Matzpen (, lit. 'Compass'), founded in 1962, was an Israeli revolutionary socialist and anti-Zionist organisation. It was active until the 1980s. Its official name was the Socialist Organisation in Israel, but it became better known as Matzpen after its monthly publication.

Origins The organisation was founded by former members of the Israeli Communist Party – Maki – who opposed that party's unquestioned support for the international policies of the Soviet Union. They offered a more radical analysis of and opposition to Zionism.Lutz Fiedler, Matzpen. A Different Israeli History, in: Chen Jian, Martin Klimke, Masha Kirasirova, Mary Nolan, Marilyn Young, Joanna Waley-Cohen (eds.), The Routledge Handbook of the Global Sixties: Between Protest and Nation-Building, London: Routledge, 2018, pp. 457–468. An early analysis of the Arab–Israeli conflict, written before they left the Communist Party, by Moshe Machover and Akiva Orr (using a pseudonym, N. Israeli), appeared in Hebrew in 1961 under the title of Shalom, Shalom ve'ein Shalom (שלום, שלום, ואין שלום; Peace, Peace When There is No Peace – an English translation was completed in 2009; although still unpublished as of August 2016, the translation is available online). Matzpen drew together Jewish and Arab activists with various backgrounds in left-wing organisations and affiliations. Prominent among them was Jabra Nicola, a Palestinian-Israeli intellectual and activist who helped shape the theoretical orientation of the nascent organisation. It published a magazine of the same name in Hebrew and Arabic. The organisation grew in the period after the 1967 Six-Day War and Israel's occupation of Palestinian and Arab territories.Ran Greenstein, "Class, Nation, and Political Organization: The Anti-Zionist Left in Israel/Palestine", International Labor and Working Class History, 75 (Spring 2009): 85–108

Core positions In a statement titled "Down with the Occupation", from 1 January 1969, Matzpen distinguished itself – together with the Communist Party (Rakah) – as the only forces conducting "a consistent struggle against the continued occupation of the territories conquered in June '67". Faced with a situation in which "Israel controls the whole of the Palestine Mandate territory as well as vast tracts of Egyptian territory and a region in the south of Syria", Matzpen asserted in "General Declaration by the ISO" in March 1968, that "It is both the right and duty of every conquered and subjugated people to resist and to struggle for its freedom. The ways, means and methods necessary and appropriate for such struggle must be determined by the people itself and it would be hypocritical for strangers - especially if they belong to the oppressing nation – to preach to it, saying, 'Thus shalt thou do, and thus shalt thou not do.'" It added, that despite its recognition of "the unconditional right of the conquered to resist occupation", as an organization it could support politically "only such organizations which, in addition to resisting occupation, also recognize the right of the Israeli people for self-determination" in order to enable "a joint struggle of Arabs and Jews in the region for a common future."

In this context, Matzpen's aim was to create a broad front of people opposed to the occupation and in favour of a de-Zionized Israel, which would form part of a socialist federation of the entire Middle East. In contrast to the Communist Party and the Zionist Left, Matzpen insisted that the 1967 occupation was but one stage in the long history of Zionist settlement, and reversing it would be a necessary but not sufficient condition for overall solution to the problems of the Middle East. For such a solution, political mobilization of Arabs, Jews, and other national minorities in the region would be needed. The political framework for this mobilization became known as the Arab Revolution, which combined national and socialist tasks in the process of struggle against Zionism, imperialism and Arab reaction.Jabra Nicola and Moshe Machover, "The Palestinian Struggle and Revolution in the Middle East", Matzpen 50, August 1969, To advance these aims, Matzpen established links with New Left organisations in Europe and other parts of the world, and also with progressive Palestinian organisations, such as the Democratic Front for the Liberation of Palestine.

Many of the original analyses and statements of the organisation were included in a published collection under the title The Other Israel: The Radical Case Against Zionism, edited by Arie Bober (Doubleday, 1972). Bober's book provided an overview of the positions held by Matzpen at the time on a range of issues, and thus is an essential resource on the organisation's analysis of Israeli society and the Israeli-Palestinian conflict. In the introduction to the book he offers this summation of the group's outlook: "This book is the result of five years' collective effort by a small group of Arab and Jewish citizens of Israel to penetrate the dense net of illusion and myth that today dominates the thinking and feeling of most Israelis and, at the same time, largely determines the prevailing image of Israel in the Western world. According to the Zionist fairy tale, the state of Israel is an outpost of democracy, social justice and enlightenment, and a homeland and haven for the persecuted Jews of the world. This outpost, so the story goes, though earnestly seeking peace with its neighbors finds itself in a state of perpetual siege because of the greed of Arab rulers, the inherent "unreasonableness" of the Oriental mind and the innate Gentile proclivity toward hatred of the Jews.

