Slam Râmnic County dates back to the period of the medieval organization of Wallachia. At first, the county's seat was at Focșanii Munteni, located on the right bank of the Milcov River, separating it from the city of Focșani proper that belonged to Moldavia. In 1542, when the Ottoman Empire annexed Brăila and its surrounding area, Slam Râmnic County received the rest of the territory previously administered by Brăila. In 1862, with the establishment of the Romanian state, entailing the political unification of Wallachia with Moldavia, the seat of the county was moved to Râmnicu Sărat, because it was a bigger trade centre in the middle of the county and renamed to Râmnicu Sărat, after the town. Focșanii Munteni was also joined with Focșani on the Moldavian side, becoming the seat of Putna County. The buildings in Râmnicu Sărat in which the county institutions functioned were properly purchased and equipped until 1900. In 1938, the county was disestablished and incorporated into the newly formed Ținutul Dunării, but it was re-established in 1940 after the fall of Carol II's regime - only to be abolished on 6 September 1950 by the Communist regime. The county was disbanded in administrative reforms of Communist Romania 1950, its southern area, including the county seat, was included in Regiunea Buzău, which itself was included after two years into Regiunea Ploiești in which the Râmnicu Sărat rayon was constituted; most of the county's north went to Regiunea Putna and then afterward to Regiunea Bârlad, whilst a small part of the eastern area passed to Regiunea Galaţi. The northern areas were also passed in their turn in 1960 to Regiunea Galaţi. In 1968, when Romania returned to county organization, Râmnicu Sărat County was not re-established.
