sentences:  Older sources claim that Chełm Land became part of Ruthenian Voivodeship at the time of its creation in 1434, but according to new research, it remained an independent unit of administration, with its own sejmik, until probably early 16th century.At first Chełm Land consisted of Chełm County and Krasnystaw County, but in 1392 it was expanded by the area of Hrubieszow, which had previously belonged to Belz Land.Furthermore, in the 1430s, Chełm Land was expanded by vast areas east of the Bug river, the Counties of Ratno and Luboml.
