I think Habsurg ruled the Austrian empire through much of the 19th century.
House Habsburg of Austria was regarded as the most influential/powerful house in Europe at that time. This house alone produce several emperors for different kingdom all across Europe, Including the Kingdom of Austria, , Kingdom of England ,Kingdom of Croatia, Kingdom of Germany, Kingdom of Hungary, and Kingdom of Spain that's what I know.
Hope it helps
