The airport area to the east of Honiara was the site of a battle between the United States and the Japanese during the Guadalcanal Campaign in World War II, the Battle of Henderson Field of 1942, from which America emerged victorious. After Honiara became the new administrative centre of the British Solomon Islands Protectorate in 1952 with the addition of many administrative buildings, the town began to develop and grow in population. Since the late 1990s, Honiara has suffered a turbulent history of ethnic violence and political unrest and is scarred by rioting. A coup attempt in June 2000 resulted in violent rebellions and fighting between the ethnic Malaitans of the Malaita Eagle Force (MEF) and the Guadalcanal natives of the Isatabu Freedom Movement (IFM).