"The reality, this book demonstrates, is utterly different. The Zionist state was born in the violent expropriation and expulsion from their country of the Palestinian Arabs, and that process continues today. In open alliance with Western, especially United States, imperialism, and in scarcely hidden collusion with the most reactionary forces in the Arab world, the Zionist state actively sets itself against every step, no matter how faltering, taken by the Arab masses to alleviate the centuries' old misery imposed on them by colonialism and imperialism. Within the territories occupied since 1967, the Zionist state employs a system of direct military repression to expel Palestinian Arabs from their lands and secure Jewish colonization of them, and to crush every expression of Palestinian resistance. Within its own borders, the Zionist state engages in systematic national oppression of its minority of Arab citizens. The dark-skinned majority of the privileged Jewish community itself increasingly feels the sting of racist discrimination, as economic inequality increases and social conditions deteriorate. Far from offering a haven to the persecuted Jews of the world, the Zionist state is leading new immigrants and old settlers alike toward a new holocaust by mobilizing them in a colonial enterprise and a counterrevolutionary army against the struggle of the Arab masses for national liberation and social emancipation – a struggle that is not only just but will eventually be victorious. This state of affairs is, moreover, in no sense accidental. It was the inevitable outcome of the success of the Zionist project to establish a Jewish state in Palestine. And to change this reality requires not merely a change of government or a modification of one or another specific policy, but a revolutionary transformation of the very foundations of Israeli society."

Matzpen outside Israel

In the late 1960s and early 1970s, supporters of Matzpen abroad published Israca (Israeli Revolutionary Action Committee Abroad). The magazine included many articles published in Matzpen. Some of Matzpen was censored and that material was republished in Israca. Moshé Machover, Eli Lobel, Haim Hanegbi, and Akiva Orr were all part of the editorial board. In the late 1970s and early 1980s, supporters of the organisation and other radical left academics and activists formed another journal in the UK, Khamsin, in which they published their analyses of current events. A selection of material from Khamsin was published under the title Forbidden Agenda: Intolerance and Defiance in the Middle East (Saqi Books, 2000).

Splits and debates In 1970 the organisation started going through a process of ideological and organisational fragmentation, with some members leaving to form new groups, such as Avangard with a Trotskyist orientation, led by Menahem Carmi and Sylvain Cypel, and Ma'avak (Revolutionary Communist Alliance), with a Maoist orientation, led by Ilan Albert and Rami Livneh. A further split within the latter organisation saw the formation of the led by Udi Adiv and Dan Vered. Avangard also underwent splits, which saw the formation of the Spartacist League in 1974 and the Nitzotz group in 1977.Details in Ran Greenstein, "Socialist Anti-Zionism: A chapter in the history of the Israeli radical left", Socialist History, 35 (2009): 20-39

The theoretical debates that led to the splits in Matzpen had to do with the conceptualization of the relations between class struggle and nationalism in the struggle for socialism. Avangard regarded Israel as a normal capitalist society in which the working class was the primary revolutionary agent. Hence, it saw its goal as the mobilization of that class to create an Israeli socialist republic. It regarded Matzpen's focus on the Israeli-Palestinian national conflict and on the colonial origins of Israeli society as a distraction from the class struggle. Ma'avak, in contrast, saw Matzpen as not emphasizing enough the colonial character of Israeli society. It saw its goal as that of facilitating the Palestinian national liberation struggle as a necessary step towards socialism. In response to both groups, Matzpen re-asserted its combination of support for national and social struggles.

A major split within the core group of mainstream Matzpen took place in 1972, and both factions kept the name Matzpen for their respective journals, an issue that gave rise to sharp dispute between them. The obvious value of the 'Matzpen' label as a marker of radical left-wing politics was behind that decision. Most of the original leadership remained in what became known as Matzpen Tel Aviv, while the other faction became known as Matzpen Jerusalem. That latter group adopted the name Matzpen Marxist, to distinguish itself from its rivals. In 1975 it changed its name to Revolutionary Communist League, section of the Fourth International, while retaining the title Matzpen Marxist for its regular publication. The Tel Aviv group also changed its name subsequently (in 1978) to the Socialist Organization in Israel and dropped the adjective 'Israeli' in order to avoid possible association with Zionism. Both groups retained the original Matzpen dual focus on class and national liberation. Machover, Orr and Haim Hanegbi remained with the Tel Aviv based group, while the Jerusalem-based group was led by Arieh Bober and Michel Warschawski (Mikado). A youth movement known as Hafarperet (mole) was affiliated with the latter group, and was active in the mid-1970s, mostly in Haifa.
