Signed on August 31 (August 18, O.S.) 1907 in St. Petersburg, the agreement between the Russian and British Empires marked the end of their long-standing geopolitical rivalry in Asia, known as the “Great Game.” The document became a major milestone in the formation of the early twentieth-century system of international alliances and laid the foundation of the Triple Entente — the coalition of Russia, Great Britain, and France aimed at containing German and Austro-Hungarian expansion.
The prerequisites for concluding the convention were the weakening of Russia’s international position after its defeat in the Russo-Japanese War and the revolutionary events of 1905, as well as Germany’s growing activity in the Middle East. For Britain, the agreement offered an opportunity to concentrate on European threats by removing the risk of confrontation with Russia along the Indian frontier.
The convention consisted of three sections — concerning Persia, Afghanistan, and Tibet. In the Persian question, both parties formally recognized the independence and territorial integrity of Persia but in practice divided the country into spheres of influence: the northern zone was assigned to Russia, the southern to Britain, and the central region was declared neutral. Russia pledged not to interfere in Afghan affairs, recognizing it as a British sphere of influence, while Britain promised to refrain from annexations and interference in the emirate’s internal politics. Regarding Tibet, both powers reaffirmed their recognition of Chinese suzerainty and agreed not to conduct direct negotiations with Tibetan authorities.
The signing of the agreement marked the end of open Anglo-Russian confrontation in Central Asia and created the conditions for diplomatic rapprochement between the two empires. Together with the Franco-Russian Alliance (1891–1893) and the Anglo-French Entente of 1904, it completed the formation of the Entente — a political and military bloc that played a decisive role in the balance of power on the eve of World War I.
At the same time, the convention had contradictory consequences. It was perceived in Persia and Tibet as an act of foreign arbitrariness that violated their sovereign rights. In Iran, the division of the country into “spheres of influence” provoked strong indignation among nationalists and parliamentarians and contributed to the escalation of political struggle during the Constitutional Revolution. Despite such criticism, the agreement strengthened Russia’s international position, allowing it to focus on European and Far Eastern affairs.
The Anglo-Russian Convention of 1907 thus became a key element of the diplomatic restructuring of the early twentieth century, marking the transition from a policy of isolation to a system of alliances that defined the configuration of world powers until 1914.
