He was deposed in 1973 by his cousin Mohammed Daoud, who proclaimed a republic. Daoud was killed in a 1978 coup, and Noor Taraki took power, setting up a Marxist regime. He, in turn, was executed in Sept. 1979, and Hafizullah Amin became president. Amin was killed in Dec. 1979, as the Soviets launched a full-scale invasion of Afghanistan and installed Babrak Karmal as president. The U.S. Responds to the September 11, 2001, Terrorist Attacks

On Oct. 7, after the Taliban repeatedly and defiantly refused to turn over Bin Laden, the U.S. and its allies began daily air strikes against Afghan military installations and terrorist training camps. Five weeks later, with the help of U.S. air support, the Northern Alliance managed with breathtaking speed to take the key cities of Mazar-i-Sharif and Kabul, the capital. On Dec. 7, the Taliban regime collapsed entirely when its troops fled their last stronghold, Kandahar. However, al-Qaeda members and other mujahideen from various parts of the Islamic world who had earlier fought alongside the Taliban persisted in pockets of fierce resistance, forcing U.S. and allied troops to maintain a presence in Afghanistan. Osama bin Laden and Taliban leader Mullah Muhammad Omar remained at large.
