In addition to Spanish Colonization, the Philippines have also suffered in more recent history from American colonization that still persists to this day. On December 10, 1898, Spain surrendered the Philippines to the United States through the Treaty of Paris. This began a long period of American colonization, which played a huge role in Philippine archaeology as it enabled American anthropologists to explore vast archaeological sites with profound evidence of human occupation and evolution. Later, archaeologists like H. Otley Beyer were able to put the Philippines in the archaeological record through events such as the 1904 St. Louis World's Fair, which initiated the development of archaeology in the Philippines.
