The world of politics is ever-changing, no matter the country, spectrum, or political party.

And when it comes to the Prime Ministers of the United Kingdom, it's no different. The period between the 18th century and 20th century has been particularly interesting— and turbulent. That's why we have created the ultimate list of British Prime Ministers since 1770 (and previous serving individuals).

"The politician who never made a mistake never made a decision." — Prime Minister John Major (Conservative Party, 1990-1997)

Who Was the First Prime Minister of the UK?

Because Great Britain has undergone structural changes over the years, there are technically several "first" PMs. But historians agree that while the first person to ever hold the title was Sir Robert Walpole, the first Prime Minister of the current United Kingdom (including Northern Ireland) was Andrew Bonar Law in 1922.
