1955 in Israel

Israel entered 1955 still navigating the consequences of the mass immigration wave of 1948–1952, which brought some 750,000 immigrants. Population growth during the state's first decade averaged approximately 8 percent annually, combining immigration with natural growth of about 2.5 percent per year.[6] A demographic table lists Israel's 1955 population as approximately 1,590,500 Jews and 198,600 non-Jews, for a total of roughly 1,789,100.[2] A contemporaneous report placed the total population on May 1 at 1,745,577, including 1,550,958 Jews, or 88.9 percent of the population, and ranked Israel third among countries with the largest Jewish populations.[3]

The demographic structure reflected rapid immigration and natural increase: fertility averaged more than four births per woman, the crude birth rate stood at approximately 30 per 1,000, and life expectancy was roughly 60 years.[6] Between 1950 and 1963, the share of children in the population rose by 4.7 percentage points while the working-age share declined from 55.6 percent to 49.4 percent, increasing the burden on the state's absorptive capacity.[6] At the beginning of 1955, fewer than 80,000 people remained in maabaroth and special camps, down from 230,000 at the end of 1951. The foreign-trade deficit had narrowed from $342 million in 1951 to approximately $190 million in 1954, and inflation had been brought under control.[7]

The security environment was equally challenging. Arab states had combined military allocations estimated at $500 million, more than Israel's entire national budget, while border incidents, infiltration, and marauding remained persistent concerns.[7] The British evacuation of the Suez Canal zone and anticipated Western arms supplies to Arab states heightened Israeli anxiety about renewed Arab-Israeli war.[7] Israel was also excluded from the Baghdad Pact signed by Turkey and Iraq on February 24, which it viewed as politically and potentially militarily damaging. Israeli requests to Washington for a defense treaty and security guarantees met American concern about being drawn into a regional conflict.[1]

The Lavon Affair cast a long shadow over Israeli politics at the year's outset. It arose from a failed 1954 Israeli intelligence operation in Egypt involving plans to plant bombs in civilian institutions, which led to the arrest and trial of eleven Egyptian Jews who had served as Israeli agents.[8] On January 31, 1955, Moshe Marzouk and Shmuel Azar were executed after the Cairo trial. Two other victims were Eliahu Karmona, who died under torture, and Max Bineth, whom Egyptian authorities said had taken his own life.[1] The Knesset held a formal debate on the trial and executions that day.[9]

The political consequences in Israel were severe. Pinhas Lavon was forced to resign as defense minister, and on February 21 David Ben-Gurion assumed the defense portfolio under Prime Minister Moshe Sharett, returning to government after retiring to Kibbutz Sde Boker in 1953.[8] An investigative committee was unable to reach a clear conclusion about whether Lavon or Colonel Binyamin Givli had authorized the sabotage operation, and Givli was removed from Intelligence Operations.[8] The affair affected Israeli politics for nearly a decade and formed part of the charged political background of 1955.[8]

The Knesset convened on February 21 to debate the ministerial reshuffle caused by Lavon's resignation and Ben-Gurion's return.[9] Sharett remained prime minister but now governed alongside a defense minister with a different strategic emphasis. Sharett prioritized diplomatic stabilization and de-escalation, while Ben-Gurion placed greater weight on military power and deterrence.[10][1]

The defining military event of the first half of 1955 was Operation Black Arrow on February 28. Egyptian infiltrators had attacked a military installation near Rishon LeZiyyon on February 23 and killed a cyclist near Rehovot on February 26. Israeli forces subsequently entered the Egyptian-controlled Gaza Strip, attacking an Egyptian Army camp near Gaza City, a pumping station, and a train station, and destroying Egyptian military headquarters.[1][11] The Israeli archival account reports 38 Egyptians and 8 Israelis killed. The U.S. diplomatic record gives the Egyptian toll as 37 armed-forces personnel and 2 civilians killed, with another 30 military personnel and 2 civilians wounded.[1][12]

The international response was sharply critical of Israel. The Egypt-Israel Mixed Armistice Commission found Israel responsible for the attack, and on March 29 the United Nations Security Council unanimously adopted Resolution 106. The resolution stated that the operation had been planned by Israeli authorities, condemned it as a violation of the cease-fire and armistice obligations, and called on Israel to prevent similar actions.[13][12] Egypt characterized the operation as "violent and premeditated" aggression. Israel submitted a counter-complaint alleging Egyptian attacks, raids from Egyptian-controlled territory, blockade measures, hostile propaganda, and refusal to negotiate a transition from armistice to peace.[12]

