The Machine Breaks: Civil War 1975–1990

OPENING SCENE

Quick Recap: In Days 1 and 2 we saw how Lebanon was built — a confessional formula frozen to 1932 demographics — and how it prospered while accumulating structural pressure: Shia exclusion, a PLO army operating inside Lebanon, and a political system incapable of self-reform. By 1974, the pressure had reached a critical level.

Beirut, April 13, 1975. A Sunday morning. Pierre Gemayel, the founder of the Maronite Phalangist party, has been attending the dedication of a church in the Ain al-Rummaneh neighborhood in East Beirut. Outside, gunmen attack. Three of Gemayel's bodyguards are killed. Gemayel escapes unhurt.

Two hours later, a bus carrying Palestinian passengers passes through the same neighborhood on its return from a ceremony. Phalangist gunmen open fire. Twenty-seven people are killed. The bus continues rolling — no one is left to drive it.

That afternoon and evening, fighting spreads across Beirut. By nightfall, the Lebanese civil war has begun.

It will last fifteen years, kill 150,000 to 170,000 people, displace 800,000 more, and end with the country's infrastructure largely destroyed and the underlying political problems entirely unresolved.

Today's Core Question: Why did a country with a functioning economy and a formal peace agreement descend into fifteen years of multi-sided war — and what did the peace deal that ended it actually settle?
