Peter III of Russia
Empress Elizabeth arranged for Peter to marry his second cousin, Sophia Augusta Frederica (later Catherine the Great), daughter of Christian August, Prince of Anhalt-Zerbst and Johanna Elisabeth of Holstein-Gottorp. The young princess formally converted to Russian Orthodoxy and took the name Ekaterina Alexeievna (i.e., Catherine). They married on 21 August 1745. The marriage was not a happy one but produced one son, the future Emperor Paul, and one daughter, Anna Petrovna (20 December 1757 – 19 March 1759). Catherine later claimed that Paul was not fathered by Peter: that, in fact, they had never consummated the marriage. During the sixteen years of their residence in Oranienbaum, Catherine took numerous lovers, while her husband did the same in the beginning.
History of England
In 1530, Catherine was banished from court and spent the rest of her life (until her death in 1536) alone in an isolated manor home, barred from contact with Mary. Secret correspondence continued thanks to her ladies-in-waiting. Their marriage was declared invalid, making Mary an illegitimate child. Henry married Anne Boleyn secretly in January 1533, just as his divorce from Catherine was finalised. They had a second, public wedding. Anne soon became pregnant and may have already been when they wed. But on 7 September 1533, she gave birth to a daughter, Elizabeth. The king was devastated at his failure to obtain a son after all the effort it had taken to remarry. Gradually, he came to develop a disliking of his new queen for her strange behaviour. In 1536, when Anne was pregnant again, Henry was badly injured in a jousting accident. Shaken by this, the queen gave birth prematurely to a stillborn boy. By now, the king was convinced that his marriage was hexed, and having already found a new queen, Jane Seymour, he put Anne in the Tower of London on charges of witchcraft. Afterwards, she was beheaded along with five men (her brother included) accused of adultery with her. The marriage was then declared invalid, so that Elizabeth, just like her half sister, became a bastard.
