>>101778079The last Hapsburg king of Spain.
Because he died childless that meant the king of France would inherit the throne of Spain, uniting the two into one giga-country that could beat up pretty much anyone else.
The rest of Europe NOPE'd the fuck out and declared war.
The deaths of hundreds of thousands (and the beginning of the end of Spain as a major power) ensued before everyone eventually agreed that a Bourbon could inherit the throne of Spain as long as it wasn't the king of France.
All because generations of Spanish kings couldn't resist dat niece pussy.
