Republic of Agusan (Maharlika Timeline)

The Republic of Agusan-Surigao (Butuanese: Republika hong Agusan-Surigao, Surigaonese: Republika nan Agusan-Surigao, Spanish: Republica de Agusan-Surigao) was a country in northeastern Mindanao that existed in the aftermath of World War II, and was found by nationalists in northeastern Mindanao.

After the Second World War, Butuanese and Surigaonese-speaking nationalists made it plain that being under foreign rule has only made their people suffer to endless bounds. Nationalists wanted a nation ruled by the glory of the historical Rajahnate of Butuan, and similar to Emilio Aguinaldo's Tagalog-based Katipunan, Federico Siagu, a self-proclaimed descendant of Rajah Siagu, the last rajah of Butuan, organized the Fuerza de Butuan, a militant-society that battled the Japanese forces and took on ancient influences.

In 1945, after the Americans gave the Philippines its independence, Federico Siago rejected Philippine rule over Butuan, and the Fuerza de Butuan went to war against the Philippine Armed Forces and proclaimed himself the First President of Butuan.

The republic gained sympathy from the Moro sultans, who also shared a hatred of the Philippines, who referred to Federico as the "Rajah of Butuan". In 1950, the Visayan National Army invaded Butuan. Federico Siagu would led the Butuanese and Surigaonese against the Visayan Nationalists.

However in 1951, Federico Siagu saw that the broader Maharlikan Revolution was attempting to unite all of the indigenous peoples, embracing indigenous customs over Spanish ones. President Siagu accepted Maharlikan rule. First Maharlikan president Atiqullah Gumabay greeted Federico Siagu warmly and allowed him to become the Yang Megat (Provincial Governor) of Butuan.
