Medieval Kraków, as a city located at the intersection of trade routes, quickly became one of the most important places for merchants. It was they who, traveling across Europe, connected Kraków with the continent through their transactions. Along with goods, they also carried political, religious, and cultural ideas. In my paper I will focus only on merchants from the Rhineland who settled in Kraków in the 15th century, such as Seweryn Bethman, the Schillings, and the Boners. I will attempt to trace their migration route to Kraków, reconstruct the international networks of contacts they established, both during their migration and after they were granted the privileges of Kraków’s municipal law, as well as take a closer look at the functioning of their trading companies. Additionally, I will try to identify the factors that contributed to their rapid rise, not only within the urban structures.
