Be'er Ya'akov was established in 1907 on 2,000 dunams of land purchased by a company headed by Meir Dizengoff from a Lutheran German colony the previous year. It was divided into two sectors, one for immigrants from Russia, Poland, Romania, Bulgaria, Argentina, and Iran, and the other for Mountain Jews from Dagestan. It was named after Ya'akov Yitzhaki, a rabbi and pioneer from the Mountain Jewish community.[3] Yitzhaki headed the Mountain Jewish pioneers who settled there.
