Queen Christina (1626-1689) ruled Sweden in her own right as queen regnant (as opposed to queen consort) betwen 1632 and 1654.

She is often described as having had an intimate relationship with her lady-in-waiting, Ebba Sparre, although it is not clear whether they were lovers.

In 1654 she abdicated in order to convert to Catholicism, and spent the latter years of her life in France and Italy. She is buried in St. Peter's Basilica in Rome.
