With Britain's old rivals no-longer a threat, the nineteenth century saw the emergence of a new rival, the Russian Empire, and a strategic competition in what became known as The Great Game for supremacy in Central Asia. Britain feared that Russian expansionism in the region would eventually threaten the Empire in India. In response, Britain undertook a number of pre-emptive actions against perceived Russian ambitions, including the First Anglo-Afghan War (1839–1842), the Second Anglo-Afghan War (1878–1880) and the British expedition to Tibet (1903–1904). During this period, Britain also sought to maintain the balance of power in Europe, particularly against Russian expansionism, who at the expense of the waning Ottoman Empire had ambitions to "carve up the European part of Turkey". This ultimately led to British involvement in the Crimean War (1854–1856) against the Russian Empire.
