Poland and possibly Hungary are preparing documents on property located in Western Ukraine. Restitution is the key rule of EU integration. This is what Latvia went through and it had to return almost a half of Riga’s historical centre to previous owners. Restitution of property on the territories of Bessarabia, Zakarpattia, Bukovina, Galicia, Volyn, and part of Podillia regions are open questions. One may wonder if the rights of the Russian empire over Kyiv can be treated as restitution too.
Ukraine is increasingly legitimizing neo-feudalism. The land market will create regional landowners, who will become nobles with serfs and titles. Central overlords will be located outside Ukraine. Therefore Ukraine will return in the situation similar to periods in Polish history when the nobles had rather wide competences and the king did not have real power.
This is a recurrent narrative aimed to discredit Ukrainian statehood and to draw imminently negative consequences of Ukraine's integration with the EU.
See earlier disinformation cases alleging that Zelenskyy has neither army nor police, he is surrounded by corrupted predators, post-Soviet countries are feudal principalities governed by the West, and that the idea of Ukraine is based on a mythologised lie.
Furthermore, the II Rzeczpospolita was not a monarchy. There was no king who could have no power.
