Israel Zangwill was a British author at the forefront of cultural Zionism during the 19th century, and was a close associate of Theodor Herzl. He later rejected the search for a Jewish homeland in Palestine and became the prime thinker behind the territorial movement.

Theodor Herzl was an Austro-Hungarian Jewish journalist, lawyer, writer, playwright and political activist who was the father of modern political Zionism. Herzl formed the Zionist Organization and promoted Jewish immigration to Palestine in an effort to form a Jewish state. Due to his Zionist work, he is known in Hebrew as Chozeh HaMedinah, lit. 'Visionary of the State'. He is specifically mentioned in the Israeli Declaration of Independence and is officially referred to as "the spiritual father of the Jewish State".
