Oldest son of Philip V of Spain and his first wife Maria Luisa of Savoy, he became King in January, 1724 following his father's abdication, but died 8 months later from smallpox, placing his father back on the throne.
However, what if he does not die from small pox say he never catches the disease, what consequences might this have?
He was married to Louise Elisabeth D'Orleans daughter of the regent of France, so there are obvious ties to France there, would he get involved in things such as the War of Polish Succession as his father did? Would he look to regain lost Spanish possessions?
How might he improve the Spanish economy?
Furthermore, his step-mother was said to be a rather scheming woman, would there be issues there?
