Jan Bażyński

[8] In service of the Grand Masters, Jan traveled on diplomatic missions to England, Denmark and Portugal in the years 1419–1422.

According to legend he was knighted by the King of Portugal for his military service against the Moors during the Reconquista, which was reflected in a modification to his family's coat of arms.

He was also a member of the Lizard Union, an organization of Prussian nobles and knights who sought the incorporation of Prussia into the Kingdom of Poland.

[9] He was a member of the Secret Committee of the Confederation[citation needed] and took a public stance against attacks made against the organization by the papal legate and the new Grand Master of the Order.

He was the head of the delegation which came from Toruń (Thorn) to Kraków in February 1454, which asked the King of Poland Casimir IV Jagiellon to reincorporate Prussian lands into the Polish kingdom.
