Gold in the Philippines
October 2003
The Philippine archipelago, with over 7,000 islands that stretch for 1,100 miles north-south, was settled by Malaysians several thousand years ago. Ferdinand Magellan landed and was killed there in 1521. Spaniards took over the islands in 1571, and founded Manila, which is located on a large natural harbor. After the Spanish-American war in 1898, the United States took over the Philippines, and found itself in a brutal 6-year war before gaining control of all of the islands.
