disestablishment of the Anglican Church
Specifically, the depriving the church of its right, privileges, or position as the Established Church of the United Kingdom.
As such it received the support, through taxation, of British subjects regardless of creed; and many, in order to exercise freedom of conscience, were forced to support it in addition to the Church of their convictions.
The system was manifestly unfair and movements to disestablish the Anglican Church resulted in the Irish Church Act, 1869, granting autonomous powers to the Irish Protestant Episcopal Church and making it dependent upon its adherents alone; and the Welsh Church Act, 1914, which, owing to the War required further legislation, 1920, to complete the disestablishment of the Anglican Church in Wales.
The movement in England itself has been strengthened by controversies resulting from the book, "," 1912, which displayed a trend towards doctrinal indifference; the Church of England Assembly (Power) Act, 1919, which secured greater freedom for the episcopacy.
