 Charles III, as he was known, disembarked in his kingdom in 1705, and stayed there for six years, only being able to exercise his rule in Catalonia, until the death of his brother, Joseph I, Holy Roman Emperor; he returned to Vienna to assume the imperial crown.Not wanting to see Austria and Spain in personal union again, the new Kingdom of Great Britain withdrew its support from the Austrian coalition, and the war culminated with the Treaties of Utrecht and Rastatt three years later.The former, ratified in 1713, recognised Philip as King of Spain; however, the Kingdom of Naples, the Duchy of Milan, the Austrian Netherlands and the Kingdom of Sardinia – all previously possessions of the Spanish—were ceded to Austria.
