How did the Yahudus HaTorah party get the “gimmel” line? I doubt they were the third party to exist in the State. They are probably the legal successors of the original Agudas Yisroel party that existed prior to the Degel split off. Did the original Agudas Yisroel have gimmel?
Agudath Israel was one of the original parties in 1949, and they got the “gimel” which has passed on to Yahudus HaTorah. Back then the religious parties were much more unified (okay, the fact that the Communists were the second largest party and threatened to win was a factor in encouraging religious unity – when it finally became apparent that Israel wasn’t going to ally with Stalin, that unity started to break down).
Correction: In 1949 they were “Beis” (united with the Religious Zionists). When they split for the following election, the Religious Zionists kept “Beis” and Agudah got “Gimmel.”
