In 1066 the Normans (William the Conquerer) conquered England making up the dynasty of French origin.
In 1485 the Tudors took over after the battle of Bosworth. They were of Welsh origin. It is funny enough that in a time when illegitimate children were considered really the scum of the earth (the word "bastard" became an invective in those days) they were able to take the thrown based on the fact that one of Catherine of Valois' Welsh bodyguards guarded her body so closely that they ended up with six illigitimate children
In 1603 Elizabeth I., the last of the Tudors died leaving the throne to the Scotish Tudors.
In 1714 the throne went to the German family of the House of Hanover. Through the marriage of queen Victoria with Prince Albert of Saxe-Coburg-Gotha another German link was added to the family though in 1917 (due to WW1 sentiments) they took the more English name of Windsor.
As the question wasn't answered, here is the next one:
Which British warship was turned into a museum ship which nowadays is anchored near the Tower Bridge in London (special laurel for those who can also name the battle ship which this British ship helped to sink).
