Another war with Russia followed in 1632 and was concluded without much change in the "status quo". King Władysław IV then proceeded to recover the lands lost to Sweden.

Courland, which had remained with the Commonwealth, assumed the servicing of Lithuania's Baltic trade. After Frederick William's last Prussian homage before the Polish king in 1641, the Commonwealth's position in regard to Prussia and its Hohenzollern rulers kept getting weaker.
