Judeopolonia, also Judeo-Polonia, is an antisemitic conspiracy theory positing future Jewish domination of Poland.

[1][2][3] The idea had its roots in an 1858 book by Julian Ursyn Niemcewicz, but did not gain currency in anti-semitic tracts until around 1900.

[1] In 1912, author Teodor Jeske-Choiński had Jews in his book rhetorically say: "If you do not allow us to establish a 'Judeo-Polonia state' and a nation of 'Judeo-Polish people,' we will strangle you.

[2] Zoltán Halasi [hu] writes that Szcześniak presents Jews as informers for the tsar, "tightfisted hyenas" and arrogant oppressors of the Polish people.

[4] Szczęśniak gives the name of Judeopolonia to the League of East European States, a suggested German client state with autonomous Jewish cooperation, proposed for the territory between Germany and Russia by the German Committee for Freeing of Russian Jews in 1914.
