Nowhere was the emotion and religious symbolism more acute than in Misrata. The city suffered heavy losses resisting a siege by the army of Muammar Qadhafi. Local forces, which took credit for last month's capture of the ousted strongman that ended in his death, are pushing for a big say in the new Libya.
Men streamed away from dawn prayers at the imposing mosque in Misrata's Zorugh neighbourhood, preparing to feast on sheep slaughtered in a ritual inspired by Abraham's willingness to sacrifice his son to God.
They spoke of the special savour of a first Eid free of Gaddafi's personal rule, of embracing a new democracy but also of sorrow for loved ones killed in the war.
"We are happy," said Mohammed Bashir, a 40-year-old merchant in the prosperous suburb as he exchanged handshakes with friends and neighbours, all dressed in fresh robes and new clothes for Eid. "But we are crying for our children we lost in the war."
"This Eid is different we killed Qadhafi," laughed Ali Sheikh, 86, his English spiced with a rich Texan drawl acquired over decades working for American firms drilling for Libyan oil. "Now we're all going home to kill our lambs. "It's gonna be OK. We can fix this country real fast."
Ibrahim al-Assawi, 41, a university chemistry lecturer, said: "This Eid is a special Eid because Qadhafi is gone. So we ask God for our country to be better. We want the next government to be better. It can't be worse than Qadhafi."
Teacher Abdelsalam al-Madani, who at 40 was born two years after Colonel Qadhafi seized power, said simply: "This is a special Eid, because Eids before, there was no freedom."
