Timeline: Hosni Mubarak, Egypt’s President for Three Decades, Resigns

One of the Arab world’s longest-serving leaders, Egypt’s President Hosni Mubarak, stepped down Friday after 18 days of protests that continued to gain steam until the opposition’s No. 1 demand — his departure — was met.

The 82-year-old leader’s announcement came a day after he ceded some authorities over to Vice President Omar Suleiman, which did little to quell the protests that had taken hold around the country.

Economic problems, including high inflation, low wages and job losses, spurred the discontent in Egypt, which evolved into full-scale revolution earlier this year. On Jan. 25, anti-government protests began to spread across Egypt, partly inspired by mass demonstrations in Tunisia that ousted President Zine El Abidine Ben Ali and energized by social media services.

In response to the uprising, Mubarak said on Feb. 1 he would not run for a sixth term and had no intention of his son Gamal succeeding him. But the demonstrators, involving older activists, doctors, striking workers and youth, continued to press for his leaving office, planting themselves in Cairo’s Tahrir Square and crowding the entrance to Parliament, until he acquiesced on Feb. 11.

Suleiman delivered the one-line message on state television while Mubarak was believed to be in the Egyptian resort of Sharm el-Sheikh with his family. The crowds in Tahrir Square went wild at the news, waving Egyptian flags and chanting “Egypt is free.”

Mubarak had a background of formal military training before becoming president for 30 years.
