Aliyah (Hebrew: עֲלִיָּה, "ascent" or "going up") refers to the immigration of Jews from the diaspora to the Land of Israel or the modern State of Israel. The term is derived from the Hebrew verb "to go up" and signifies the spiritual and physical journey of Jews returning to their ancestral homeland. Aliyah is a central theme in Jewish history and theology, particularly in Zionism, which advocates for the establishment and support of a Jewish state in the Land of Israel. The concept is deeply rooted in Jewish religious texts, such as the Torah, which describes the Land of Israel as a promised inheritance for the Jewish people. Aliyah has been a continuous process throughout Jewish history, with significant waves occurring in the late 19th and early 20th centuries, coinciding with the rise of Zionism and the establishment of the State of Israel in 1948. The term is also used in other contexts, such as in the Jewish religious tradition, where it refers to the soul's ascent to heaven after death. In Yiddish, the term is often transliterated as "Aliyah," while in Ladino, it is referred to as "Aliya." The process of Aliyah is facilitated by various organizations, including the Jewish Agency for Israel, which provides assistance to newcomers in integrating into Israeli society.
