Reuss was the name of several historical states located in present-day Thuringia, Germany. Several lordships of the Holy Roman Empire which arose after 1300 and became Imperial Counties from 1673 and Imperial Principalities in the late 18th century were ruled by the House of Reuss.

Quedlinburg Abbey was a house of secular canonesses (Frauenstift) in Quedlinburg in what is now Saxony-Anhalt, Germany. It was founded in 936 on the initiative of Saint Mathilda, the widow of the East Frankish King Henry the Fowler, as his memorial. For many centuries it and its abbesses enjoyed great prestige and influence. Quedlinburg Abbey was an Imperial Estate and one of the approximately forty self-ruling Imperial Abbeys of the Holy Roman Empire. It was disestablished in 1802/3. The church, known as Stiftskirche St Servatius, is now used by the Lutheran Evangelical Church in Germany.
