Æthelstan was one of the first kings to write laws and enforce them. The first two laws were about paying money to the church, and making sure the poor were given money.

Æthelstan enforced the duty of charity on Æthelstan's local officials, specifying the amount to be given to the poor effectively establishing social welfare.
Æthelstan died on 27 October 939 (aged about 45)
