The list of witnesses on the charter of Henryk IV Probus from 1283 contains the name of a 'Petrus de Cracouia palatinus Wratizlauiensis'. Besides this one appearance no other Silesian sources mention any Wroclaw palatine of that name. The only clue that allows to identify him is the phrase 'de Cracouia'. The author of the article rejects the possibility that Piotr may have come from a place with a similar name, possibly in Bohemia or Germany. He argues that Piotr the palatine of Wroclaw is identical with the voievode of Cracow, Piotr Wojciechowic (1280), often identified with Piotr Bogoria, the father of the archbishop of Gniezno, Jaroslaw Bogoria of Skotniki. The reason why Piotr disappeared from Little Poland and appeared at the court of Henryk Probus was, according to the author, the rebellion against Leszek the Black in 1282, so often questioned in the literature. The appearance of Piotr in the environment of Henryk Probus is an interesting example showing how the duke of Wroclaw interfered in the internal matters of Little Poland.
