Lodomeria

Lodomeria is a placename that was historically used to refer to parts of East-Central Europe, but with a meaning that shifted over time. The word is a Latinized form of the (dubious) Polish: Wladimeria, likely in turn from Old East Slavic, meaning "lands of Vladimir". This refers either directly to the ruler of Kievan Rus, Vladimir the Great (therefore meaning the lands conquered by him), or else refers to the city he founded and named for himself in CE 987, Wlodimer (or Volodymyr).

In the following centuries the name Lodomeria became synonymous with Galicia, broadly defined, or with Volhynia. After the Habsburg annexation of south-eastern borderlands of the Polish–Lithuanian Commonwealth, Lodomeria together with Galicia formed one of the many titles of the Emperor of Austria, "the ruler of Kingdom of Galicia and Lodomeria". However, Lodomeria existed only on paper, had no territory and could not be found on any map.

The American Notes and Queries published in 1889 stated that Lodomeria was an ancient district of Poland situated in eastern portion of the country. In 938 the Ruthenian Grand Prince Vladimir (Wladimir) annexed the principality and named it after himself. In 1198 the nominal title of a ruler of Lodomeria was created by one of his descendants. In 1340 King Casimir reunited Lodomeria with Poland.
