of the 19th century, immigrants mainly from Germany, England and Ireland settled in the city. Many of these immigrants were Catholic which fueled anti-Catholic feelings and organizations. In the 1840s Philadelphia became a major base for anti-Catholic Protestant groups which soon led to deadly riots in 1844. However, by the end of the 19th century, Roman Catholics had become the largest single denomination in Philadelphia, though all Protestant denominations combined remained a majority of the Christians in Philadelphia into the present day. During the last decades of the 19th century and the first half of the 20th century, the origin of immigrants shifted from England, Ireland, and Germany to Italy, Southern Europe, Russia, Poland, and Eastern Europe. Italians and Poles helped increase the city's Catholic population, but Jewish immigrants, mainly from Poland, Lithuania, and Russia, were the largest religion to settle in the city during this period. Supplementing the already settled German Jews, the city's Jewish population swelled from 5,000 in 1881 to 100,000 in 1905. Philadelphia's Italian population changed from 300 in 1870 to 77,000 in 1910. Hungarian and Polish immigrants also settled in the city, but in smaller numbers. In the 20th century political power began to shift from primarily white Protestants to Irish and Italian Catholics and Jews, with the city's first Catholic and Jewish mayors elected in 1963 and 1992 respectively. 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
