The King James Bible translation came about because the Puritans called for a new translation during the 2nd day of the Hampton Court Conference on 16 Jan 1604.
This conference was called by James 1 in response to a petition from the Puritans to James I for reforms within the Church of England. [p. 15: A Visual History of the King James Bible by Donald L. Brake, HC 2011 ed].
The Puritans favour the Geneva Bible [1560], while the Anglicans support the Bishops’ Bible [1568].
James I hated the Geneva Bible. He agreed to a new English translation on the condition that it must spread the idea of divine rule by monarchs. The new translation became the King James Bible of 1611.
The Church in Rome was against any vernacular translation of the Latin Bible.
The first English translation of the Bible was by John Wycliffe in 1382, called the Wycliffe Bible.
