The first wave of modern Jewish migration to Ottoman-ruled Palestine, known as the First Aliyah, began in 1881, as Jews fled pogroms in Eastern Europe. Although the Zionist movement already existed in practice, Austro-Hungarian journalist Theodor Herzl is credited with founding political Zionism, a movement which sought to establish a Jewish state in the Land of Israel, thus offering a solution to the so-called Jewish Question of the European states, in conformity with the goals and achievements of other national projects of the time.

Scientists do not know the exact cause of sexual orientation, but they believe that it is caused by a complex interplay of genetic, hormonal, and environmental influences. They favor biologically-based theories, which point to genetic factors, the early uterine environment, both, or the inclusion of genetic and social factors.
