In the second half of the 19th century immigration began from Latin America, mainly from Puerto Rico and Cuba. By the end of the 20th century Puerto Ricans became the largest Latino group in Philadelphia. Starting in the 1950s large numbers of Puerto Ricans settling primarily in North Philadelphia. Immigrants from China founded Chinatown in the 1870s and 1880s; over the next century, the neighborhood grew into a diverse community with immigrants from many Asian countries. By the 21st century, Philadelphia's two largest Asian ethnic groups were the Chinese and Koreans. Philadelphia became the earliest recorded East Coast city with a Korean community in the 1880s; early members were largely political exiles supporting Philip Jaisohn. Immigration from the Middle East to Philadelphia began as early as the 1880s with immigrants primarily from Lebanon. Starting in the 1960s immigrants from other Middle Eastern countries, such as Syria, the Palestinian territories and Iraq moved to the city. Other immigrants from Asia during the last decades of the 20th century include Indians, Vietnamese and Cambodians. Another community who established an identity in Philadelphia during the 20th century was the gay community. The city's homosexual community is centered in a portion of Washington Square West, nicknamed the "gayborhood" by residents.
