CAIRO: Egyptians woke to a new dawn on Saturday after 30 years of autocratic rule under Hosni Mubarak.

As the muezzin’s call to prayer reverberated across Cairo, the sound of horns honking in jubilation grew louder after a night when millions celebrated the fall of the former president.

“The people overthrow the regime”. “The Revolution of the Youths forced Mubarak to leave”, said front-page headlines in semi-official al-Ahram newspaper.

A wave of people power has roared across the biggest Arab nation, just four weeks after Tunisians toppled their own ageing strongman. Now, across the Middle East and beyond, autocratic rulers are calculating their own chances of survival.

“The Jan. 25 Revolution won. Mubarak steps out and the army rules,” official newspaper Al-Gomhuria said.

Eighteen days of rallies on Cairo’s Tahrir, or Liberation, Square, resisting police assaults and a last-ditch charge by hardliners on camels, brought undreamt of success.

“We are finally going to get a government we choose,” said 29-year-old call-centre worker Rasha Abu Omar. “Perhaps we will finally get to have the better country we always dreamed of.”

Hours after word flashed out that Mubarak was stepping down and handing over to the army, it was not just Tahrir Square but, it seemed, every street and neighbourhood in Cairo, Alexandria and cities and towns across the country that were packed full.

Through the night, fireworks cracked, cars honked under swathes of red, white and black Egyptian flags, people hoisted their children above their heads. Some took souvenir snaps with smiling soldiers on their tanks on city streets.

All laughed and embraced in the hope of a new era.

Infectious People Power

Journalists long used to the sullen quiet of the police states that make up much of the Middle East felt the surging joy of the population around them as a palpable, physical sensation.

Relayed by satellite television channels and on Internet social networking sites, the euphoria in Egypt flashed around a region where autocrats hold sway from the Atlantic to the Gulf.

It was just eight weeks to the day since a young Tunisian vegetable seller, Mohamed Bouazizi, set himself alight outside a local government building in the provincial city of Sidi Bouzid, protesting in this way at his ill-treatment by police, who had taken away his livelihood, and at venal, oppressive government.

Four weeks later, Tunisian President Zine al-Abidine Ben Ali had been forced to flee the country when his generals told him they were not prepared to defend him against protesters.

Now Mubarak, an 82-year-old who when this year began seemed ready to establish a new dynasty on the Nile by handing over to his businessman son, sits, impotent, in the Egyptian Red Sea resort of Sharm el-Sheikh and his generals hold power in Cairo.

In Algiers, thousands of police in riot gear were braced for action to stop a planned demonstration there on Saturday from mimicking the uprising in Egypt. Officials have banned the opposition march, setting the stage for possible clashes.

“It’s going to be a great day for democracy in Algeria,” said Mohsen Belabes, a spokesman for the small RCD opposition party which is one of the organisers of the protest.

In Bahrain, the oil-rich Gulf kingdom, officials were handing out cash worth over $2,500 to every family, to appease them ahead of protests opposition groups plan for Monday.

In non-Arab Iran, leaders hailed the victory of the people over a leader seen in Tehran as a puppet of Washington and Israel. But the White House said a clampdown on media coverage of the events in Egypt showed that Iran’s Islamist rulers were “scared” of pro-democracy activists who have said they may renew the street protests that rocked Tehran in 2009.

“It’s broken a psychological barrier not just for North Africa but across the Middle East. I think you could see some contagion in terms of protests; Morocco, perhaps Jordan, Yemen,” said Anthony Skinner of political risk consultancy Maplecroft.

Beyond the Arab world, China — wary of any foreign upheavals that could reflect badly on its own authoritarian controls — gave its first reaction in the official China Daily.

“Social stability should be of overriding importance. Any political changes will be meaningless if the country falls prey to chaos in the end,” the English-language newspaper said.

The End, At Last

Mubarak’s end was, finally, swift, coming less than a day after he had stunned protesters by insisting he would not step down despite widespread expectations that he was about to do so.

It remains to be seen how the army will create democracy for the first time in a nation that traces its history back 7,000 years.

Vice President Omar Suleiman said a military council would run the country of 80 million for now. The council gave few details of what it said would be a “transitional phase” and gave no timetable for presidential or parliamentary elections.
