Who is prince Edgar?

Prince Edgar was the only true heir to the English throne when Edward the Confessor died in 1066. He was most likely born in Hungary, and was the great-nephew of Edward. Though the only one related to Edward by blood, the throne was passed over to Harold Godwinson, who was Edward's brother-in-law. Edward had married Harold's sister Edith, and because they had no children, England was in a bit of a dilemma, trying to choose who the next heir should be. Because Edgar was born in Hungary, he had few supporters in England, the complete opposite of Harold, who was well-known as Harold, Earl of Essex.
