On 8 March 1702, Queen Anne ascended the throne following the death of William III. As the last monarch of the House of Stuart, her accession marked a significant transition in British history, occurring during a period of intense political and military upheaval. Her reign was defined by the complexities of European conflict, the rise of fierce party politics between the Whigs and the Tories, and profound constitutional shifts that would reshape the nation.

The most enduring legacy of Anne's time as sovereign was the formal unification of the kingdoms of England and Scotland. Through the Acts of Union 1707, the two countries were joined to create the single sovereign state of Great Britain, establishing a unified parliament and a shared national identity. This period of consolidation was central to the development of the British state during the early eighteenth century.

Key developments during the reign of Queen Anne included:

• The succession of the final Stuart monarch.
• The formal union of England and Scotland in 1707.
• The creation of the Kingdom of Great Britain.
• The escalation of major military conflicts across Europe.
• The growth of influential and partisan political factions.

Throughout her rule, Anne navigated a volatile political landscape characterised by the struggle for influence between competing interests. Her reign remains a pivotal chapter in the Stuart Britain era, bridging the gap between the seventeenth-century struggles for power and the emergence of a more stable, unified parliamentary system in the years that followed.
