The First Aliyah, also known as the agriculture Aliyah, was a major wave of Jewish immigration (aliyah) to Ottoman Palestine between 1881 and 1903. Jews who migrated in this wave came mostly from Eastern Europe and from Yemen, stimulated by pogroms and violence against the Jewish communities in those areas. An estimated 25,000 Jews immigrated. Many of the European Jewish immigrants during the late 19th-early 20th century period gave up after a few months and went back to their country of origin, often suffering from hunger and disease.

Aliyah is the immigration of Jews from the diaspora to, historically, the geographical Land of Israel or the Palestine region, which is today chiefly represented by the State of Israel. Traditionally described as "the act of going up", moving to the Land of Israel or "making aliyah" is one of the most basic tenets of Zionism. The opposite action — emigration by Jews from the Land of Israel — is referred to in the Hebrew language as yerida. The Law of Return that was passed by the Israeli parliament in 1950 gives all diaspora Jews, as well as their children and grandchildren, the right to relocate to Israel and acquire Israeli citizenship on the basis of connecting to their Jewish identity.
