OrenburgOrenburg (Оренбу́рг, ɐrjɪnˈburk; Орынбор), formerly known as Chkalov (1938–1957), is the administrative center of Orenburg Oblast, Russia. It lies on the banks of the Ural River and is southeast of Moscow. Orenburg is also very close to the border with Kazakhstan. Several historians have tried to explain the origins of the city's name. It was traditionally accepted that the word "orenburg" means a fortress on the River Or. In all probability, the word combination "orenburg" was proposed by ru, the founder of the city.

CossacksThe Cossacks are a predominantly East Slavic Orthodox Christian people originating in the Pontic–Caspian steppe of Ukraine and southern Russia. Historically, they were a semi-nomadic and semi-militarized people, who, while under the nominal suzerainty of various Eastern European states at the time, were allowed a great degree of self-governance in exchange for military service. Although numerous linguistic and religious groups came together to form the Cossacks, most of them coalesced and became East Slavic-speaking Orthodox Christians.
