The Crimean War had ended in 1856 with Russia's defeat by an alliance of Britain, France, and the Ottoman Empire. The new and wary Alexander II of Russia waited some years so as not to antagonize the British, then Russia expanded into Central Asia in two campaigns. In 1864, a circular was sent to the consular officers abroad by Gorchakov, the Russian Chancellor, patiently explaining the reasons for expansion centering on the doctrines of necessity, power and spread of civilisation. Gorchakov went to great lengths to explain that Russia's intentions were meant not to antagonize the British but to bring civilised behavior and protect the traditional trade routes through the region. The first campaign started from Orenburg and proceeded in the direction of Kabul in Afghanistan. Russia occupied Chimkent in 1864, Tashkent in 1865, Khokhand and Bukhara in 1866, and Samarkand in 1868. Russia's influence now extended to outlying regions of Afghan Turkestan. The second campaign started from the Caspian Sea and was in the direction of Herat, near the Persian frontier. Khiva was occupied in 1873. Notable Russian generals included Konstantin Kaufman, Mikhail Skobelev, and Mikhail Chernyayev.
