The study is devoted to the courts of the sovereigns from the dynasty of the House of Jagiellon with an emphasis on the turn of the 16th century when the Jagiellonian dynastic space was shaped by immediately several court centres. The late medieval Jagiellonian monarchs were analysed as mutually connected power centres of a single dynastic space. The emphasis was places on the mobility of the courtiers between the Jagiellonian centres and also on the dynastic strategies of the upper and lower nobilities from the individual lands ruled by the Jagiellonians, when the representatives of a single family entered the services of various, at the given time contemporaneously appearing members of the ruling dynasty. The conducted analytical probes indicated the beginning of a process, which under certain circumstances could have led to the emergence of a collective elite of a wider, dynasty-wide defined space.
