Rzeczpospolita i państwa Europy Wschodniej wobec wojny trzydziestoletniej (do 1635 r.) - rekonesans

The article discusses the Thirty Years' War from its outbreak until the end of the Swedish period in 1635. It attempts to present Poland's, Sweden's and Russia's attitudes towards the biggest armed conflict in 17th century Europe. It also analyzes the war in Prussia (1626-1629) with the aim of establishing whether it constituted the second front of the Thirty Years' War. The author is aware that this discussion is still far from reaching conclusions.
