Stolberg-Stolberg was a county of the Holy Roman Empire located in the southern Harz region. Its capital was the town of Stolberg, now in Saxony-Anhalt, Germany. It was ruled by a branch of the House of Stolberg.
In 1429 the County of Wernigerode passed to the Counts of Stolberg, who ruled Wernigerode through a personal union. In 1548 the line was split between a Harz line (Stolberg-Stolberg) and a Rhenish line which had possessions in Rochefort (Stolberg-Rochefort) and Königstein im Taunus (Stolberg-Königstein).
With the death of Count Wolf Georg zu Stolberg in 1631, Stolberg-Stolberg was inherited by members of the Rhenish line. On 31 May 1645 Stolberg-Stolberg was divided between a senior Stolberg-Wernigerode line and a junior Stolberg-Stolberg line. In 1706, Stolberg-Stolberg divided again, with Stolberg-Rossla being created.
The children of Fürsten and Erbprinzen zu Stolberg-Wernigerode bore the title Prince[ss] (Prinz[essin]) zu Stolberg-Wernigerode and were styled Serene Highness. Other members of this line bore the title Count[ess] (Graf/Gräfin) zu Stolberg-Wernigerode, with the style Illustrious Highness.
