The newly united Britain fought France in the War of the Spanish Succession from 1702 to 1713, and the War of the Austrian Succession from 1740 to 1748, attempting to maintain the balance of power in Europe. The British had a massive navy but maintained a small land army, so Britain always acted on the continent in alliance with other states such as Prussia and Austria as they were unable to fight France alone. Equally France, lacking a superior navy, was unable to launch a successful invasion of Britain.
