Nathan Yellin-Mor

Nathan Friedman-Yellin was born in Grodno on June 28, 1913; the city is now Hrodna, Belarus.[1][2] He completed engineering studies in Warsaw, where he joined the Revisionist Zionist movement and Betar.[2] Before moving to Palestine, he was a Betar officer and an Irgun activist in Poland, combining organizational work with the journalism that would remain an important part of his public life.[4]

In the summer of 1937, he met Avraham Stern in Poland while Stern was recruiting for the underground.[3] Yellin-Mor had become frustrated by what he regarded as the gap between Revisionist declarations and practical action, and he embraced Stern’s proposal for a struggle for independence against British rule and the establishment of a Jewish state.[3] Acting as Stern’s emissary, he traveled across Poland recruiting Betar members for the Irgun.[3] His association with Stern thus began before either his arrival in Palestine or his membership in Lehi.[3]

In 1938, Yellin-Mor and his friend Shmuel Merlin became editors of Die Tat, also rendered Di Tat, a Warsaw Yiddish newspaper associated with the Irgun.[2][3] The short-lived daily, which he edited in 1938–39, explained the Irgun’s positions on events in Palestine to Polish Jewish readers and urged them to leave Poland.[2][3] Its combination of political argument, underground advocacy, and concern for the future of European Jews characterized his work immediately before the Second World War.[3]

After the outbreak of war, Yellin-Mor and Frieda, also identified as Frida Morain, fled east and reached Vilna; they married during this period.[3][4] They eventually reached Tel Aviv in January 1941 and joined Stern’s Lehi organization, which had broken away from the Irgun.[2][3] Yellin-Mor adopted the underground name “Gera,” also rendered “Gara,” and became a close aide to Stern.[3][4] He and Frieda later had two children, Dorit and Elisha.[4]

In 1941, Stern sent Yellin-Mor to Syria on a mission intended to open a route through neutral Turkey and establish contact with representatives of Nazi Germany.[2] The proposed cooperation was directed against Britain, in exchange for the mass evacuation of European Jews to Palestine.[2] His assignment also involved seeking access to the Balkans and renewing contacts with potential supporters at a time when Lehi faced arrests, shortages of money and members, and declining public support.[5]

Traveling under the guise of an engineer, Yellin-Mor reached Aleppo.[3] British authorities traced him after searching his Tel Aviv home and finding his address in Syria, then arrested him and imprisoned him in Palestine.[2][3] He was held first at the Mazra'a detention camp and subsequently at Latrun.[4] Frieda was also arrested and confined in the women’s prison camp in Bethlehem, where she remained until her release at the end of 1947.[3]

Yellin-Mor learned in detention that Stern had been killed by the British in 1942.[2][3] Lehi had been weakened by arrests and departures, but he continued working to revive its underground activity.[3] Leaders maintained contact during imprisonment through coded notes and letters, preserving communication despite their confinement.[3] Yellin-Mor published “Breaking the Prisons,” calling on Lehi members to resume the struggle.[3]

On November 1, 1943, Yellin-Mor led an escape by a group of twenty Lehi detainees from Latrun.[3] They used a 75-meter tunnel dug beneath one of the camp’s shacks and concealed the excavated earth in a garden at its entrance.[3] The escape returned him and his colleagues to underground activity and was followed by his participation in Lehi’s central leadership.[2][4] The tunnel episode became one of the distinctive events of his underground career, linking his imprisonment with the organization’s subsequent revival.[2][3]

After Stern’s death, Lehi came under a three-person leadership consisting of Yellin-Mor, Yitzhak Shamir, and Israel Eldad.[2][3] Their responsibilities were divided: Shamir directed operations, Eldad handled propaganda, and Yellin-Mor took charge of political strategy and external relations.[3] Under this leadership, the organization continued military operations until 1948.[2] Yellin-Mor’s work therefore encompassed both the political direction of the underground and decisions about its use of force.[3]

He participated in major organizational decisions involving violence against individuals, including the attempted assassination of British High Commissioner Sir Harold McMichael and the killing of Lord Moyne in Cairo on November 6, 1944.[3] Lehi members Eliyahu Hakim and Eliyahu Bet-Zuri carried out the Moyne assassination.[3] In his later account of a meeting with Haganah commander Eliyahu Golomb, Yellin-Mor recalled warning that attacks on Lehi members would be answered.[3] Relations with other Jewish organizations were thus an important part of his responsibilities alongside confrontation with the British authorities.[3]

