Al-Anfal Campaign
The most violent phase of the conflict between the Kurds and Iraqi Ba'athist regime was the Al-Anfal Campaign of the Iraqi Army against the Kurdish minority, which took place between 1986–1988 and included the Halabja chemical attack. The Al-Anfal campaign ended in 1988 with an agreement of amnesty between the two belligerents. No permanent gains were made by the Kurds.