The operation's effects extended beyond the immediate exchange. It provoked large protests in the Gaza Strip, where demonstrators demanded weapons and the establishment of a Palestinian national guard trained and authorized by the Egyptian army.[11] Egypt responded by establishing the Palestinian National Guard, known in Arabic as al-Haras al-Watani. It reached a peak strength of 500 fighters, was trained and equipped by the Egyptian military, and was later redefined as a Palestinian battalion within the Egyptian army.[11] A commando unit led by Lieutenant Colonel Mustafa Hafez was formed from its recruits and eventually reached approximately 400 fedayeen, trained in sabotage, infiltration, and intelligence.[11]

UN Truce Supervision Organization Chief of Staff Major General E. L. M. Burns reported on March 17 that repeated minor incidents had created tension along the armistice line. He identified infiltration from Egyptian-controlled territory as one main, though not the only, cause.[12] Burns proposed joint patrols, agreements between local commanders, barbed-wire obstacles in selected areas, and the deployment of regular soldiers at border outposts. He noted that infiltration might be reduced to an occasional nuisance so long as large numbers of impoverished refugees remained along Israel's border.[12] The United States acknowledged that an Egyptian outpost had fired on an Israeli jeep on May 30 but urged Israeli forces to stop actions it considered provocative and cooperate with UNTSO, arguing that retaliatory raids did not reduce border tension.[14]

Running concurrently with the Gaza escalation was the resolution of the Bat Galim affair. Egyptian authorities had seized the Israeli-flag ship at the southern end of the Suez Canal in September 1954. Egypt released the crew on January 1, 1955, and indicated its intention to release the vessel.[15] On January 4 and 13, the UN Security Council continued its consideration of the case. The United States, United Kingdom, France, Brazil, Belgium, Peru, and New Zealand rejected Egypt's interpretation of the Constantinople Convention and maintained that its restrictions on Israeli shipping conflicted with the Security Council's 1951 resolution on freedom of passage through the canal.[15] Discussion concluded on January 13, when the Council president affirmed that the 1951 resolution remained in force.[15]

Israel's diplomatic year encompassed three broad phases identified in the U.S. Foreign Relations record: Operation Alpha, a joint American-British effort to develop an Arab-Israeli peace settlement, from January through late August; the consequences of the Egyptian-Czechoslovak arms deal from late August through mid-November; and American consideration of financing for the Aswan High Dam from mid-November through year's end.[16] Israel pursued security guarantees and military assistance from the United States, Britain, France, and Turkey, although American officials expressed reservations about a formal defense treaty.[1]

A milestone in Israel's relationships outside the immediate region came on May 29, when Burmese Prime Minister U Nu arrived in Israel for what was described as the first official visit by a foreign head of government. The visit formed part of a broader Israeli effort to develop ties with Asian states, including Burma, India, Japan, and China.[1]

The election to the Third Knesset was held on July 26, 1955. It recorded 853,219 valid ballots among 1,057,609 eligible voters in a population of approximately 1,748,000, producing a turnout of 80.7 percent.[17][18]

Mapai remained the largest party with 274,735 votes, or 32.2 percent, and 40 seats, although it lost 4 seats compared with the previous Knesset.[17][19] The most dramatic change was Herut's surge: its vote increased from 45,651 to 107,190, and its representation rose from 8 to 15 seats.[17][19] The General Zionists lost 7 seats and fell to 13.[17][19] Other parties winning seats included the United Religious Front with 11, Ahdut Ha'avodah with 10, Mapam with 9, the Religious Torah Front and Maki with 6 each, and the Progressive Party with 5.[17] An electoral-law change requiring at least 1 percent of the vote eliminated two smaller parties from the chamber.[19]

The political transition followed a period of conflict between Sharett and Ben-Gurion over diplomacy, military retaliation, and governmental control of border operations.[1] Sharett resigned in June after no-confidence motions connected to a judicial controversy, and elections followed the next month.[19]

Nearly four months passed before the post-election coalition was assembled. It included Mapai, Ahdut Avoda, Mapam, the Mizrachi/Hapoel Hamizrachi bloc—which merged on August 9 to become the National Religious Party—and the Progressives.[19] Sharett's Fifth Government gave way on June 29 to a Sixth Government in which he remained prime minister and foreign minister and Ben-Gurion served as defense minister.[4] The Seventh Government, sworn in on November 3, installed Ben-Gurion as prime minister and defense minister, while Sharett remained foreign minister alongside Levi Eshkol as finance minister and Golda Meir as labor minister.[5] Sharett and Ben-Gurion held similar positions on immigration and economic strategy but continued to differ over relations with the Arab world, a conflict that contributed to Sharett's resignation in 1956.[10]

