Soon after Xiamen became a treaty port resulting from China's loss in the First Opium War and the Treaty of Nanking in 1842, foreign residents on the island established an informal organization that became formally organized several decades later when its Land Regulations were approved by the government of China in May 1902.[3] Eventually 13 countries, including Great Britain, France, The Netherlands and Japan, were to enjoy extraterritorial privileges there and take part in the Kulangsu Municipal Council that administered the settlement. As with the Shanghai International Settlement, the British played a predominant role in the administration and Sikh policemen from British India were charged with the policing of the Settlement. The consulates, churches, hospitals, schools, police stations, etc. built by those foreign communities explain the predominantly Victorian-era style architecture that can still be seen throughout Gulangyu. Japanese occupation of the island began in 1942, and lasted until the end of World War II. The Hokkien dialect is spoken on the island, as it is in Xiamen.
