Query: In what year did Somalia become independent?
Context: A referendum was held in neighboring Djibouti (then known as French Somaliland) in 1958, on the eve of Somalia's independence in 1960, to decide whether or not to join the Somali Republic or to remain with France. The referendum turned out in favour of a continued association with France, largely due to a combined yes vote by the sizable Afar ethnic group and resident Europeans.
