Beuron Abbey gained possession of Bärenthal in 1751. It became a possession of the Principality ofHohenzollern-Sigmaringen in 1803 and was assigned toOberamt Beuren [de] until 1820 and thenOberamt Wald [de] until 1860. In 1938, the district of Wald was dissolved and Bärenthal was assigned to the newly createdLandkreis Sigmaringen. This district, too, was abolished in the1973 Baden-Württemberg district reform [de] and Bärenthal was placed in the newly organized district ofTuttlingen. The village grew to about its present size in 1960 and has, since 1999, been the least-populated municipality in the district of Tuttlingen.[3]
Bärenthal'scoat of arms is divided into twofields: the upper field isyellow and contains a bluebear, walking to the left, while the lower isblue and contains a yellow "b" whose stem is crossed. The bear is afolk etymological reference to the Bära river as the origin of "Bärenthal", and the crossed "b" to Beuron Abbey, from whom the blue-yellowtincture is also derived. This coat of arms was first proposed by theSigmaringen State Archive [de] in 1947 and was accepted by the municipal council in 1954. Official use was approved on 8 May 1973 by theFederal Ministry of the Interior, who also issued a municipal flag to Bärenthal on that date.[3]
