How many Tudor kings and queens were there?

There were three Tudor kings crowned and two Tudor queens. King Henry VII was the first Tudor king, followed by his son, King Henry VIII, followed by his only son (by Jane Seymore) King Edward VI, followed Henry's eldest daughter (by Katherine of Aragon), Queen Mary I (also known as "Bloody Mary"), and finally Henry's second daughter (by Anne Boleyn) Queen Elizabeth I. The Tudor dynasty died with Queen Elizabeth who never married and thus produced no heir.
