<P> Prior to the creation of the UK , Wales had been conquered and annexed by the Kingdom of England . This meant that the United Kingdom created in 1707 by the Treaty of Union between England and Scotland encompassed all of Great Britain . The Kingdom of Ireland merged with this state in 1801 to form the United Kingdom of Great Britain and Ireland . Five - sixths of Ireland seceded from the UK in 1922 , leaving the present formulation of the United Kingdom of Great Britain and Northern Ireland . There are fourteen British Overseas Territories , the remnants of the British Empire which , at its height in the 1920s , encompassed almost a quarter of the world 's land mass and was the largest empire in history . British influence can be observed in the language , culture and legal systems of many of its former colonies . </P>
