“The armed forces have made over the past months strenuous efforts, directly and indirectly, to contain the situation and conduct internal and national reconciliation among all political forces, including the institution of the presidency, since November 2012,” el-Sissi said. He said that “all political forces responded, but it was turned down by the presidency in the last moments.”

El-Sissi said the head of the country’s Supreme Constitutional Court, Adly Mansour, 67, would become the country’s acting president and would take the oath of office Thursday. He said Mansour would have the right to rule by decree until a new Parliament was seated. El-Sissi also called for Mansour to set presidential elections soon.

Mansour has been the deputy head of the court since 1992. He’ll retain his court position while serving as president.

The military’s announcement, which came at 9:20 p.m. after a day of tension as people waited to hear what the country’s generals had decided, brought to an end the first democratically elected administration in Egypt’s history. It marked another in a seemingly unending string of tumultuous events in the more than two years since Hosni Mubarak was forced to resign.

Morsi had said he would not step down and was unwavering to the end. In his last speech as president, he at one point yelled, “I am the president of Egypt.”

After seeing their fortunes dashed after a year of triumph, Morsi supporters lashed out. In Rabaa, McClatchy reporters witnessed Morsi supporters brutally beat a man after he identified himself as a journalist. “You are responsible for this!” one man yelled as he struck the 32-year-old man.

Throughout Cairo it was hard at times to differentiate the sound of people celebrating by launching fireworks from those shooting in the air, promising retribution.

Their reactions portended of instability here, despite el-Sissi’s plea that Egyptians “steer away from violence.” For some of Morsi’s supporters, an Islamic vision for the region was at stake.

The turn of events was a dramatic setback for the Brotherhood, which had been outlawed for much of its eight-decade history before the toppling in 2011 – under similar circumstances – of Mubarak.

Morsi was the first Brotherhood official to take power in an Arab country, and his removal from office could only be seen as a setback for an organization that only months ago was considered the premier political group in Egypt.

While the crowds in Cairo’s streets erupted in jubilation, some of the leaders of the 2011 demonstrations that led to Mubarak’s resignation voiced concern about the direction of events.

“If the military helps in ousting Morsi, I hope they won’t have a direct role as they did before,” said Ahmed Maher, who leads the April 6 Youth Movement and was a key organizer of the anti-Mubarak demonstrations that began on Jan. 25, 2011.

“I am afraid that the January 25 revolution would be forgotten,” he said. “If the upcoming period is not managed well, the remnants could come back.”

Maher’s sentiment captures the contradictions that plague the movement that forced Morsi from office. Morsi, however unpopular he was, was democratically elected, and there were no mechanisms in the country’s constitution that allowed for the military to intervene the way it has. Egypt has no vice president and there was no agreement among the opposition over the role of the military or who should replace Morsi.

In December, a constitutional committee dominated by the Brotherhood hastily passed a constitution that required a two-thirds vote of Parliament to remove the president. But the country’s court had ordered the Islamist-dominated Parliament dissolved, and with promised parliamentary elections never scheduled, Morsi gave himself legislative powers.

While Morsi’s rule was striking for its administrative incompetence, the army’s record during the 18 months it ruled between Mubarak’s resignation and Morsi’s inauguration wasn’t much better. During that time, the country’s economy flattened, the government carried out virginity tests on female protesters and raided 17 democracy promotion organizations, leading to the arrest of 43 people, including 16 Americans.

“They should force Morsi to leave and then leave themselves because they failed in managing the country,” Maher said.

Morsi’s 368 days in office were the only period since 1952 that Egypt’s top leader wasn’t a member of the military or a retired military officer.
