I have come across a reference on a number of websites which is very weird. This is it:
November 21, 1818 in History
Event: Russia’s Czar Alexander I petitions for a Jewish state in Palestine
The claim seems to be that the Russian Czar in some way wanted a Jewish state in Palestine, but I cannot actually find an actual reference to such an event. Though it’s quoted by many.
Zionism only came into existence decades later.
If anyone knows more, feel free to drop a comment.
