Aliyah

• 1. Introduction

  ›

  Aliyah is the Hebrew word for "ascent" or "going up," and for thousands of years it has described a singular human movement: Jews from every corner of the world leaving their homes and traveling to the Land of Israel. In the late 19th century, 99.7 percent of the world's Jews lived outside that land. Today, Israel and the Israeli-occupied territories hold approximately 42.9 percent of the world's Jewish population. That transformation, accomplished across just a few generations, is one of the most dramatic demographic shifts in modern history. How did it happen? Who were the people who came, and what drove them? What did it cost, and what did it build? The story of aliyah stretches from a biblical patriarch named Abraham arriving in Canaan around 1800 BC, to Ukrainian Jews crossing into Israel in 2022 after Russia's invasion. At its heart is a single repeating question: what does it mean to go home?

• 2. The Word and Its Weight

  ›

  Jerusalem sits at roughly 750 meters above sea level. For Jews who lived in Egypt's Nile Delta or on the plains of Babylonia, a journey to Jerusalem was literally an uphill climb. That physical fact gave rise to a spiritual metaphor that has endured for millennia. To travel toward Jerusalem was to ascend, in both the geographic and the metaphysical sense.

  The term aliyah carries a legal counterpart in the Law of Return, passed by the Israeli parliament in 1950. That law grants all diaspora Jews, along with their children and grandchildren, the right to relocate to Israel and acquire citizenship based on their Jewish identity. Someone who makes aliyah is called an oleh if male, or an olah if female; the plural forms are olim and olot. The opposite of aliyah is yerida, meaning "descent" or "going down." Since 2024, yerida has outpaced aliyah, giving Israel its first period of net negative migration.

  The widespread use of aliyah as a term for ideologically motivated Jewish immigration was largely shaped by Arthur Ruppin's 1930 work Soziologie der Juden. Sociologist Aryeh Tartakower later defined it even more broadly, as immigration for the good of the community, regardless of where the destination happened to be. Both definitions placed intention at the center of the concept. Aliyah was not simply moving; it was a statement about who you were and where you believed you belonged. The medieval sage Nachmanides included making aliyah in his enumeration of the 613 commandments, and the Sifre text holds that living in Eretz Yisrael is as weighty as all other commandments combined.

• 3. Waves Before Zionism

  ›

  In 1211, a group remembered as the "aliyah of the three hundred rabbis" brought notable French and German scholars, including Samson of Coucy, Joseph ben Baruch, and Samson ben Abraham of Sens, to Palestine. The account is recorded in the Shebet Yehudah, though scholars doubt the round number of three hundred, and Jonathan ben David ha-Cohen, mentioned in the same account, had already died in 1205. Few of the settlers' descendants survived the violence of the Crusader invasion in 1229 and the subsequent expulsion by Muslims in 1291.

  In the 10th century, leaders of the Karaite Jewish community, living mostly under Persian rule, urged their followers to settle in Eretz Yisrael. The Karaites built their own quarter in Jerusalem, on the western slope of the Kidron Valley. Evidence from this period shows a steady stream of Jewish pilgrims arriving, mainly during the month of Tishrei around the Sukkot holiday. The expulsions of Jews from England in 1290, France in 1391, Austria in 1421, and Spain in 1492 each sent waves of refugees eastward toward the Holy Land, many interpreting their displacement as a sign of approaching messianic redemption.

  Moses ben Joseph di Trani, born in Salonika in 1490, made aliyah and became the rabbi of Safed, where he died in 1580. Di Trani argued, against earlier rabbinical voices, that the journey to Palestine was not dangerous given the relative peace between Christian Europe and the Islamic world at that time. In the 1560s, Gracia Mendes and Joseph Nasi obtained a concession from the sultan to permit Jews to settle in Safed and Tiberias. By the 18th century, Judah HeHasid and his followers arrived in Jerusalem in 1700, and Hayyim ben Jacob Abulafia and his group settled in Tiberias the same year. In 1808, hundreds of disciples of the Gaon of Vilna, known as the Perushim, settled in Tiberias and Safed, forming the core of the Old Yishuv in Jerusalem.

