At the end of the 19th century, the Dichiseni commune was part of the Borcea locality of Ialomita County and consisted of the villages of Dichiseni, Coslogeni and Satnoeni, and of the Mandache and Putineiu domains, with a total of 1181 inhabitants. There were three churches (one in each village) and a mixed school with 65 pupils (of which nine were girls). The Socec Yearbook of 1925 records the commune in Fetesti of the same county, having 2178 inhabitants in the villages of Bratieni, Coslogeni, Dichiseni and Satnoeni.
In 1950, the commune went to the administration of the Fetesti district in the Ialomita region, then (after 1952) in the Constanţa region and (after 1960) in the Bucharest region. The village of Bratieni took the name Liberatatea during the communist regime. In 1968, the commune returned to Ialomita County (re-established), and the Libertatea village was forcibly decommissioned by the communist authorities in 1977 (although it continued to be included in the localities list). In 1981, a regional administrative reorganization led to the transfer of the commune to the Calarasi County.
