18 days in Tahrir Square: The protest in Egypt lasted 18 days in Tahrir square, located in downtown Cairo. This protest was the biggest one to occur as smaller protests before were shut down by the police. The huge turnout of people this time could be due to the people having access to information regarding information as to when and where protests would happen.
A man named Wael Ghonim had set up a Facebook page where he expressed his frustration against the government. Many people ended up following his page, also adding remarks of their own. Ghonim used social media to his advantage and spread information about protests to his huge following. They planned everything out and were able to keep it hidden from the government and police.
Once the protesting broke out in Tahrir Square they were met with police brutality. The police were armed with tear gas, water cannons, and guns. Around 800 people were killed in the conflict and this brought the attention of the media. As in Tunisia, the world criticized Mubarak's excessive hostility and was forced to resign.
