Michałów Land or Michelauer Land (Polish: Ziemia michałowska, German: Michelauer Land, Latin: Terra Michaloviensis) is a historical region in central Poland, now part of the Kuyavian-Pomeranian Voivodship. During the Middle Ages, it was a disputed territory between the Kingdom of Poland and the Teutonic Knights.
It was named after Castle Michelau/Michałowo (it is part of the city of Brodnica (Strasburg), which was destroyed well before 1789).
From a geographical perspective, it was sometimes also considered part of Kulmerland, although it is east of the river Drwęca (Drewenz). The land of Michałowo and Lubawa (Löbau) were part of Prussian territory in direct vicinity of the Kulmerland.
Conquered in the 11th century a territory named Masovia developed as borderland between the Prussians and Masovians, who at a time of the fragmentation of Poland had made themselves independent of the Polish rulers. The small territories of Michelau and Löbau were bouncing back and force in between.
The rulers of Kujavia and Masovia had given lands to the monk and apostle of the Prussians, Christian of Oliva, He was declared first bishop of Prussia by the pope and he also bought additional territories. A Prussian chieftain had given bishop Christian his land Löbau, by accepting Christianisation at Rome.
