在朝鮮アメリカ陸軍司令部軍政庁
Residents of Jeju island were some of the most active participants in the Korean independence movement against colonial Japanese occupation. Due to the island's relative isolation from the mainland peninsula, Jeju experienced relative peace after the Japanese surrender, contrasting with the period of heavy unrest in the southern region of mainland Korea. As with the mainland, the period immediately following the Japanese surrender was characterized by the formation of People's Committees, local autonomous councils tasked with coordinating the transition towards Korean independence. When the American military government arrived on Jeju in late 1945, the Jeju People's Council was the only existing government on the island. As a testament to this relative stability, the US military governor under the United States Army Military Government in Korea (USAMGIK) John R. Hodge stated in October 1947 that Jeju was "a truly communal area that is peacefully controlled by the People's Committee without much Comintern influence."
