Mr. Herzl is the founder of modern Zionism - and therefore one of most important figures of the 20th century - although he is hardly known.
Herzl and many more other after him (including rich families like the Rothschields) tried for a long time to establish a Judenstaat for Jewish immigrants from all over the world. But none of the regional and colonial powers like the British and Ottoman Empire seriously supported the idea. The Zionist were not just religiously motivated, but reacted to a growing anti-Semitism in Europe (not just Germany, but also France and later in Russia).
Only after the Holocaust and a bloody struggle with their Arab neighbors and against international resistance was Israel established.
Theodor Herzl’s idea has come a long and bloody way.
