Four years have passed since thousands of protesters took to the streets calling for change, after decades of stagnant street activity in Egypt. The protests soon snowballed into an uprising which toppled the regime of former President Hosni Mubarak.

Three anniversaries to the January 25 uprising have passed. Each anniversary was under a distinct rule; the Supreme Council of the Armed Forces (SCAF), Muslim Brotherhood leader Mohamed Mursi, and the military-installed regime headed by interim President Adli Mansour, respectively.

Each anniversary saw a different outcome in the demands of demonstrators, the way demonstrations were handled, and the aftermath it produced. The different results were not only due to the different regimes that ruled during each year, but also due to the different circumstances that surrounded the anniversaries.

A quick look at the tolls of deaths, injuries and arrests shows the three figures increased by the year.

No protesters were reported arrested in 2012, when security forces were nearly not present during the demonstrations. Those arrested following the 2013 and the 2014 anniversaries, however, faced exceptionally harsh detention conditions, with sexual assault and torture against detainees reported in both years, especially in 2014.

2015 marks the first anniversary of the uprising under the rule of former army general Abdel Fattah al-Sisi. It is also the first year to witness the acquittal of Mubarak and his Interior Minister of the charge of murdering the protesters killed in 2011.
