Treaty of Washington (1900)

The Treaty of Washington of 1900 was signed on November 7, 1900, and came into effect on March 23, 1901, when the ratifications were exchanged. The treaty sought to remove any ground of misunderstanding growing out of the interpretation of Article III of the 1898 Treaty of Paris by clarifying specifics of territories relinquished to the United States by Spain. It explicitly provided:

Spain relinquishes to the United States all title and claim of title; which she may have had at the time of the conclusion of the Treaty of Peace of Paris, to any and all islands belonging to the Philippine Archipelago, lying outside the lines described in Article III of that Treaty and particularly to the islands of Cagayan Sulu and Sibutu and their dependencies, and agrees that all such islands shall be comprehended in the cession of the Archipelago as fully as if they had been expressly included within those lines.[1]

In consideration for that explicit statement of relinquishment, the United States agreed to pay to Spain the sum of one hundred thousand dollars ($100,000) within six months after the exchange of ratification.[1][2] The Treaty of Washington is also known as the Cession Treaty.[3]
