The Anglo-Russian Convention, signed at St. Petersburg on 31 August 1907, contained provisions relating to Persia, Afghanistan, and Tibet. The text of the agreement would seem to suggest that the matters adjusted were purely local in character—an arrangement arrived at between two countries settling problems in far-away frontier regions. But the Anglo-Russian Convention was of much greater significance. It represented a change not only in Anglo-Russian relations, but in Britain's fundamental European policy. It also meant that the role of the Government of India, which had often been a powerful factor in the determination of foreign policy in the nineteenth century, became less significant. It seems highly probable, too, that in the years when Sir Edward Grey was Foreign Secretary (December 1905 to December 1916—holding office for a longer consecutive period than any other Foreign Secretary in the nineteenth or twentieth centuries, the next being Castlereagh, 1812–22) the permanent staff of the Foreign Office exercised more influence and had a more decisive voice in the conduct of the country's foreign policy than they ever had before of have had since.
