The earliest postmasters had responsibility for England and Wales. In 1707, on the Union with Scotland, the responsibility of the office was extended to cover the whole of the new Kingdom of Great Britain as well as Ireland, but with some powers held by a Post Office Manager for Scotland. By the Post Office (Revenues) Act 1710, with effect from 1711, the services were united, but with a Deputy Postmaster for Scotland. From 1784, there were also Postmasters General of Ireland, but from 1831, the postmasters based at Westminster became responsible for the whole of the United Kingdom of Great Britain and Ireland. In 1922, the Irish Free State became independent, and in 1923 it established its own arrangements under a Postmaster General of the Irish Free State. In 1924 the title became Minister for Posts and Telegraphs. From 1691 to 1823 there were two Postmasters General, to divide the patronage between the Whigs and Tories. In 1823 the idea of a Whig and a Tory sharing the post was abolished.
