Hazem is a 10-year-old boy who lives in Cairo, the capital city of Egypt.
In January 2011 Hazem joined thousands of other Egyptians to protest at the way their country was being run.
The protesters went to Cairo's main square, Tahrir Square, and refused to leave until the country's leader, President Hosni Mubarak, gave up power.
After 18 days of protests, in which hundreds of people died and many more were injured, the protestors were successful and the president stepped down.
Young people played a key role in the revolution. Many were involved in inspiring and organising the demonstrations, others went along to show their support.
In this video broadcast on Newsround Hazem talks about what it was like during the massive anti-government protests in Tahrir Square.
A six minute Schools World Service version of the video is also available.