• 4. The Zionist Waves

  ›

  Between 1882 and 1903, approximately 35,000 Jews arrived in Ottoman Palestine, joining a pre-existing Jewish population of 20,000-25,000. They called themselves Hovevei Tsiyon, enthusiasts for Zion, and they established agricultural communities including Rishon LeZion and Zikhron Ya'akov. Petah Tikva had already been founded in 1878. In 1882, Yemenite Jews settled in the Arab village of Silwan, southeast of the walls of the Old City of Jerusalem.

  The Second Aliyah, from 1904 to 1914, brought 35,000-40,000 more Jews, the vast majority from the Pale of Settlement. Eastern European immigrants steeped in socialist ideals founded the first kibbutz, Degania Alef, in 1909. That same year, a new suburb of Jaffa called Ahuzat Bayit was established; it eventually grew into the city of Tel Aviv. Ben Gurion later estimated that nine out of ten who came during this period eventually left.

  The Third Aliyah brought 40,000 halutzim, or pioneers, between 1919 and 1923 in the wake of the First World War. They drained the marshes of the Jezreel Valley and the Hefer Plain, and built national institutions including the Histadrut labor federation and the Haganah paramilitary organization. Between 1924 and 1929, the Fourth Aliyah delivered 82,000 Jews, many fleeing antisemitism in Poland; about 23,000 of them eventually departed. The Fifth Aliyah, running from 1929 to 1939, brought 250,000 people, 174,000 of them arriving between 1933 and 1936 as Nazi rule tightened in Germany. German refugee architects introduced the Bauhaus style, resulting in Tel Aviv's White City, which holds the highest concentration of International Style architecture anywhere in the world. The Palestine Philharmonic Orchestra was founded during this period as well. By 1940, the Jewish population of Palestine had reached 450,000.

• 5. Aliyah Bet and the Escape from Europe

  ›

  The British White Paper of 1939 capped Jewish immigration to Mandatory Palestine at 75,000 people over five years. That quota, issued as the Holocaust was already under way in Europe, forced a clandestine network into existence. It became known as Aliyah Bet, or secondary immigration, organized primarily by the Mossad Le'aliyah Bet and also by the Irgun.

  Most of the illegal immigration moved by sea. After the war, an organization called Bricha, meaning escape, operated across Eastern Europe. In 1946, Poland was the only Eastern Bloc country that allowed Jews to leave for Mandate Palestine without visas or exit permits. More than 4,500 survivors sailed from the French port of Sète aboard a ship originally named President Warfield, later renamed Exodus. The British intercepted them, turned the ship back from Haifa, and forced the passengers ashore in Hamburg. Despite British efforts to stop this movement, some 110,000 Jews reached Palestine during the 14 years Aliyah Bet operated.

  In 1945, reports of the Holocaust's six million Jewish dead galvanized Jews inside Palestine, and illegal immigration escalated. Shortly after the Nazis came to power years earlier, they had negotiated what became known as the Ha'avara or Transfer Agreement with the Jewish Agency, under which 50,000 German Jews and roughly 100 million dollars' worth of their assets would be moved to Palestine. That arrangement, morally contested, helped bring a significant number of German Jews out before the extermination machinery accelerated. The legal framework the Zionist historians used to periodize all this immigration was first codified by sociologist David Gurevich in his 1944 work The Jewish Population of Palestine.

• 6. Mass Immigration After 1948

  ›

  When Israel declared independence in May 1948, the Jewish population stood at 650,000. By the end of 1951, that number had more than doubled. In 1949, a single year produced 249,954 new immigrants, the largest yearly intake ever recorded. The period is called kibbutz galuyot, the ingathering of exiles.

  Special operations ran to rescue communities judged to be in acute danger. Operation Magic Carpet, also known as Operation On Wings of Eagles from a verse in Exodus 19:4, airlifted nearly the entire Jewish community of Yemen, about 49,000 people, between 1949 and 1950. Operation Ezra and Nehemiah brought approximately 120,000 Iraqi Jews to Israel. Operation Goshen smuggled Egyptian Jews out of Egypt. Nearly the entire Jewish community of Libya left for Israel around this time, and clandestine aliyah from Syria continued for decades, since the Syrian government formally prohibited Jewish emigration.

