The protests began on 25 January 2011 when thousands of Egyptians gathered in the capital city Cairo after an internet campaign.
It was inspired by the protests in Tunisia in the same month.
The police used water cannon and tear gas to try to stop the protesters, and the government imposed a curfew - an order that means everyone has to be indoors after a certain time of day.
But the people ignored the government and even more demonstrations happened in the main cities of Egypt - Cairo, Alexandria, Suez and Ismailiya.
On 2 February, supporters of the government surged into Tahrir Square in Cairo and violent fighting broke out between them and the protesters.
Around 300 people were killed in the first 10 days of clashes, according to UN estimates.
On 11 February, the 18th day of protests, Egypt's Vice President Omar Suleiman announced on Egyptian TV that President Mubarak was stepping down.
