Overview
This lecture discusses the Battle of Medan Area (1945-1947), highlighting Indonesia's fight to defend its independence against Allied and Dutch forces after its 1945 proclamation.
Background to the Battle
- After Japan’s surrender in WWII (August 1945), Indonesia declared independence on August 17, 1945.
- Many countries, especially the Netherlands, refused to recognize Indonesia’s independence, seeing it as their colony.
- Allied forces (including Britain and the Netherlands) planned to “maintain order” in former Japanese colonies, including Indonesia.
- The Allied Forces Netherlands East Indies (Afnei) aimed to accept the Japanese surrender and return civil authority to Dutch control (via NICA).
Escalation in Medan
- News of independence reached Medan on August 27, 1945, sparking mass celebration.
- Allied troops, including Dutch NICA members, arrived in North Sumatra in October 1945.
