Vem gifte sig med Jacob Kettler?

Jacob Kettler (German: Jakob von Kettler; Latvian: Hercogs Jēkabs Ketlers; 28 October 1610 – 1 January 1682) was Duke of Courland and Semigallia from 1642 to 1682. Under his rule, Courland and Semigallia became more independent of its Polish suzerain, reached its peak in wealth, and even engaged in its own overseas colonization, making it one of the smallest, but fastest growing states in the world at that time.

Yet, in the end the results of his rule failed in the confrontation with much stronger powers both directly in the Baltic (Sweden) and overseas (Dutch Republic). A ruler "too rich and powerful to be a duke but too small and poor to be a king" could not, with his small ancestral territory and very limited resources, play the powerful role he sought in European politics of that time.

Louise Charlotte av Brandenburg, född 13 september 1617 i Berlin, död 29 augusti 1676 i Mitau, var en hertiginna av Kurland 1645-1676. Hon föddes prinsessa av Brandenburg och var den äldsta dottern till kurfurst Georg Vilhelm av Brandenburg och Elisabeth Charlotta av Pfalz.

Louise Charlotte gifte sig 6 oktober 1645 med hertig Jakob av Kurland. Simon Dach tillägnade ett poem till deras vigsel.

Louise Charlotte var politiskt aktiv; hon utövade en probrandenburgsk politik men anses också ha bidragit till att Kurland upplevde en blomstring under makens regeringstid. Förhandlingar mellan Brandenburg, Ryssland, Sverige och Polen tog plats i Mitau under hennes de facto regeringstid.
