Here are some key events from more than four years of turmoil and transition in Egypt:
— Feb. 11, 2011: Autocrat Hosni Mubarak steps down after 18 days of nationwide protests against his nearly 30-year rule. The military takes over, dissolving parliament and suspending the constitution after the uprising leaves hundreds of protesters dead in clashes with security forces.
— Nov. 28, 2011 – Feb. 15, 2012: The Muslim Brotherhood wins nearly half the seats in multi-stage elections for the first post-Mubarak parliament, while ultraconservative Salafi Islamists take another quarter. The remainder goes to liberal, independent and secular politicians.
