Morta

Morta (baptized c. 1252 by the bishop of Chełmno, died c. 1263) was the Grand Duchess of Lithuania (until 1253) and later Queen of Lithuania (1253–1262). There is very little known about her life; even her pre-Christianised name is unknown. The only clue into her origin or birthplace is a short mention in the comments following the treaty signed in 1219 between the Lithuanian dukes and Galicia–Volhynia. It says that Mindaugas killed many members of the Bulaičiai family, including Vismantas whose wife Mindaugas took for himself. It is generally assumed that Morta was Vismantas' wife. Edvardas Gudavičius, a modern Lithuanian historian, based on toponyms, determined that the Bulaičiai family most likely came from the Šiauliai region. Based on this evidence and hypotheses, residents of Šiauliai call the city home of Morta.
