Charles XII had spent more than twenty years on the throne without marrying or producing an heir. One interpretation treats that choice partly as a court-management problem: a dynastic marriage could strengthen one faction while the campaigning king was absent. Charles's faith and unmarried life have encouraged later speculation about his sexuality, but affectionate male correspondence and dynastic marriage practices must be read in the language and expectations of the period. His sister Ulrika Eleonora secured recognition from the Riksdag of the Estates by surrendering the powers of absolute monarchy. She then handed the throne to her husband Frederick, whose political weakness left committees and factions struggling to agree on resources and policy.
