Israeli Prime Minister David Ben-Gurion orders the expulsion of Palestinians from the towns of Lod and Ramla.

The 1948 Palestinian exodus from Lydda and Ramle, also known as the Lydda Death March, was the expulsion of 50,000 to 70,000 Palestinian Arabs when Israeli troops captured the towns in July that year. The military action occurred within the context of the 1948 ArabIsraeli War. The two Arab towns, lying outside the area designated for a Jewish state in the UN Partition Plan of 1947, and inside the area set aside for an Arab state in Palestine, subsequently were transformed into predominantly Jewish areas in the new State of Israel, known as Lod and Ramla.The exodus, constituting "the biggest expulsion of the war", took place at the end of a truce period, when fighting resumed, prompting Israel to try to improve its control over the Jerusalem road and its coastal route which were under pressure from the Jordanian Arab Legion, Egyptian and Palestinian forces. From the Israeli perspective, the conquest of the towns, designed, according to Benny Morris, "to induce civilian panic and flight", averted an Arab threat to Tel Aviv, thwarted an Arab Legion advance by clogging the roads with refugees the Yiftah Brigade was ordered to strip them of "every watch, piece of jewelry, or money, or valuables" to force the Arab Legion to assume an additional logistical burden with the arrival of masses of indigent refugees that would undermine its military capacities, and helped demoralise nearby Arab cities. On 10 July, Glubb Pasha ordered the defending Arab Legion troops to "make arrangements ... for a phony war". The next day, Ramle surrendered immediately, but the conquest of Lydda took longer and led to an unknown number of deaths; the Palestinian historian Aref al-Aref, the only scholar who tried to draw up a balance sheet for the Palestinian losses, estimated 426 Palestinians died in Lydda on 12 July, of which 176 in the mosque and 800 overall in the fighting. Israeli historian Benny Morris suggests up to 450 Palestinians and 910 Israeli soldiers died.Once the Israelis were in control of the towns, an expulsion order signed by Yitzhak Rabin was issued to the Israel Defense Forces (IDF) stating, "1. The inhabitants of Lydda must be expelled quickly without attention to age....". Ramle's residents were bussed out, while the people of Lydda were forced to walk miles during a summer heat wave to the Arab front lines, where the Arab Legion, Transjordan's British-led army, tried to provide shelter and supplies. A number of the refugees died during the exodus from exhaustion and dehydration, with estimates ranging from a handful to a figure of 500.The events in Lydda and Ramle accounted for one-tenth of the overall Arab exodus from Palestine, known in the Arab world as al-Nakba ('the catastrophe'). Some scholars, including Ilan Papp, have characterised what occurred at Lydda and Ramle as ethnic cleansing. Many Jews who came to Israel between 1948 and 1951 settled in the refugees' empty homes, both because of a housing shortage and as a matter of policy to prevent former residents from reclaiming them. Ari Shavit noted that the "events were crucial phase of the Zionist revolution, and they laid the foundation for the Jewish state."

David Ben-Gurion ( ben GOOR-ee-ən; Hebrew: דָּוִד בֶּן-גּוּרִיּוֹן [daˈvid ben ɡuʁˈjon] (listen); born David Grün; 16 October 1886 – 1 December 1973) was the primary national founder of the State of Israel and the first Prime Minister of Israel. Adopting the name of Ben-Gurion in 1909, he rose to become the preeminent leader of the Jewish community in British-ruled Mandatory Palestine from 1935 until the establishment of the State of Israel in 1948, which he led until 1963 with a short break in 1954–55.

Ben-Gurion's passion for Zionism, which began early in life, led him to become a major Zionist leader and executive head of the World Zionist Organization in 1946. As head of the Jewish Agency from 1935, and later president of the Jewish Agency Executive, he was the de facto leader of the Jewish community in Palestine, and largely led its struggle for an independent Jewish state in Mandatory Palestine. On 14 May 1948, he formally proclaimed the establishment of the State of Israel, and was the first to sign the Israeli Declaration of Independence, which he had helped to write. Ben-Gurion led Israel during the 1948 Arab–Israeli War, and united the various Jewish militias into the Israel Defense Forces (IDF). Subsequently, he became known as "Israel's founding father".Following the war, Ben-Gurion served as Israel's first prime minister and minister of defense. As prime minister, he helped build the state institutions, presiding over national projects aimed at the development of the country. He also oversaw the absorption of vast numbers of Jews from all over the world. A centerpiece of his foreign policy was improving relationships with the West Germans. He worked with Konrad Adenauer's government in Bonn, and West Germany provided large sums (in the Reparations Agreement between Israel and West Germany) in compensation for Nazi Germany's confiscation of Jewish property during the Holocaust.In 1954 he resigned as prime minister and minister of defense but remained a member of the Knesset. He returned as minister of defense in 1955 after the Lavon Affair and the resignation of Pinhas Lavon. Later that year he became prime minister again, following the 1955 elections. Under his leadership, Israel responded aggressively to Arab guerrilla attacks, and in 1956, invaded Egypt along with British and French forces after Egypt nationalized the Suez Canal during the Suez Crisis.

He stepped down from office in 1963, and retired from political life in 1970. He then moved to Sde Boker, a kibbutz in the Negev desert, where he lived until his death. Posthumously, Ben-Gurion was named one of Time magazine's 100 Most Important People of the 20th century.
