Pro populo anglicano defensio, translated as 'Defense of the English People,' is a significant political pamphlet written by John Milton in 1651. It argues for the defense of the English people against tyranny and oppression, particularly during the tumultuous times of the English Civil War and the Commonwealth period. This work reflects Milton's deep commitment to republican ideals and his belief in the right of the people to resist unjust authority, making it a cornerstone of his political thought and a vital part of his major works.