On September 28, 1955, Egypt announced a major arms agreement with Czechoslovakia, widely understood as a Soviet-bloc transaction. Israel characterized the deal as a hostile development that undermined the regional balance of power.[1] The United States considered it one of the most serious developments since the Second World War but stated that it did not intend to enter an arms race.[1]

Israel sought to compensate through diplomatic and procurement channels, approaching the United States, France, Britain, and other Western states for weapons. France emerged as its principal source of support.[1] Israeli officials also discussed extensive military action as one possible response to the changing strategic balance.[1]

In an August 31 public statement, Nasser declared: "There will be no peace on Israel's border because we demand vengeance, and vengeance is Israel's death."[20] Egyptian-directed fedayeen terrorists, trained in sabotage, infiltration, and intelligence, launched an infiltration wave in August 1955. Approximately 200 entered Israel in small groups with missions to assassinate Jews and gather intelligence.[11] The Soviet bloc also began its first arms sales to Syria during 1955.[21]

In the early morning of December 12, 1955, the IDF carried out Operation Olive Leaves, also known as Operation Kinneret, against Syrian positions near the northeastern shore of the Sea of Galilee. The operation occurred amid a prolonged dispute over demilitarized areas and Syrian interference with Israeli fishing.[1] Israeli forces attacked a series of outposts along the northern border and the lakeshore. The foreign-policy volume reports that more than 50 Syrian soldiers were killed and approximately 30 were taken prisoner.[1]

The action caused immediate diplomatic damage. Moshe Sharett, still foreign minister, and other officials protested that it had not been adequately coordinated with the political leadership or Foreign Ministry.[1] The United States and Britain criticized the operation and linked it to deliberations over arms supplies to Israel, illustrating the continuing friction between military command and diplomatic oversight.[1]

Additional Israeli military actions during the autumn included operations in the Nitzana/Auja demilitarized zone on September 21, at Kuntilla on October 28, and again in the Nitzana zone on November 3.[1] The armistice agreement designated the Nitzana area as demilitarized while leaving sovereignty unresolved, an ambiguity that generated repeated confrontations. Israeli-Egyptian understandings were reached in September regarding troop withdrawals and border marking.[1]

Immigration accelerated in 1955 after the slower years of 1952–1954. A U.S. diplomatic memorandum counted 36,227 immigrants in 1955, compared with 17,485 in 1954.[22] A broader absorption table, which included tourists who subsequently settled, gave a 1955 total of 37,478.[23] Across 1955–1957, most immigrants came from Morocco, Tunisia, and Poland, and total immigration reached 162,308. The renewed movement accompanied economic recovery, growth in industry and agriculture, new development projects, and political changes in countries of origin.[23]

Israel's 1955 immigration program planned to receive at least 30,000 Jews from North Africa—approximately 22,000 from Morocco and 8,000 from Tunisia—plus at least 5,000 from other areas. Priority was given to communities in outlying districts where French control was weak and Jewish life and property were considered vulnerable.[7] Restrictions on Jewish emigration from Morocco were removed in July, and Israel set an operational target of approximately 2,500 Moroccan emigrants per month. Approximately 70,000 Moroccan Jews left during 1955–1957, and more than 15,000 departed for Israel between January and July 1955.[1]

The Jewish Agency's Youth Aliyah program planned to receive approximately 1,250 young immigrants, mostly from North Africa, while selecting 4,400 youths from maabaroth and immigrant settlements for vocational training. Another 1,880 were to be served through special courses and pre-vocational centers, bringing the expected total to approximately 16,000 young people, 2,500 more than in 1954.[7]

The plan to close all maabaroth by the end of 1955 was deferred indefinitely because resources were redirected toward receiving North African immigrants.[7] Tens of thousands of immigrants were therefore expected to spend another winter in temporary settlements. Approximately 80,000 people had remained in maabaroth and special camps for the aged and disabled at the end of 1954, and renewed immigration made rapid closure impracticable.[7] The founding of Dimona in 1955 by 36 immigrant families from Morocco and Tunisia exemplified the strategy of dispersing newcomers into underdeveloped southern regions.[21]

The Yarkon-Negev irrigation pipeline opened on July 19, 1955, but the cited archival document contains two different sets of project figures.[7] Its retrospective account describes a 63-mile, 66-inch line from Rosh Ha'ayin near Tel Aviv to Gevulot in the northern Negev, built over three years by approximately 2,000 workers and 60 engineers at a cost of 45 million Israeli pounds. It says water was raised more than 750 feet and that the first stage could carry 50 billion gallons annually, eventually enabling irrigation of an additional 40,000 acres.[7]

