In the 1860's, the beginnings of Boise's Jewish Community existed in the early mining camps. As Boise became settled, Jewish people met in private homes to celebrate the Holidays. In 1895, a group of 25 Jewish residents of Boise joined together to form Congregation Beth Israel.

The building which houses Congregation Ahavath Beth Israel today has a long history and illustrious history in Boise and the State of Idaho. It is considered the oldest synagogue west of the Mississippi River in continuous use since 1896, the year that it was built. The building, which is a Moorish design was restored and rededicated in 1982.

About the time of World War I, several Jewish families joined together to form Congregation Ahavath Israel. In 1947, their synagogue was built at the corner of 27th and Bannock Streets.

In the the summer of 1986, both congregations come together as one, forming Ahavath Beth Israel. The congregation is composed of approximately 210 families, has a full time Rabbi and is the center for Judaism in Idaho.
