Edward was born in 962. Edward became king of England in 975.
In 975 King Edgar died. But Edgar did not disclose a heir to the Kingdom. That is why Edward and Ethelred, the children of Edgar, began to fight against each other to become king.
Edward knew that he had to take the support of the church to become king. That's why Edward made donations to the churches in large quantities. In addition, because of Edward's oldest childhood, the Church supported Edward as king. And in 975 Edward was declared king of England by the Church.
King Edward thought now that the throne struggle was over. And that's why he tried to strengthen Britain by stopping his brother's interest. In particular, Edward has been fair to the people of England.
But Ethelred continued to prepare for the fight against Edward. And in 978 he was killed by the supporters of Edward Ethelred. And the people of England addressed Edward as Edward the Martyr.
