World War II, which played a major role in Solomons history, did not have a major impact upon Malaita. Auki became the temporary capital when Tulagi was seized by the Japanese, and it too was briefly raided by Japan, but little fighting happened on the island. Malaitans who fought in battalions, however, brought a new movement for self-determination known as Maasina Ruru (or "Marching Rule"), which spread quickly across the island. Participants united across traditional religious, ethnic, and clan lines, lived in fortified nontraditional villages, and refused to cooperate with the British. The organization of the movement on Malaita was considerable. The islands was divided into nine districts, roughly along the lines of the government administrative districts, and leaders were selected for each district. Courts were set up, each led by a custom chief ("alaha'ohu"), who became powerful figures. The British initially treated the movement cautiously, even praised aspects of it, but when they found there could be no common ground between the government and the movement, retaliated firmly, with armed police patrols, insisting that the chiefs recant or be arrested. Some did recant, but in September 1947 most were tried in Honiara, charged with terrorism or robbery, and convicted to years of hard labour.
