A homeland for the Jewish people is an idea rooted in Jewish culture and religion. In the early 19th century, the Napoleonic Wars led to the idea of Jewish emancipation. This unleashed a number of religious and secular cultural streams and political philosophies among the Jews in Europe, covering everything from Marxism to Chassidism. Among these movements was Zionism as promoted by Theodore Herzl. In the late 19th century, Herzl set out his vision of a Jewish state and homeland for the Jewish people in his book Der Judenstaat. Herzl was later hailed by the Zionist political parties as the founding father of the State of Israel. In the Balfour Declaration of 1917, the United Kingdom became the first world power to endorse the establishment in Palestine of a "national home for the Jewish people." The British government confirmed this commitment by accepting the British Mandate for Palestine in 1922 (along with their colonial control of the Pirate Coast, Southern Coast of Persia, Iraq and from 1922 a separate area called Transjordan, all of the Middle-Eastern territory except the French territory). The European powers mandated the creation of a Jewish homeland at the San Remo conference of 19–26 April 1920. In 1948, the State of Israel was established.
The Jewish aspiration to return to Zion is part of Jewish religious thought that dates back to the destruction of the First Temple. However, the modern movement for the creation of a secular homeland within the confines of modern international law was perceived as a solution to the widespread persecution of Jews within Europe. This became the centerpiece of secular political Zionism. Anti-Semitism was not limited to Europe. The Zionist movement was preceded by several Jewish groups that had already popularized the move to Israel. For example, Israel ben Pereẓ of Polotsk and hundreds of other Jewish groups settled in Israel from Europe, developing communities in Jerusalem, Hebron and around much of the country. This was in addition to the already existing communities of Sephardi and Ashkenazim in Tiberias, Tsfat and across the rest of the Jewish "Holy Land". Zionists, however, worked within the existing international legal framework, obtaining international legal rights in 1922. They also armed and defended themselves.