After Shamir was arrested in 1946 and exiled to Africa, he entrusted Lehi’s operations to Yellin-Mor, who became its de facto commander.[3][4] By this stage, the organization included people from the right and left, religious and secular members, and veterans of Betar, the Irgun, and Hashomer Hatzair.[3] Yellin-Mor advocated an armed political organization that would seek to “naturalize the Middle East,” while developing contacts and cells abroad.[3] His political responsibilities therefore extended beyond local underground operations to the organization’s intended regional orientation and overseas connections.[3]

Journalism remained part of his underground work.[6] In 1943, after Eldad’s arrest, Yellin-Mor, identified by the name Friedman, replaced him as editor of Ha-Hazit.[6] The newspaper continued until 1945 and had a more intellectual character than earlier Lehi publications, with substantial literary and critical sections as well as ideological essays.[6] This editorial activity accompanied his political leadership rather than belonging only to the later, parliamentary phase of his career.[3][6]

Following Israel’s establishment in 1948, Lehi was to be dismantled and its members incorporated into the Israel Defense Forces.[3] On September 17, 1948, Lehi gunmen assassinated United Nations mediator Count Folke Bernadotte in Jerusalem.[7] A four-member team ambushed his motorcade, and Yehoshua Cohen shot him; approval for the operation has been attributed to the organization’s three leaders, Yellin-Mor, Shamir, and Eldad.[7] That account does not identify a more specific individual role for Yellin-Mor in carrying out the attack.[7]

Israeli police arrested Yellin-Mor and other Lehi members after the assassination, and he was tried in a military court alongside Matityahu Schmulevitz.[2][3] Accounts differ on the verdict: the Jewish Virtual Library says he was acquitted of complicity in Bernadotte’s assassination but convicted of membership in a terrorist organization, while Encyclopedia.com says he was convicted for the assassination.[2][8] Britannica reports an eight-year sentence for underground activities; both Britannica and the Jewish Virtual Library say he was subsequently released under a general amnesty.[1][2] His release allowed him to enter parliamentary life as the representative of a party organized by former Lehi members.[2][3]

In the 1949 election, Yellin-Mor headed the Fighters’ List, also known as the Fighters or Lohamim ticket, and became its only representative in the first Knesset.[2] The party’s election platform opposed territorial concessions and the internationalization of Jerusalem, and warned against British and American imperialism.[9] Its slogan was “Death to the foreign enemies of independence.”[9] These positions belonged to the early statehood phase of his political career, before his later advocacy of accommodation with Israel’s neighbors.[2][3]

During a lengthy Knesset debate about transferring government offices to Jerusalem, Yellin-Mor rejected the partition of the city that he saw as implicit in moving the offices to West Jerusalem.[10] He declared that such a partition would never happen, and his speech prompted discussion that brought the Altalena affair back into the debate.[10] As the Fighters’ List’s sole member, he spoke for a small parliamentary formation rooted in the former underground rather than one of the established parties.[2][10]

Within the Fighters’ List, a majority supported the socialist direction associated with Yellin-Mor and Shamir, while a right-wing minority led by Eldad withdrew.[3] The party quickly faded, and Yellin-Mor was not elected to the second Knesset.[2][3] He did not find a lasting place in the existing parties and turned to private business.[3] His subsequent public activity developed through journalism, small political movements, and campaigns rather than another parliamentary term.[2][3]

In 1956, Yellin-Mor and Uri Avnery established Semitic Action, or Ha-Pe'ulah ha-Shemit.[2] Their initiative opposed Israel’s alliance with Britain and France during the Sinai campaign and sought a different regional political framework.[3] Boaz Evron was also associated with the movement’s founding.[6] Yellin-Mor and his associates worked on The Hebrew Manifesto, which presented the possibility of a Palestinian state alongside Israel.[3]

Semitic Action supported a Jewish-Arab federation in the territory of Mandatory Palestine as part of a wider Middle Eastern federation.[2] Its regional proposals also included a federation linking Palestinians, Israel, and Jordan.[6] These projects placed Arab-Jewish reconciliation and regional association at the center of Yellin-Mor’s post-parliamentary political work.[2][3] They differed markedly from the opposition to territorial concessions expressed by the Fighters’ Party during the 1949 election.[9]

Yellin-Mor edited Semitic Action’s political-literary biweekly Etgar, meaning “Challenge,” which continued publication until 1967.[2][3] He recruited writers including Meir Wieseltier, Dalia Ravikovitch, Dan Almagor, and Ehud Ben Ezer.[3] The publication presented itself as nonconformist and served as an intellectual and ideological platform for the movement.[6] Its literary contributions stood alongside political argument, continuing the combination of editorial work and ideological engagement found in his earlier newspaper activity.[3][6]

