George I was King of Great Britain and Ireland from 1 August 1714 until his death, and ruler of the Duchy and Electorate of Brunswick-Lüneburg in the Holy Roman Empire from 1698. He was born in Hanover and was second-cousiin to Queen Anne, so it was only the banning of Catholics taking the throne which allowed him to become King.

During George's reign, more power was ceeded to Parliament and Sir Robert Walpole was probably the first de-facto Prime Minister. George was succeeded by his son, George II.
