Proclaiming a republic after occupation
Japanese occupation reorganized colonial institutions and expanded political organizations and youth military training. Requisitioning, forced labor and shortages disrupted communities. After Japan accepted surrender terms in August 1945, activists pressed Sukarno and Hatta to proclaim independence. Sukarno read the declaration in Jakarta on August 17 with Hatta present. Radio, newspapers and copied texts carried the announcement. Flag raising, meetings and takeovers expressed support, while the timing and organization of action varied between islands and local communities.

Revolutionary war and sovereignty transfer
Allied arrivals and Dutch efforts to restore colonial rule brought resistance in towns and countryside. Fighting at Surabaya and Dutch offensives in 1947 and 1948 accompanied diplomacy and guerrilla activity. Truces altered areas of control, with UN mediation and international pressure influencing negotiations. The Hague Round Table Conference produced arrangements for sovereignty transfer in 1949. A federal republic received sovereignty at year’s end and became a unitary republic in 1950. Reconstruction followed amid continuing relationships between armed forces, parties and local organizations.
