end of the Caucasus War marked the end of the Line Cossack Host. In 1860 it was divided, with the two western regiments joining the Black Sea Cossacks to form the Kuban Cossack Host and the remaining into the Terek Cossack Host. The next decade showed a gradual reform from military to civil control. In 1865 a permanent police force was formed, and in 1869 the Terek Oblast was formed, consisting of eight mountainous districts (populated by indigenous people) and seven Cossack subdivisions. Several regimental reforms followed: Kizlyar and Rower as well as Mountain and Mozdok regiments were united into two (reducing the number of sub-divisions to five), and in 1871 a charter for Terek Cossacks was published. From the 1870s onwards the Eastern Caucasus remained largely peaceful (if one discounts uprisings waged by the Chechens in the late 1870s and the occasional exchange of raids). However the Terek Cossacks took part in several Imperial Wars, including campaigns against Khiva in 1873. During the Russo-Turkish War (1877–1878) the Terek Cossacks sent six cavalry regiments, one Guards squadron and one mounted artillery regiment to the Balkans and a further seven regiments and mounted battery were mobilized against the rebelling Chechens and Dagestanis, who initiated an uprising against Tsarist authorities in 1878. In the 1880s the arrival of the railways and the discovery of oil made the Terek Oblast one of the wealthiest in the Caucasus, resulting in a large growth in Cossack and indigenous mountain populations. This created friction on land ownership. The Cossacks held extensive fertile areas in the lowlands and steppes, whilst the indigenous mountain populations only held land in the mountainous zones. Peace was preserved, by a complex Russian policy of supporting loyal clan leaders and free supplies of food and goods The Terek Cossacks took part in campaigns against Geok-Tepe in 1879 and in 1885 up to the Afghan border in Central Asia. Uniform and equipment Until 1914 the Terek Cossack Host wore a full dress uniform comprising a dark grey/black kaftan (knee length collarless coat) with light blue shoulder straps and braid on the wide cuffs. Ornamental containers (czerkeska) which had originally contained single loading measures of gunpowder for muzzle-loading muskets, were worn on the breasts of the kaftans. The kaftan had an open front, showing a light blue waistcoat. Wide grey trousers were worn, tucked into soft leather boots without heels. Officers wore silver epaulettes,
