Broadly defined, Religious Zionism is a movement that embraces the idea of Jewish national sovereignty, often in connection with the belief in the ability of the Jewish people to bring about a redemptive state through natural means, and often attributing religious significance to the modern State of Israel. The spiritual thinkers who started this stream of thought include Rabbi Zvi Hirsch Kalischer (1795–1874) and Rabbi Yitzchak Yaacov Reines (1839–1915). (This attitude is rejected by most Haredim—but not all, particularly the Hardal movement.) Thus, in this sense, Religious Zionism in fact encompasses a wide spectrum of religious views including Modern Orthodoxy.
