The first Reform congregation in Israel opened in Jerusalem in 1958, and it was named Congregation "Har'el". A conference open to the public who wished to see a Jewish alternative to the Orthodox Movement took place in 1965. This strengthened the relationship between the six existing congregations, and served as the cornerstone for the establishment of the Israel Movement for Progressive Judaism (IMPJ). The IMPJ officially became an organization in Israel in 1971. The Hebrew Union College-Jewish Institute of Religion, the rabbinical college of Reform Judaism, began its Rabbinical Studies program in Israel in 1974, and in 1980, the first Reform rabbi was ordained by the HUC. The headquarters of the World Union for Progressive Judaism was moved to Jerusalem in 1973.
