Prior to its creation as an independent province, Agusan was divided between the provinces/districts of Misamis, and Surigao during the Spanish colonial period. In 1907, Agusan was separated from Misamis, and Surigao creating the Agusan province through the sub-provinces of Bukidnon, and Butuan.
The sub-province of Bukidnon became an independent province in 1914 through Act No. 2408 and Butuan sub-province assumed the name of Agusan. Both Agusan and Bukidnon were put under the Department of Mindanao and Sulu from 1914-1920.
