Before 1905 some Zionist leaders took seriously proposals for Jewish homelands in places other than the Land of Israel. Theodor Herzl hoped for a Jewish homeland in the Land of Israel but recognized that global events demanded an immediate solution to the Jewish problem, in Russia at least, even if that solution required Jewish refugees to settle outside of Eretz Israel. Theodor Herzl's "Der Judenstaat" argued for a Jewish state in either Palestine, "our ever-memorable historic home", or Argentina, "one of the most fertile countries in the world". Many of the socialist Zionist groups were more territorialist than Zionist, such as Nachman Syrkin's Zionist Socialist Workers Party (the Z.S.).
