ah, so you rely on wikipedia! That's MUCH better! LOL.
I'll help you out because you seem to be floundering:
You seem to want to discuss "modern political Zionism" as if it is the only "Zionism" that exists. It isn't.
Here is a quote that might help you understand
"While there has been a continuous Jewish presence in the land of Israel over the millennia, the yearning to return to Zion, the biblical term for both the land of Israel and Jerusalem, has been a cornerstone of Jewish communal life since the Romans violently colonized the land, sending Jews into exile two thousand years ago. An earlier exile by the Babylonians produced perhaps the most well-known lamentation “By the rivers of Babylon, there we wept as we remembered Zion.” That connection between Jews and the land, and the hope for repatriation, is deeply embedded in Jewish prayer, ritual, literature and culture."
You seem to like wikipedia so how about
this page which presents a timeline of Zionism starting in the 16th century. That's not the origin, but it shows that a wikipedia page records the concept of Zionism from well before the 19th century. Let me know if you need me to do any more real, adult-level thinking for you.
