History
The mountains and foothills of the north have been settled since the Stone Age: Shanidar Cave, in the mountains of Erbil province, held Neanderthal burials tens of thousands of years old. Erbil, ancient Arbela, was an important Assyrian city with a temple of Ishtar on the mound that is now the citadel, and Alexander's victory over Darius III in 331 BC is also called the Battle of Arbela. The region later lay on the frontier between Rome and the Persians, and the Assyrian Church of the East spread through its villages.
In the Islamic period the Kurds were ruled by local dynasties and emirates. In the 12th and 13th centuries Erbil flourished under the atabeg Muzaffar al-Din Gökböri, who built its minaret. Under the Ottomans, Kurdish principalities — Soran at Rawanduz, Bahdinan at Amedi and Baban, whose prince founded Sulaymaniyah in 1784 — kept much autonomy until the 19th century.
After the First World War Britain added the region to the new state of Iraq, putting down revolts led by Sheikh Mahmud Barzanji in Sulaymaniyah in the 1920s. Mustafa Barzani led Kurdish uprisings from the 1940s onward. Under Saddam, the Anfal campaign of 1988 destroyed some 1,200 villages, and in 1988 a chemical attack on Halabja, near Sulaymaniyah, killed thousands in a day. After the 1991 uprising and a Western no-fly zone the Kurds gained self-government, recognised in Iraq's 2005 constitution. The region fought ISIS from 2014 and held an independence referendum in 2017, after which Baghdad took back Kirkuk and other disputed areas.
