The Jewish immigration to Puerto Rico began in the 15th century with the arrival of Crypto-Jews, or Secret Jews who accompanied Christopher Columbus on his second voyage. An open Jewish community did not flourish in Puerto Rico because Judaism was prohibited by the Spanish Inquisition, however many migrated to mountainous parts of the island, far from the central power of San Juan, and continued to self-identify as Jews and practice Crypto-Judaism.
Puerto Rican Jews have made many contributions in multiple fields, including business and commerce, education, and entertainment. Puerto Rico has the largest and richest Jewish community in the Caribbean, with over 3,000 Jewish inhabitants. It is also the only Caribbean island in which all three major Jewish denominations—Orthodox, Conservative, and Reform—are represented.
The Shaare Zedek Temple, in San Juan, Puerto Rico was founded in 1953, became the first Conservative synagogue. Its name means "Gates of Justice," and was taken from a synagogue that was destroyed in Leipzig, Germany. It is headed by Rabbi Gabriel Isaías Frydman, originally from Argentina.
