All other Spanish islands in the West Indies, together with Guam in the Ladrones, were ceded to the United States.

The whole archipelago of the Philippines, with water boundaries carefully but not quite accurately drawn, was ceded to the United States, which by the same article agreed to pay Spain $20,000,000.

All claims for indemnity or damages between the two nations, or either nation and the citizens of the other, were mutually relinquished, the United States assuming the adjudication and settlement of all claims of her own citizens against Spain.
This treaty, even more than the act of war, marked a turning point in the relation of the United States to the outside world.

So violent was the opposition of those who disapproved, and so great the reluctance of even the majority of those who approved, to acknowledge that the United States had emerged from the isolated path which it had been treading since 1823, that every effort was made to minimize the significance of the beginning of a new era in American history.

It was argued by those delving into the past that the Philippines actually belonged to the Western Hemisphere because the famous demarcation line drawn by Pope Alexander VI, in 1493, ran to the west of them; it was, indeed, partly in consequence of that line that Spain had possessed the islands.
