In short
Who colonized Iraq?
Britain. After Ottoman defeat in 1918, Britain took Iraq as a League of Nations mandate, put down the 1920 revolt with aerial bombardment, and retained bases and oil rights long after nominal independence in 1932.
Iraq was assembled from three Ottoman provinces to suit British strategic and oil interests and given a king from another country.
