Answer: Please Note that this is what I believe the answers are:
President Hosni Mubarak
Tahrir Square (Martyr Square)
Military
Step-by-step explanation:
These are the exact timeline from what happened in Egypt in the Arab Spring. Mubarak was an autocratic dictator for three decades prior to the Spring. Tahrir Square, also known as Martyr Square, is where the first gathering of protestors began protesting against Mubarak regime. The military part is the confusing part as its a half assumption. Here is why I say it's the military, the military forced him to transfer power to the Supreme Council of the Armed Forces.
