In the elections for the first Knesset, Mapam received 19 seats, making it the second-largest party after the mainstream Labor Zionist Mapai. The party did not allow non-Jews to be members at the time, but it also set up an Arab list, the Popular Arab Bloc, to contest the elections (a tactic also used by Mapai, with whom the Democratic List of Nazareth was affiliated). However, the Arab list failed to cross the 1% electoral threshold. After the elections, the party conducted extensive negotiations with Ben-Gurion for inclusion in the coalition government, but was eventually excluded.[3] During the session it gained one seat when Eliezer Preminger joined after leaving Maki and then setting up his own party, the Hebrew Communists.
In the 1951 elections the party dropped to 15 seats and again was not included in the coalition. But it did become the first Zionist party to have an Israeli Arab, Rostam Bastuni, representing it in the Knesset.
This created a split in the party. Avraham Berman, Rostam Bastuni and Moshe Sneh left the party and set up the Left Faction, while Hannah Lamdan and David Livschitz created their own party, the Faction independent of Ahdut HaAvoda. Bastuni later returned to Mapam, but Berman and Sneh eventually joined Maki and Lamdan and Livschitz joined Mapai. Four other party members left to recreate Ahdut HaAvoda, though the Knesset speaker did not recognize the group as an independent party during the Knesset session. It also displeased the USSR.
Although it had been reduced to seven seats by the end of the second Knesset, the party picked up nine seats in the 1955 elections. Having effectively renounced the Soviet Union, Mapam was now included in Ben-Gurion's coalitions for both the seventh and eighth governments. But it was to blame for Ben-Gurion's resignation and the collapse of the government on 5 July 1959 when it and Ahdut HaAvoda voted against the government on the issue of selling arms to West Germany but refused to leave the coalition.
In the 1959 elections the party retained its nine seats, and despite their previous differences, were included in Ben-Gurion's coalition.
In the 1961 elections it again won nine seats, but this time was not part of the governing coalition.
The 1965 elections saw Mapam lose a seat, dropping to eight mandates, but enter the coalition government. In January 1969 the party formed an alliance with the Israeli Labor Party, which was named the Alignment. The Alignment went on to win the highest-ever number of seats in the 1969 elections (56 out of 120). At the time, Soviet commentators called Mapam "one of the most reactionary ones among the left-socialist parties".[4]
As a result of its declining support, Mapam joined with Ratz and Shinui to form Meretz, a new left-wing, social-democratic and pro-peace alliance, which became the third-largest party in the Knesset in the 1992 elections.
In 1995 the party's newspaper, Al HaMishmar, ceased publication.
In 1997 the merger into Meretz with Ratz and part of Shinui (much if not most of Shinui's membership did not agree with the merger, and reformed as an independent party headed by Avraham Poraz) was formalized, and Mapam (and Ratz) ceased to exist.
From 1951 to 1979, Mapam also published an Arabic newspaper, Al-Mirsad (Observation Post, a similar name to the Hebrew newspaper Al HaMishmar, which means "on the lookout"). It appeared weekly, except for a short period as a daily.[5]
1948 policy towards Arabs
Mapam entered the 1948 coalition government with a radically different policy towards Arab civilians from that pursued by David Ben-Gurion. Mapam's executive committee advocated Jewish–Arab coexistence, opposed the expulsion of civilians and was in favor of the right of refugees to return to their homes after the war.[6] In June 1948 all cadres were issued with a policy statement, "Our policy towards Arabs during the war", written by Aharon Cohen, the Head of Mapam's Arab Affairs Department.[7] Mapam particularly opposed the destruction of Arab houses. Aharon Zisling, one of two Mapam members of the cabinet, raised the issue repeatedly toward the end of June.[8] At a Mapai Centre meeting, 24 July 1948, Ben-Gurion accused Mapam of hypocrisy; citing events at Mishmar HaEmek, he said: "They faced a cruel reality ... [and] saw that there was [only] one way and that was to expel the Arab villagers and burn the villages. And they did this, and they were the first to do this."[9]
Mapam also opposed the establishment of settlements on Arab land. But this created a dilemma as the kibbutz movement ideologically closest to Mapam, Kibbutz Artzi, was in the vanguard of the settlement movement. Of 12 new settlements created during May and June 1948, six were Mapam-related groups.[10] In August 1948, proposals were put forward for the creation of 32 new settlements, all but five of which were beyond the proposed UN partition frontier. As a compromise Mapam agreed on condition that there was sufficient "surplus land" at each location to allow for the original inhabitants' return.[11] In the following months Mapam further diluted its position on the right of refugees to return by adding that there should be no return while a state of war existed and then it should only apply to the "peace-minded".[12] With the explosion of opposition to the Government's proposal to the UN, 28 July 1949, that 100,000 might be allowed to return, the issue of return quietly dropped off the agenda.[13]
MAPAM conference at Kibbutz Givat Brenner. November 1948
The gulf between policy makers in the executive and Mapam members who dominated the leadership of the armed forces was again revealed following the military operations in the autumn of 1948. In early November the editor of the Mapam newspaper, Eliezer Pra'i, received a letter describing events at al-Dawayima. There followed a meeting of the Political Committee, 11 November 1948, which was briefed by recently ousted Chief of Staff of the Haganah, Yisrael Galili, about the killing of civilians during Operations Yoav and Hiram. Cohen led a call for an independent inquiry.[14] The problem for Mapam was that the commanders of these operations were senior Mapam members Yitzhak Sadeh and Moshe Carmel. It was agreed to accept Ben-Gurion's internal inquiry.
In December, party co-leader Meir Ya'ari publicly criticised the IDF for using the expulsion of civilians as an "imperative of strategy". This was probably directed at Mapam member Yigal Allon, who had been chief of operations during Operation Danny.[15]
