Boundary Treaty of 1866

Bolivia and Chile negotiated the "Boundary Treaty of 1866," or the "Treaty of Mutual Benefits," which established 24° S "from the littoral of the Pacific to the eastern limits of Chile" as the mutual boundary. Both countries also agreed to share the tax revenue from mineral exports from the territory between 23° and 25° S. The bipartite tax collecting caused discontent, and the treaty lasted for only eight years.
