Prewar
During the German colonial era, a Lutheran mission, and Siar plantation were established. In the early 1900s, Lutheran missionary Wilhelm Blum lived on Siar Island and worked on Ragetta Island (Kranket Island) until the early 1920s. Afterwards, the Catholic Church established the Sacred Heart Catholic Mission on Siar Island.

Wartime History
On December 18, 1942 the Japanese Army occupied the Madang area. During the Japanese occupation of the Madang area, Lutheran Missionaries from Madang and Alexishafen were interned on Siar Island. The internees included Reverend Theodore G. Braun from the Lutheran Mission in Madang. By late April 1944, the Japanese abandoned Siar Island.
