An internal conflict broke out between anti-communist Muslim guerrillas and the Afghan communist government. The rebellion grew all over Afghanistan. The war settled into a stalemate because the rebels usually eluded the Soviet's attacks.
The Soviet Union sent thousands of troops into Afghanistan. They were sent to stop the Afghan Civil War, and they took control over large cities like Kabul. It was the only time The Soviet Union invaded a country outside the Eastern Bloc
The People's Democratic Party of Afghanistan was founded in 1965. Soon after its foundation it split in 1967 and the two groups that emerged in Afghanistan were the Soviets and the Nationalists.
The withdrawal of the Soviets disrupted the country's population pattern and economics. There was a large economic decline under the Mujahideen and Taliban governments. The economy also declined when the Taliban banned the production of opium which was one of Afghanistan's most profitable markets.
Most people fled from the Afghan War to neighboring countries Pakistan and Iran. Many moved to escape being forced to enlist in the military. About 3.5 million went to Pakistan and 2 million fled to Iran.
