I am looking at a particular moment in Polish history when Louis I of Hungary died in 1382. Although the Hungarian throne was inherited by his daughter Mary, local power brokers back in Poland did not want Mary and negotiated for her younger sister Jadwiga to be monarch instead. Jadwiga finally came to Kraków and at the age of ten, on 16 October 1384 (or possibly 1385), was crowned 'King' (not Queen for legal reasons) of Poland.
My question is - why did they find Jedwiga more acceptable than Mary? One reason I have seen is they did not want to 'continue the personal union with Hungary' but that doesnt make sense to me since they both have the same father and are therefore involved in that Hungarian union.
