Beichlingen
Beichlingen was a Thuringian county centred on Beichlingen Castle and held as a fief of the Thuringian landgraves. Count Frederick ruled in 1337, after debt had already forced the family to sell Heringen Castle around 1330.
In 1448 the counts pledged much of their land to Stolberg and Schwarzburg; it passed to them in 1457 and to Stolberg alone in 1468. Count Adam sold the remaining county and castle to Hans von Werthern in 1519, and the family died out in the male line in 1567.
