Koba, the alias youth. Underneath Dzhugashvili was known in the revolutionary ranks in the Caucasus. Consensus, where did that nickname, no. There are several assumptions.
Variant literary
One version says that the Patriotic hero of the novel by Alexander Kazbegi "Patricide" was distinguished by its persistence and the desire to go to the target of any casualties. These and other qualities of character of Koba - a literary character - a young Stalin very impressed, and the style of behavior and dedication Dzhugashvili, like a mask, try on, so for a long time, the future "father of Nations" were asked to name themselves that way - Koba.
Years later, having gained power and got rid of the closest allies, which could make him vulnerable, Stalin, historians on the basis of eyewitness accounts, is literally changing the face when his name was called Koba.
Option Royal
Not less plausible version of the origin of the nickname from the Georgian version of the name of the Persian king of Abadesa.
Medieval Georgia the period of his reign had important historical value. When it is the country's capital was Tbilisi, and the country suffered a serious economic momentum established trade relations, developed new crafts appeared first irrigation device gardens.
Historians have noted similar points in the biographies and traits of the Tsar and Stalin. Strong-willed, strong character, uncompromising manner of the reign of Abadesa respected Dzhugashvili, it is difficult to say whether the copied young revolutionary historical character, but the fact that Stalin was well acquainted with the history of the reign of Abadesa obvious.
Trotsky in the memoirs wrote that there was a period when Dzhugashvili was called by the double name of Koba-Stalin, and behind it and is called - "KINTO", which translated means "nimble rogue and a cynic". Was the name of Stalin and Besoshvili, and Companion To, but they disliked the nickname Soso got from my mother, who called him affectionately Sotelo.
