Piotr Skarga of the Powęż coat of arms was born in 1536. He studied philosophy at the Krakow Academy in the years 1552-1555, in 1564 in Lviv he was ordained a priest, and in 1569 in Rome he joined the Jesuit order. King Sigismund III Vasa bestowed upon him the Powęża coat of arms of the Skarga-Powęski.

After the death of Louis of Hungary in 1382, king of Hungary and king of Poland, in 1384 his daughter Jadwiga Andegawenska, great-granddaughter of Polish king Ladislaus I the Short, inherited the Polish throne.

She had to choose a husband, who became Ladislaus Jagiello, Grand Duke of Lithuania. According to modern laws, it was a paedophile relationship, because Jadwiga at the first meeting with Jogaila was 13 years old at the most, and she was more than 20 years younger than Jogaila. However, this age difference did not prevent them from having a consensual relationship later on. It was also a well-matched political marriage, in which Lithuania and Poland were united by a personal union, later called the Republic.
