Coat of arms description: five times divided by silver and red

Beichlingen was first mentioned in 860 on the occasion of a major donation to the monastery of Fulda. In the seventh decade of the 11th century it was owned by Otto of Meissen from the House of Weimar, through whose widow it passed to Dedi of Wettin. Through further marriages with the respective owners, Beichlingen also belonged temporarily to Otto of Northeim's son and Wiprecht II of Groitzsch. When, in the middle of the 12th century, inheritance in the male line had again become possible, one could speak of the dynasty of the Counts of Beichlingen. In addition to the Fuldian estates, the sovereign estates also passed completely into the possession of this family, although the feudal dependence on the Wettins was preserved. Only weak beginnings of a sovereignty of their own could be observed. In part, the Counts of Beichlingen exercised important functions in the surroundings of the Dukes and Electors of Saxony. In 1519 they were forced to sell all their possessions to the v. Werthern. Nevertheless, now completely impoverished and totally dependent on the Wettins, they still appeared in 1521 in 4 of the imperial registers, to which Elector Frederick (the Wise) and Duke John (the Steadfast) objected. The Albertine electors, who had had feudal sovereignty since 1547, respected a certain independence of the county internally, but represented it in the place of the v. Werthern vis-à-vis the empire.

From about the middle of the 13th century, the Counts of Beichlingen abandoned their official coat of arms, an eagle, which had initially been used as the imperial burgraves of Kyffhausen since about 1210, in favour of a shield divided three times. The oldest record is for 1253. In the middle of the 14th century, they temporarily reinstated the eagle in a squared coat of arms. The oldest tradition - including the Constance coat of arms book - agrees on the blazoning "three times divided by silver and red". Frequently, the divisions are also replaced by red or silver bars.
