In the 19th and early 20th century, the majority of Jews rejected Zionism. The causes of this reaction varied — on the right, orthodox religious Jews (especially Haredi and Hasidic) believed that the re-establishment of a Jewish state in Israel was a task to be undertaken by the Messiah alone — Zionists, by attempting to hurry up the divine plan of redemption, were committing a sin. They pointed to various rabbinical passages which prohibited the return of Jews to Israel en masse prior to the coming of the Messiah. However, this rejection of Zionism was only one opinion within the conservative religious Jewish community with notable support coming from several prominent and senior Rabbis especially Rabbi Kook. On the left, progressive, secular and reform Jews wanted Jews to be accepted as members of the nations they were now living in, rather than attempting to form their own for themselves. These Jews often had commitments to liberal internationalism or socialism, and they saw Zionism as contrary to this.
