When the Ba'ath Party took power in Iraq, the new government, in order to end the Kurdish revolt, granted the Kurds their own limited autonomy. However, for various reasons, including the pro-Iranian sympathies of some Kurds during the Iran–Iraq War in the 1980s, the regime implemented anti-Kurdish policies and a "de facto" civil war broke out. From March 29, 1987 until April 23, 1989, the infamous Al-Anfal campaign, a systematic genocide of the Kurdish people in Iraq, was launched. For this, Iraq was widely condemned by the international community, but was never seriously punished for oppressive measures, including the use of chemical weapons against the Kurds, which resulted in thousands of deaths.
