March 19, 2011: Egyptians cast their first free vote on constitutional amendments sponsored by the ruling military, which set a timeline for the country's transition to democracy. The military and Muslim Brotherhood rallied for a "yes" vote that passed easily against the largely secular and liberal opposition's "no" vote that would have paved the way for the constitution to be written sooner.
Nov. 28, 2011: Voting begins in Egypt's first parliamentary elections since Mubarak's ouster. It concludes in January with nearly half the seats won by the previously banned Muslim Brotherhood and a surprising win of a quarter of seats to the ultraconservative Salafi party.
Jan. 29, 2012: Multi-stage voting begins for Egypt's upper house of parliament, known as the Shura Council. A largely advisory body, the elections see a low voter turnout. Voting ends in late February with the Brotherhood winning nearly 60 percent of elected seats.
April 20, 2012: The presidential campaign officially begins.
May 23-24, 2012: A first round of nationwide voting on about a dozen candidates determines that the Muslim Brotherhood's candidate Mohammed Morsi and former Air Force general Ahmed Shafiq, the last prime minister under Mubarak, will face each other in a runoff.
June 14, 2012: The Supreme Constitutional Court rules to dissolve the lower house of parliament on grounds that a third of the chamber's members were elected illegally. The military swiftly closes down parliament. The upper chamber, which was also elected under the law the constitutional court ruled as illegal, is not dissolved, but is separately under review.
June 16-17, 2012: Egyptians vote in the runoff between Morsi and Shafiq. The military generals issue a "constitutional declaration" giving them sweeping authority to maintain their grip on power and limit the powers of the president.
June 24, 2012: Election officials declare Morsi the winner of Egypt's first free election, with 51.7 percent of the vote.
Aug. 12, 2012: Morsi cancels the generals' declaration that gave them lawmaking powers in the absence of parliament. He retires the head of the military council and the army's chief of staff after unidentified militants attack soldiers in North Sinai, killing 16.
Dec. 1, 2012: Morsi defies massive street protests against temporary power-grabbing decrees that gave the Islamist-led panel writing the constitution and the upper house of parliament immunity from judicial oversight just days ahead of a court decision that could have dissolved the bodies. Instead, he sets the referendum dates for the disputed charter for Dec. 15. and Dec. 22.
Dec. 15, 2012: Voters cast ballots in the first leg of the constitutional referendum, despite a boycott by thousands of judges protesting Morsi's decree. Unofficial results show that a majority voted "yes" for the draft constitution.
Dec. 22, 2012: Seventeen remaining provinces cast their ballots in the second round. The final tally shows the constitution was approved by nearly 64 percent of voters. But the opposition says just under a third of eligible voters took part in the referendum and many overseeing judges boycotted the vote, undermining charter's legitimacy.
Feb. 22, 2013: Egypt's president called for multi-stage parliamentary elections beginning in April.