  The logistics were staggering. By the end of 1950, roughly 93,000 immigrants were housed in 62 transit camps called ma'abarot. When people left the camps, they received a ration card, an identity card, a mattress, a pair of blankets, and between 21 and 36 dollars in cash. Israel built 260 new settlements and 78,000 housing units to accommodate the population. Austerity rationing governed daily life until 1953, when a reparations agreement with West Germany began channeling foreign capital into the Israeli economy. The last ma'abarot closed in 1963. Between 1952 and 1964, around 240,000 North African Jews came to Israel, many fleeing nationalist upheavals in Morocco, Tunisia, Algeria, and Egypt.

• 7. Jews from the Soviet World

  ›

  From Israel's establishment in 1948 until the Six-Day War in 1967, only about 22,000 Soviet Jews managed to reach Israel. The Soviet system required a formal petition from a relative abroad before any emigration application could begin, and refusals were common. Applicants typically had to quit their jobs first, leaving them vulnerable to criminal charges of social parasitism. Israel set up a liaison group called Lishkat Hakesher in the early 1950s to maintain contact with Jews behind the Iron Curtain.

  The Six-Day War of 1967 changed the dynamic. Soviet state-sponsored antisemitism intensified, while at the same time the Israeli military victory stirred Zionist feeling among assimilated Jews who had long since given up Hebrew culture. The Dymshits-Kuznetsov hijacking affair and the international outcry that followed pushed Soviet authorities to raise emigration quotas. In the years 1960-1970, only 4,000 people were allowed to leave; in the following decade, the number rose to 250,000. By 1989, a record 71,000 Soviet Jews received exit permits in a single year, though only 12,117 of them chose to go to Israel.

  That same year, the United States ended its policy of automatically granting Soviet Jews refugee status, and Mikhail Gorbachev lifted restrictions on Jewish emigration. The Soviet Union collapsed in 1991. In the years that followed, roughly one million people from the former Soviet Union immigrated to Israel, including approximately 240,000 who were not Jewish under rabbinical law but qualified under the Law of Return. In 2014, aliyah from the former Soviet states rose 50 percent compared to the previous year, with some 11,430 immigrants, about 43 percent of all new arrivals. The wave from Russia that began after 2014 acquired the informal name "cheese aliyah," after foreign cheese disappeared from Russian shops due to the government's counter-sanctions policy. Following the 2022 Russian invasion of Ukraine, Israel launched an "Immigrants Come Home" operation; by June 2022, more than 25,000 people had arrived from Ukraine, Russia, Belarus, and Moldova.

• 8. Yom HaAliyah

  ›

  On the 10th of the Hebrew month of Nisan, according to the Book of Joshua, Joshua and the Israelites crossed the Jordan River at Gilgal into the Promised Land, carrying the Ark of the Covenant. God commanded that twelve stones be erected, engraved with the text of the Torah, representing the twelve tribes. That crossing is considered the first documented mass aliyah.

  A modern holiday, Yom HaAliyah, began in 2009 as a grassroots initiative in Tel Aviv led by young immigrants, or olim, organized by the TLV Internationals group of the Am Yisrael Foundation. On the 21st of June 2016, the Twentieth Knesset voted to codify the holiday into law, adding it to the Israeli national calendar. The bill was co-sponsored by Knesset members from multiple parties in an unusual instance of cross-spectrum cooperation between opposition and coalition. The holiday falls annually on the 10th of Nisan, and is also observed in Israeli schools on the 7th of Cheshvan. The opening clause of the Yom HaAliyah Law states that the holiday exists to recognize the importance of Jewish immigration to the Land of Israel as the basis for the existence of Israel, its development, and its design as a multicultural society. The decision to anchor a 21st-century national holiday to a biblical date that stretches back to the Book of Joshua captures, in one gesture, the full arc of the concept the holiday celebrates.
