Colombian-Peruvian Border Dispute 1911

Four subsequent treaties between Colombia and Peru--signed in 1906, 1909, 1911, and 1922--also dealt with boundary claims and charges of Peruvian penetration into southern Colombia's Putumayo region. The 1906 treaty affirmed both countries' willingness to withdraw from the area while ownership of the disputed territory was settled by arbitration. Colombia revoked the treaty during the following year, however, and troops from both countries moved back into the region. The 1909 treaty attempted to end the continuing fighting among the settlers in the region as well as between the settlers and the region's Indian population. Although both countries agreed to work toward an arbitrated settlement, the issue was never submitted for arbitration.

In 1911 Peruvian troops attacked the Colombian garrison at the river town of Puerto Córdoba, giving rise to the July treaty in which both countries agreed to limit the number of troops in the area. The 1922 treaty recognized the legitimacy of Colombia's boundary on the Amazon River and provided for free navigation of the river by both countries. Because of continuing objections to the treaty's terms, however, Peru did not ratify the treaty until 1928. Upon Peru's ratification of the pact, it was widely believed that the Putumayo dispute had at last been resolved. Two years later, Colombia took possession of its territory in the region.
