The palatine is the duke's first officer: he leads the host, judges in the duke's place and speaks for the Masovian lords at court.
Under a boy duke and an absent regent he is the strongest man in Masovia. The office is attested before and after 1200 (Żyron in the 1170s-1180s; Krystyn in the 1210s, killed in 1217), but no palatine is named for the winter of 1199-1200.