His international interests included opposition to French colonial rule in Algeria.[3] In 1960, Yellin-Mor and associates established a Committee for a Free Algeria and made contact with underground fighters opposing France.[3] On several international issues, he adopted a pro-Soviet position.[1] His political activity nevertheless included specific regional proposals for Israel and its neighbors, rather than only positions on the wider international alignment.[2][3]

After Avnery entered the Knesset in 1965, Yellin-Mor withdrew from direct political activity, but he continued to write and later took part in peace campaigns.[2][3] Following the Six-Day War, he became a leader of the Israeli peace camp, advocating the return of territories captured in the war and the establishment of a Palestinian state alongside Israel.[3] He signed petitions opposing Israeli army actions in the territories.[3] In September 1971, he traveled to the Soviet Union as a member of a six-person delegation sponsored by the Israeli Communist Party, Rakah.[3]

On September 5, 1971, Yellin-Mor also wrote to Egyptian president Anwar Sadat concerning Eliyahu Bet-Zuri and Eliyahu Hakim.[11] The letter formed part of appeals pursued through political and media channels after Sadat’s accession to power in September 1970.[11] His involvement in this matter maintained a connection with the memory of Lehi members even while his contemporary political priorities had shifted toward reconciliation.[3][11]

In a letter dated September 9, 1974, Yellin-Mor explained his political transformation in terms of the achievement of Jewish independence.[3] With independence secured, he considered the central task to be ensuring Israel’s continued existence through peace and historical reconciliation with its neighbors.[3] He wrote: “We can achieve [Israel’s acceptance as an indisputable fact] only through peace with our neighbors, through a historic reconciliation with them.”[3] His trajectory had taken him from Revisionism and support for a Greater Israel on both banks of the Jordan to advocacy of “two states for two peoples.”[3]

Yellin-Mor’s published writings included Lohamei Herut Yisrael: Anashim, Ra'ayonot, Alilot, translated as “People, Ideas, Deeds,” issued in 1975, and Shenot be-Terem, or “The Years Before,” published in 1990.[2] In addition to his work on Di Tat, Ha-Hazit, and Etgar, he edited a daily financial newspaper and wrote political columns and memoirs.[2][3] His writing therefore covered underground history, current political argument, and economic journalism across different stages of his career.[2][3]

His personal archive contains documents, meeting diaries, Lehi material, correspondence, photographs, manuscripts, interviews, and recordings.[12] It also preserves records of his post-statehood activity in left-wing and peace organizations, bringing together material from political phases that otherwise differed sharply in their objectives and methods.[12] The collection reflects his roles as an underground commander, political leader, editor, author, and thinker.[12]

Yellin-Mor died in Tel Aviv on February 18, 1980.[1][3] At his grave, his former Lehi colleague Yitzhak Shamir said: “The heart weeps for the great talent that did not find the right channel.”[3] The eulogy brought the relationship between the former underground colleagues into the account of his death, after their careers had followed different political paths.[3]

In a 2023 interview, his son Elisha characterized him as a public figure rather than a professional writer and described his later years as consistently left-wing.[13] A remembered encounter with the Lubavitcher Rebbe offered another perspective on the reception of his writing: Yellin-Mor, initially apprehensive because of their ideological and religious differences, asked why the Rebbe read him so avidly.[14] The Rebbe replied that if he read only people who agreed with him, he would read very little.[14]

His political and moral outlook, including his association with the Algerian underground, also became the subject of a chapter in a 2025 scholarly book on the history of the Israeli right.[15] Together with the preservation of his papers and memoirs, this later scholarly attention encompasses both his place in the struggle for Jewish independence and his subsequent involvement in the Israeli left and peace movement.[12][15]

The principal controversies surrounding Yellin-Mor concern Lehi’s methods and his responsibility as a member of its leadership, including the attempted approach to Nazi German representatives and decisions involving political assassination.[2][3] His leadership role must be distinguished from evidence of personal participation in particular attacks: the account attributing approval of Bernadotte’s assassination to the three leaders does not specify his individual operational involvement.[7] His later advocacy of territorial withdrawal and Palestinian statehood likewise represented a major departure from his earlier political positions.[3]

Accounts of his legal outcome after Bernadotte’s assassination differ. The Jewish Virtual Library says he was acquitted of complicity in the killing and convicted of membership in a terrorist organization, while Britannica says he was acquitted of murder but convicted of underground activities.[1][2] Encyclopedia.com instead states that he was convicted for the assassination.[8] The disagreement is consequential because imprisonment after the killing does not, by itself, establish a conviction for murder.[1][2]