An earlier budget discussion in the same document projected a 70-mile, 66-inch pipeline from Rosh Ha'ayin to Mivtachim, costing $42 million and carrying 100 million cubic meters annually.[7] Despite the conflicting project measurements, the document consistently presents the scheme as essential to agricultural expansion: 57 percent of Israel's arable land lay in the south, while many of its streams and rivers were in the north.[7]

On August 7, 1955, Bar-Ilan University was founded by Professor Pinkhos Churgin, an American Orthodox rabbi and educator who served as its first president from 1955 to 1957.[24] The institution was conceived as an Israeli university combining Torah and general studies, following the model of Yeshiva University in the United States.[24] Its first academic year began on September 20 in temporary buildings, with 90 students enrolled in 34 courses across eight classrooms and two laboratories. Twenty-three faculty members taught in four departments.[24]

At the opening ceremony, Churgin declared that Bar-Ilan would "demonstrate that Judaism is not a cloistered way of life, removed from scientific investigation and worldly knowledge."[24] The institution represented a vision of higher education in which Jewish religious tradition and modern academic inquiry would coexist, and it later grew into one of Israel's largest universities.[24]

On July 27, 1955, one day after the Knesset election, Bulgarian fighter aircraft shot down El Al Flight 402 while it was traveling toward Israel after straying from its flight path.[1][25] All 58 people aboard were killed.[1] Israel subsequently protested to Bulgaria, sought access for an Israeli investigation committee, and requested compensation for the aircraft and casualties.[1] The incident was later debated during the Third Knesset term.[25]

On September 26, 1955, oil was discovered at Heletz, a moshav in southern Israel.[26] The Heletz field became the site of Israel's first successful oil well and was estimated to contain approximately 94.4 million barrels.[26] Exploratory drilling at the site had begun in 1947, and 33 wells were completed by the end of 1957. Oil production began in 1960.[26]

An Israeli government publication characterizes 1955 as a year in which deteriorating border security, Israeli retaliatory operations, weakening international standing, exclusion from Western Middle Eastern defense arrangements, and the absence of a reliable great-power alliance combined to create a decisive turning point.[1] The Czech-Egyptian arms deal brought the Arab-Israeli conflict more directly into the Cold War and formed part of the chain of developments culminating in the 1956 Suez-Sinai Campaign.[1]

The political transition from Sharett to Ben-Gurion also had lasting consequences. Sharett prioritized diplomatic stabilization and proportionate responses, while Ben-Gurion placed greater emphasis on military strength and deterrence through retaliation.[10][1] Their disagreements continued after Ben-Gurion became prime minister, and Sharett resigned as foreign minister in 1956.[10]

A Jewish Review of Books discussion of Anita Shapira's historical work quotes the assessment that "1955 was a year in which the status quo created by the armistice agreements became shaky."[27] Scholarly debate continues over the relative importance of Operation Black Arrow in Egypt's subsequent policy. Some historians argue that the Gaza raid critically changed Nasser's posture and accelerated his turn toward the Soviet bloc, while others attribute Egypt's intensified engagement primarily to Nasser's pan-Arab aspirations.[27]

Beyond security and diplomacy, the year included major nation-building developments. Bar-Ilan University was founded and the Yarkon-Negev pipeline opened.[24][7] Oil was discovered at Heletz, and large-scale immigration resumed.[26][23] Dimona's establishment by North African immigrant families also reflected the state's continuing settlement and demographic-dispersal policies.[21]

The February 28 Gaza operation is presented differently across the sources. Israeli archival material connects its planning to Egyptian infiltrations and attacks during the preceding days.[1] The UN Security Council resolution and U.S. diplomatic record characterize it as a planned Israeli attack that violated the armistice.[13][12]

Casualty accounts also differ. The Begin-Sadat Center gives 37 Egyptian soldiers and one civilian killed, alongside 8 Israeli fatalities.[11] The U.S. diplomatic record gives 37 Egyptian military personnel and 2 civilians killed.[12] The Israeli foreign-policy volume reports 38 Egyptians and 8 Israelis killed.[1]

The interpretation of Operation Black Arrow's consequences for Egyptian policy remains contested. Some scholars hold that it provoked Nasser's turn toward Soviet-bloc arms and accelerated regional escalation, while others treat his pan-Arab ambitions and opposition to Western alliances as more fundamental drivers.[27] The Lavon Affair likewise remained disputed because investigative bodies did not establish definitively whether Lavon or Givli authorized the original operation.[8] Interpretations of the Sharett-Ben-Gurion conflict also vary, but the sources consistently identify a substantive disagreement over diplomacy, retaliation, and the role of military power in Israeli policy.[10][1]
