2551: When was the 1st British Prime Minister Dec 7, 2021

What is now thought of with the title of 'prime minister' was only called First Lord of the Treasury, officially, before 1905 in Great Britain. This was used for Prime Minister Sir Henry Campbell-Bannerman, who was also First Lord of the Treasury. This is still true today with prime ministers also carrying the less well known title of First Lord of the Treasury. The man usually credited as being the first Prime Minister, Robert Walpole was only de facto the first, but in 1721 was technically named First Lord of the Treasury.
