The Spanish city of Manila was founded on June 24, 1571, by Spanish ''conquistador'' Miguel López de Legazpi. This is regarded as the city's official founding date; however, a  Tagalog-fortified polity called Maynilà had already existed on the site, dating back as far as 1258. It is the name of this old polity from which the Spanish and English name Manila derives. After the defeat of the polity's last indigenous Rajah, Sulayman III, in the Battle of Bangkusay, a fortified Spanish city called Intramuros was built directly on top of the site of old Maynilà. Manila was the seat of power for most of the country's colonial rulers. Today, it is home to many historic sites, some of which were built during the 16th century. Many of the Philippines' "firsts" are in Manila, including the first university (1590), light station (1642), lighthouse tower (1846), water system (1878), hotel (1889), electricity (1895), oceanarium (1913), stock exchange (1927), flyover (1930s), zoo (1959), pedestrian underpass (1960), science high school (1963), city-run university (1965), city-run hospital (1969), and rapid transit system (1984) – also considered to be the first rapid transit system in all of Southeast Asia).
