 The most historic assumes that the marriage took place during the life of Jadwiga's father, and so no later than 1279.The second theory, which now has the most supporters, is that the wedding took place between 1290 and 1293, possibly at the conclusion of the meeting in Kalisz in January 1293, and that in 1279 there was perhaps only an engagement ("matrimonium de futuro").The third theory posits a specific date of the marriage as 23 April 1289.
