engage, should an European force invade Persia, to assist either with troops, or a subsidy and the loan of officers. British officers were sent to Teherán to drill the Sháh's soldiery. A second treaty was provisionally signed at Teherán on March 14, 1812, and was definitely concluded between Great Britain and Persia on November 25, 1814. By this treaty the amount of the contemplated subsidy was fixed. The Persian Government further bound itself to use its influence with the States of Central Asia on behalf of Great Britain should any force, purposing to attack India, advance by that route. By Article VI it was stipulated that if Persia were at war with any European Power while at peace with Great Britain, the latter would endeavour to mediate. Mediation failing, and provided that Persia had not been in the first instance the aggressor, Great Britain would either send a force from India, or would pay during the war the prescribed amount of subsidy. Articles VIII and IX arranged that, if the Afghans were at war with the British, the Sháh would aid the latter with troops, at the cost of Great Britain, in numbers to be settled between the two Governments. If war broke out between Afgháns and Persians, the British Government would not interfere, unless its mediation should be applied for by both.
The fear of France passed with the fall of Napoleon. Now, apprehension of Russia arose. In 1813 a long period of unequal war between Russia and Persia had been brought to a close by the Treaty of Gulistán.
