Правобережная Украина
In 1653 on the banks of Vorskla tributary Akhtyrka a group of migrants from the right-bank Ukraine established a settlement which adopted the name of the nearby outpost. In 1654 there was completed a construction of fortification which in 1655-1656 further expanded by Russian "sluzhilie" (service members) led by the Tsar's appointed voivodes Larion Kaminin and Trofim Chernov. In 1656 there arrived the biggest group of people from the Right-bank Ukraine (over 1,000) led by Cossack sotnik Arystov and protopope Antoniy from Zhyvotov (possibly the Kiev Voivodeship).
