In the late 19th century, the Recollects (under protest) turned over many of their mission territories, including those in the upper Agusan region, to the reconstituted Jesuit order (the Jesuits had been banned by Papal edict in the 1760s, and ejected from the Philippines in 1768). Missionary work was interrupted by the Philippine Revolution when the Jesuits either fled or were arrested by revolutionaries. During the American occupation, lumbering became an important activity in Agusan del Sur. Visayan migrants settled in the cleared plains, pushing indigenous communities farther into the mountainous slopes.
