The 16th - 17th century Europe was a scene of religious wars and magnates rebellions against monarchy. In this time of «universal conspiracy» treason was treated as normal tool for political activity of elites. However, the analysis of sources (private and official correspondence, resolutions and constitutions of Diets etc.) leads us to conclusion that in the 16th century treason was regarded in Poland as something dishonorable, something suitable for plebeians and foreigners only.
