1919–1938 Czechoslovakia — with the county town on the same sideČeskoslovensko — a stoličné mesto na tej istej strane

Sobrance became Czechoslovak in 1918–19, and for twenty years the arrangement worked, because Uzhhorod became Czechoslovak too, as the capital of the province of Subcarpathian Ruthenia. The administrative line between Slovakia and that province ran just east of the town, but it was an internal line, not a frontier: people, goods and business still moved along the old road. Sobrance was a district town in this period. It is the last time in the town's history that its natural centre and its own state were the same thing.Sobrance sa v rokoch 1918 – 1919 stali československými a dvadsať rokov to fungovalo, lebo československým sa stal aj Užhorod — ako hlavné mesto Podkarpatskej Rusi. Správna hranica medzi Slovenskom a touto krajinou viedla hneď východne od mesta, no bola vnútorná, nie štátna: ľudia, tovar aj obchod sa po starej ceste hýbali ďalej. Sobrance boli v tom čase okresným mestom. Je to naposledy v dejinách mesta, keď jeho prirodzené centrum a jeho vlastný štát boli tou istou vecou.
