Sloboda Ukraine in the context of "Zaporozhian Cossacks"

Kharkiv is the second-largest city in Ukraine. Located in the northeast of the country, it is the largest city of the historic region of Sloboda Ukraine. Kharkiv is the administrative center of Kharkiv Oblast and Kharkiv Raion. Prior to the Russian invasion of Ukraine in early 2022, it had an estimated population of 1,421,125.

Founded in 1654 as a Cossack fortress, by late 19th century Kharkiv had developed within the Russian Empire as a major commercial and industrial center. From December 1919 to January 1934, Kharkiv was the capital of the Ukrainian Soviet Socialist Republic. During this period migration from the distressed countryside and a relaxation of restrictions on Ukrainian cultural expression changed the city's ethnic complexion: Ukrainian replaced Russian as the largest recorded nationality. It was the sixth largest city in the Soviet Union during its existence.

Sumy Oblast (Ukrainian: Сумська область, romanized: Sumska oblast), also known as Sumshchyna (Сумщина), is an oblast (province) in northeast Ukraine. The oblast was created in its modern-day form, from the merging of raions from Kharkiv Oblast, Chernihiv Oblast, and Poltava Oblast in 1939 by the Presidium of the Supreme Soviet of the Soviet Union. The estimated population is 1,035,772 (2022 estimate).

The administrative center of the oblast is the city of Sumy. Other important cities within the oblast include Konotop, Okhtyrka, Romny, and Shostka. The modern region combines territories of the historical Severia (northern part) and Sloboda Ukraine (southern part). On territory of the Sumy Oblast important centers of Ukrainian culture are located, such as the city of Hlukhiv which served as a hetman residence during the Cossack Hetmanate as well as the cities of Okhtyrka and Sumy which were regional centers of the Sloboda Ukraine.

Kharkov Governorate was an administrative-territorial unit (guberniya) of the Russian Empire founded in 1835. It embraced the historical region of Sloboda Ukraine. From 1765 to 1780 and from 1796 to 1835 the governorate was called Sloboda Ukraine Governorate. In 1780–1796 there existed the Kharkov Vicegerency (Ukrainian: намісництво, romanized: namisnytstvo; Russian: намесничество, romanized: namestnichestvo).

From 1765 to 1780, the Sloboda Ukraine Governorate existed. In 1780, the Kharkov Viceroyalty was established and lasted until 1796. In 1835, the Viceroyalty was again reorganized into the Sloboda-Ukrainian Governorate, and from 1835 onwards, the Kharkov Governorate was formed, which existed until 1925. With each reorganization, the boundaries and administrative structure change significantly. The main state tax implementation, processing, and publishing of statistical information for the Kharkov governorate was the Kharkov Governorate Statistical Committee.

Kharkiv, also known as Kharkov, is the second-largest city in Ukraine. Located in the northeast of the country, it is the largest city of the historic region of Sloboda Ukraine. Kharkiv is the administrative center of Kharkiv Oblast and Kharkiv Raion. Prior to the Russian invasion of Ukraine in early 2022, it had an estimated population of 1,421,125.

From December 1919 to January 1934, Kharkiv was the capital of the Ukrainian Soviet Socialist Republic.

The Zaporozhian Cossacks or Zaporizhian Cossacks, also known as the Zaporozhian Cossack Army or the Zaporozhian Host (Ukrainian: Військо Запорозьке, romanized: Viisko Zaporozke), were Cossacks who lived beyond (that is, downstream from) the Dnieper Rapids. They were predominantly Ruthenians, but also included other ethnic groups (most notably their legendary Kosh Otaman Ivan Sirko was of Moldavian origin). Scientific studies conducted on the Zaporozhian Cossack genetics show that their Y-chromosomal genetic makeup forms the southern fragment of East Slavic population, with minimal levels to absence of Caucasian and Asian component in their paternal gene pool. Along with Registered Cossacks and Sloboda Cossacks, Zaporozhian Cossacks played an important role in the history of Ukraine and the ethnogenesis of Ukrainians.

The Zaporozhian Sich grew rapidly in the 15th century from serfs fleeing the more controlled parts of the Polish–Lithuanian Commonwealth. The least controlled region, that was located between the Dniester and mid-Volga was first known from the 15th century as the Wild Fields, which was subject to colonization by the Zaporozhian Cossacks. Zaporozhian Host became established as a well-respected political entity with a parliamentary system of government. During the course of the 16th, 17th and well into the 18th century, the Zaporozhian Cossacks were a strong political and military force that challenged the authority of the Polish–Lithuanian Commonwealth, the Tsardom of Russia, and the Crimean Khanate.

Sumy (Ukrainian: Суми, IPA: [ˈsumɪ] , Russian: Сумы) is a city in northeastern Ukraine. It serves as the administrative center of Sumy Oblast. The city is situated on the banks of the Psel River and has a population of 256,474 (2022 estimate), making it the 23rd-largest in the country.

The city of Sumy was founded in the 1650s by Cossacks within the historical region of Sloboda Ukraine.

Okhtyrka (Ukrainian: Охтирка, IPA: [oxˈtɪrkɐ] ; Russian: Ахтырка, romanized: Akhtyrka) is a city in Sumy Oblast, Ukraine. It serves as the administrative center of Okhtyrka Raion within the oblast.

Okhtyrka was once home to Hussars and Cossacks. It was also in the past a regional seat of the Sloboda Ukraine Imperial Region and of the Ukrainian SSR. Since the discovery of oil and gas in 1961, Okhtyrka has come to be known as the "oil capital" of Ukraine. It is home to the former Okhtyrka air base and other historical and religious sites. Some religious buildings in Okhtyrka were almost destroyed in the Russian invasion of Ukraine.
