As in most of the country, Roman Catholicism plays a prominent role in the celebration of holidays, including ''Las Fiestas Agostinas'' (The August Festivals) in honor of Jesus Christ, the Patron saint of El Salvador, referred to as ''El Salvador del Mundo'' (The Savior of the World). These events are becoming less prominent with a sharp decline in the Roman Catholic population during the past decade. San Salvador is also home to about 3,500 Jews; the Jewish community is still robust, but less so since the 1980s, as a large number of them left with the start of the Salvadoran Civil War. Many Jews had migrated to El Salvador during World War II due to the work of José Castellanos Contreras, the Salvadoran diplomatic Consul General in Geneva, Switzerland, who helped a Jewish-Hungarian businessman named Gyorgy Mandl save up to 40,000 Jews in Central Europe from the Nazi persecution by giving them Salvadoran nationality papers. The city has a small community of Palestinians, mostly descendants of Palestinian Christian families who immigrated from Palestine in the late 19th and early 20th century, with the highest rate of immigration between 1910 and 1925. The city also has Korean Evangelical Churches that hold services in Korean for a growing Korean population.
