North Yemen became independent of the Ottoman Empire in 1918. The British who had set up a protectorate area around the southern port of Aden in the 19th century withdrew in 1967 from what became South Yemen. Three years later the southern government adopted a Marxist orientation. The massive exodus of hundreds of thousands of Yemenis from the south to the north contributed to two decades of hostility between the states.
