The Mir Yeshiva (, Yeshivas Mir), known also as The Mir, is an Orthodox Jewish yeshiva in Beit Yisrael, Jerusalem. With over 9,000 single and married students, it is the largest yeshiva in the world. Most students are from the United States, United Kingdom and Israel, with many from other parts of the world such as Belgium, France, Mexico, Switzerland, Argentina, Australia, Russia, Canada and Panama. History The yeshiva was founded in the small town of Mir (now in Belarus) in 1814, 1815 or 1817 by Rabbi Shmuel Tiktinsky. After his death, his oldest son Rabbi Avraham Tiktinsky was appointed Rosh Yeshiva. After a number of years, Rabbi Avraham died and his younger brother Rabbi Chaim Leib Tiktinsky succeeded him. Rabbi Chaim Leib would remain as Rosh Yeshiva for many decades. He was succeeded by his son, Rabbi Avrohom Tiktinsky, who brought Rabbi Eliyahu Boruch Kamai into the yeshiva. In 1903, Rabbi Kamai's daughter married Rabbi Eliezer Yehuda Finkel (Reb Leizer Yudel), son of Rabbi Nosson Tzvi Finkel (the Alter of Slabodka), who in time became the Rosh Yeshiva of the Mir. The yeshiva remained in that location until 1914. With the outbreak of World War I, the yeshiva moved to Poltava (now in Ukraine). In 1921, the yeshiva moved back to its original facilities in Mir, where it remained until based on secret parts of the Molotov-Ribbentrop Pact, Nazi Germany and the Soviet Union invaded Poland in 1939. Although many of the foreign-born students left when the Soviet army invaded from the east, the yeshiva continued to operate, albeit on a reduced scale, until the approaching Nazi armies caused the leaders of the yeshiva to move the entire yeshiva community to Keidan, Lithuania. The Yeshiva moved en masse on October 15 to Vilna in order to get out from under Russian rule and into then-free Lithuania. Russia had announced that it was returning Vilna to Lithuania. Until that was completed, they could go to Vilna with crossing a border. Establishment in Jerusalem Around this time, Rabbi Eliezer Yehuda Finkel traveled to Palestine to obtain visas for his students and reestablish the yeshiva in Eretz Yisrael, but these plans were interrupted by the outbreak of World War II. In 1944, Rabbi Finkel opened a branch of the yeshiva in Jerusalem with ten students, among them Rabbi Yudel Shapiro (later Rosh Kollel Chazon Ish), Rabbi Chaim Brim (later Rosh Yeshiva of
