The Kharkiv Sloboda Cossack Regiment (Ukrainian: Харківський слобідський козацький полк) was one of five territorial-administrative subdivisions of the Sloboda Ukraine. The regiment's capital was the city of Kharkiv, now in Kharkiv Oblast of Eastern Ukraine.
The Kharkiv Regiment appeared between 1651 and 1659 years. In 1732 it consisted of 19 sotnias. In 1765, the sloboda regiments was abolished, and its territory was reformed into the Sloboda Ukraine Governorate.
The settlement of future regimental lands by settlers from the territory of the Polish–Lithuanian Commonwealth took place against the backdrop of uninterrupted military operations in the Dnieper and Western Ukraine, burdened by punitive expeditions of the Polish–Lithuanian Commonwealth, as well as by fratricidal civil war involving foreign troops (Tatars and Turks).
The first wave of immigrants from the Right Bank Ukraine to the territory of the Moscow kingdom to the border with Wild Field followed the defeat of the troops of Bogdan Khmelnytsky in the Battle of Berestechko in 1651. The western part of the Polish-Moscow treaty was reaffirmed by the Polish–Lithuanian Commonwealth. Hetman Bohdan Khmelnytsky publishes a versatile person that allowed the population to relocate to the land of the Moscow kingdom.
After the death of hetman Bohdan Khmelnitsky, authority passed into the hands of hetman Ivan Vyhovsky. A period of civil war (1657-1658) began between supporters of the Moscow and Polish courses, the so-called "The Ruin". The population once again began to move to calmer areas under the authority of the Moscow tsars.
At the head of the regiment were elected colonels and regimental starshina (officers). They were chosen not for a limited time, but for life. However, they could be deprived of the position by the Russian tsar (later the emperor), or by a decision of the assembly of the elders.
The colonel of the Slobodsky Cossack regiment represented both administrative and military power. The colonel had the right to issue decrees, with his signature - universal. The symbol of the colonel's power was a pernach, a regimental crown, a colonel seal.
The regimental starshina (headquarters) consisted of six people: an obozni (quartermaster), a judge, an osavul, a khorunzhy, a two chancellors.
The regiment was divided into sotnias.
Sotnia is an administrative unit within the regiment. A Sotnia was headed by a sotnik. He was endowed with extensive military, administrative, judicial and financial powers. Originally elected by the Cossacks of the sotnia, later he was chosen by a sotnia starshina and was confirmed by the colonels from among the elders.
The Sotnia starshina (headquarters) consisted of a sotnik, a Sotnia otaman, an osavul, a chancellor and a khorunzhy. The positions of the duties coincided with the regimental ones:
