Charles II of Spain is, as many of you are aware, the poster child for Habsburg inbreeding. His infertility led to the devastating War of the Spanish Succession, in which France and Austria and their allies jockeyed for the division of the Spanish empire amongst themselves.
But what if he had heirs?
No, these heirs would not be his hypothetical children; it would be nigh-impossible for him to have children with his genetic defects. There is another way, though.
John Joseph of Austria was the illegitimate son of Philip IV of Spain with an actress. Notably he was Philip IV's only legitimized illegitimate child; the king made him a prince with the title of His Serene Highness and set him to work as an administrator and representative of the king. He was a major player in court politics and in 1679 secured the position of prime minister to his half-brother Charles II, but died suddenly- some suspect poison.
But what if John Joseph of Austria had had issue? IIRC his father wanted him to marry one of the Mazarinettes, the seven nieces of France's powerful Cardinal Mazarin, but he deferred. Are there any other alternate bride options for John Joseph?
Also. In the event that John Joseph and his wife have children (and for scenario's sake, say he dies as OTL in 1679 poisoned), would these children be accepted by the powers of Europe as heirs to Spain? IIRC, the Nine Years War halted because everyone wanted to wait until Charles II's death. If Charles II has nephews lined up to succeed him, would the 9 Years' War keep dragging on? How would this affect European politics in the last years of the 17th century, and going forward? Would Louis XIV use the unpaid dowry thing to press his claim to the Spanish Netherlands?
