[2] The alliance between Dukes Bolesław the Pious of Greater Poland and Barnim I of Pomerania was sealed with the marriage between Przemysł II, Bolesław's nephew, and Ludgarda, Barnim I's granddaughter.
[3] After a happy beginning, the relationship between the couple became more complicated due to Ludgarda's apparent infertility after almost ten years of marriage.
Ludgarda died suddenly in Gniezno, and was buried in the local cathedral on 14 December 1283, probably a few days after her death.
[4] According to Jan Długosz[5] and other contemporary sources, she was strangled by order of her husband, after her refusal of a divorce and return to Mecklenburg.
