The Muslim Brotherhood,  the outlawed Islamist movement that until 18 days ago was considered  Egypt’s only viable opposition, said it was merely a supporting player  in the revolt.        
 “We participated with everyone else and did not lead this or raise  Islamic slogans so that it can be the revolution of everyone,” said  Mohamed Saad el-Katatni, a spokesman for the Brotherhood. “This is a  revolution for all Egyptians; there is no room for a single group’s  slogans, not the Brotherhood’s or anybody else.”        
 The Brotherhood has said it will not field a candidate for president or  seek a parliamentary majority in the expected elections.        
 The Mubarak era ended without any of the stability and predictability  that were the hallmarks of his tenure. Western and Egyptian officials  had expected Mr. Mubarak to leave office on Thursday and irrevocably  delegate his authority to Vice President Omar Suleiman, finishing the last six months of his term with at least his presidential title intact.        
 But whether because of pride or stubbornness, Mr. Mubarak instead spoke  once again as the unbowed father of the nation, barely alluding to a  vague “delegation” of authority.        
 The resulting disappointment enraged the Egyptian public, sent a million  people into the streets of Cairo on Friday morning and put in motion an  unceremonious retreat at the behest of the military he had commanded  for so long.        
 “Taking into consideration the difficult circumstances the country is  going through, President Mohammed Hosni Mubarak has decided to leave the  post of president of the republic and has tasked the Supreme Council of  the Armed Forces to manage the state’s affairs,” Mr. Suleiman said in a  brief televised statement.        
 It is now not clear what role Mr. Suleiman, whose credibility plummeted  over the past week as he stood by Mr. Mubarak and even questioned  Egypt’s readiness for democracy, will have in the new government.         
 The transfer of power leaves the Egyptian military in charge of this  nation, facing insistent calls for fundamental democratic change and  open elections. Hours before Mr. Suleiman announced Mr. Mubarak’s exit,  the military had signaled its takeover with a communiqué that appeared  to declare its solidarity with the protesters.        
 Read on state television by an army spokesman, the communiqué declared  that the military — not Mr. Mubarak, Mr. Suleiman or any other civilian  authority — would ensure the amendment of the Constitution to “conduct  free and fair presidential elections.”        
 “The armed forces are committed to sponsor the legitimate demands of the  people,” the statement declared, and the military promised to ensure  the fulfillment of its promises “within defined time frames” until  authority could be passed to a “free democratic community that the  people aspire to.”        
 It pledged to remove the reviled emergency law, which allows the  government to detain anyone without charges or trial, “as soon as the  current circumstances are over” and further promised immunity from  prosecution for the protesters, whom it called “the honest people who  refused the corruption and demanded reforms.”        
 Egyptians ignored the communiqué, as they have most official  pronouncements of the Mubarak government, until the president’s  resignation was announced. Then they hugged, kissed and cheered the  soldiers, lifting children on tanks to get their pictures taken. “The  people and the army are one hand,” they chanted.        
 Whether the military will subordinate itself to a civilian democracy or  install a new military dictator will be impossible to know for months.  Military leaders will inevitably face pressure to deliver the genuine  transition that protesters did not trust Mr. Mubarak to give them.
