Krasny Sulin
The place later called Krasny Sulin began as a small landed settlement on the Kundryuchya River. On 25 September 1797 the Don military administration authorised Colonel Andrey Lukich Sulin to establish a khutor near the mouth of the Gnilusha. The grant linked the riverbank site to military service and to the settlement policies of the Don Host.
The instructions also concerned the use of the land: Sulin was to maintain and grow woodland within the allotted stretch. The settlement initially housed twelve families of serfs purchased in Russia's central provinces. A few versts north, beside the Little Gnilusha, a winter livestock station supported a substantial herd of horses and was worked by three further families. These were farming and stock-raising estates, dependent on coerced peasant labour. They formed the local background before industrial development transformed the district much later. The early nineteenth-century settlement therefore belonged to a riverine estate landscape, where a Cossack officer's grant, peasant households and seasonal animal husbandry brought different obligations together.
