expected to cause changes in the overall distribution and intensity of weather events, such as changes to the frequency and intensity of heavy precipitation. Broader effects are expected to include glacial retreat
, Arctic shrinkage
, and worldwide sea level rise
. Other effects may include changes in crop yields
, addition of new trade routes,
and changes in the range of disease vectors
. Until 2009, the Arctic Northwest Passage pack ice
prevented regular marine shipping
throughout most of the year in this area, but climate change has reduced the pack ice, and this Arctic shrinkage
made the waterways more navigable.
Various emerging technologies
, the recent developments and convergences in various fields of technology, hold possible future impacts. Emerging technologies
cover various cutting-edge developments in the emergence and convergence of technology, including transportation, information technology, biotechnology
and applied mechanics
, and material science
. Their status and possible effects involve controversy over the degree of social impact or the viability of the technologies. Though, these represent new and significant developments within a field; converging technologies represent previously distinct fields which are in some way moving towards stronger inter-connection and similar goals.
NASA announced in 2011 that its Mars Reconnaissance Orbiter
captured photographic evidence of possible liquid water on Mars during warm seasons. On 6 August 2012, the Mars Science Laboratory Curiosity
, the most elaborate Martian exploration vehicle to date, landed on Mars. After the WMAP
observations of the cosmic microwave background
, information was released in 2011 of the work done by the Planck Surveyor
, estimating the age of the Universe to 13.8 billion years old (a 100 million years older than previously thought). Another technological advancement came in 2012 with European physicists statistically demonstrating the existence of the Higgs boson
