Bilu (Hebrew: ביל"ו; also Palestine Pioneers) was a Jewish movement of the late 19th century, fueled predominantly by the immigration of Russian Jews, whose goal was the agricultural settlement of the Land of Israel. Its members were known as Bilu'im, and the movement sought to inspire Jews to migrate to Ottoman Palestine. The Bilu'im rejected progressive notions such as Emancipation and assimilation as viable options for Jewish survival. The movement collapsed as a result of the challenging farming conditions in Palestine and a lack of funding to sustain the settlers.
