'Rebellion', an abbreviation for מר"ימחנה רדיקלי ישראלי Mahaneh Radikali Yisraeli or Israeli Radical Camp) was a minor radical left-wing political party in Israel.
It surprisingly passed the electoral threshold in the 1965 election, gaining 1.2% of the vote and one seat, taken by Avnery.
However, disagreements between Avnery and Cohen led to the party breaking up on 4 January 1972.
Cohen served the remainder of the Knesset session as an independent MK, whilst on 3 July 1973 Avnery renamed the party Meri.
Prior to the 1977 elections, the party merged with Moked, the Independent Socialist Faction and some members of the Black Panthers to form the Left Camp of Israel.
