On 1 August 1714, George I ascended the throne of Great Britain following the death of Queen Anne. His accession was secured under the terms of the Act of Settlement 1701, which ensured that the British crown would pass only to Protestant heirs, thereby bypassing numerous Catholic claimants who held closer blood ties to the Stuart line. As the Elector of Hanover, George became the first monarch of the Hanoverian dynasty, marking a significant transition in the royal lineage of the nation.

The arrival of the new king brought about profound shifts in the governance of the country. Because George I was primarily focused on his German territories and faced a language barrier in his new realm, he relied heavily on his ministers to manage domestic affairs. This practical necessity accelerated the development of the cabinet system and altered the traditional balance of power between the monarchy, the government, and Parliament. Over time, this period laid the foundations for the constitutional monarchy that would define the subsequent centuries of British political life.

The transition of power was characterised by several key factors that shaped the early Georgian era:

• The strict enforcement of the Protestant succession to maintain political stability.
• The establishment of the Hanoverian line, which would rule Britain for over a century.
• A gradual reduction in the direct personal influence of the sovereign over day-to-day administration.
• The increased authority of parliamentary ministers in steering national policy.
• The formal union of the British crown with the interests of the Electorate of Hanover.
