The Hapsburg (or Habsburg) and the successor family, Habsburg-Lorraine, were important ruling houses of Europe and are best known as the ruling Houses of Austria (and the Austrian Empire) for over six centuries. They also at times controlled Germany, Spain, and Mexico.
The Spanish King Philip II was the first Hapsburg King of Spain. Under his leadership, Spain considerably expanded the Hapsburg empire.
In 1588, Philip's daughter Isabella was installed as Queen of England. She married Albert, her cousin and an Austrian Hapsburg, who became England's King.
After Philip II died, Isabella and Albert were overthorwn by a popular uprising led by Robert Cecil and barely manged to flee England in a boat sailing down the Thames in the night. Spain continued to be ruled by the Hapsburgs in the person of Philip III.
