One of the younger sub-lines of the branch which ruled the Reuss, J.L. until 1918, includes the "
Counts of
Plauen" from the late 19th century. When Prince Heinrich XXVI Reuss (1857–1913) married Countess Viktoria von Fürstenstein (1863–1949) in 1885, under the strict marriage rules then enforced by the Reuss dynasty, although he was but a younger son of a minor ruling family, their children were not allowed to bear the dynasty's princely title. They were, instead, designated "
Counts of
Plauen", although they remained in the line of succession to the two thrones of Reuss When the
German Empire collapsed at the end of
World War I, the reigning Prince Reuss lost his crown along with all the other monarchs whose realms were within Germany. In 1927, Henrich XXVI's son, known as Count Heinrich Harry of Plauen (1890–1951), was adopted by his childless uncle, Prince Heinrich XXX (1864–1939), and the now-deposed dynasty agreed to accept him as "Prince Heinrich Harry Reuß", along with those of his male-line descendants born of unions complying with the family's 1902 rules that permitted marriages to countesses (Heinrich Harry's wife, Huberta von Tiele-Winckler was only a baroness in her own right, but belonged to a family of
comital rank in
Prussia). Their son Heinrich Enzio was thus accepted by the House of Reuss as a prince, but his own marriage to Baron Gustaf
Peyron's daughter in 1949 occurred before the Reuss family conference of 1957 which lowered the marital standard again, allowing
dynastic inter-marriage with baronial families. In 1992, Prince Heinrich Ruzzo of Reuss, Count of Plauen, a prince of the former sovereign House of Reuss, married
Anni-Frid Lyngstad, a former lead singer of the popular 1970s Swedish musical group
ABBA. Since her marriage to the prince, she has held the titles of Princess Reuss and Countess of Plauen with the style of Her Serene Highness. Heinrich Ruzzo died of lymphoma on October 29, 1999, leaving her the titles of Dowager Princess and Countess. She currently resides in Genolier in the Canton of Vaud, Switzerland. She has shared a home since 2020 with her British partner,
Henry Smith, 5th Viscount Hambleden. Since 1999 the House of Reuss has recognized
Prince Heinrich Ruzzo Reuss of Plauen (German: Heinrich Ruzzo, Prinz Reuß von Plauen) by his formal title, though without official membership in the dynasty or entitlement to the traditional style of
Serene Highness. Under German law the title has been allowed only as part of the surname since 1919, thus the name "Heinrich Ruzzo Prinz Reuss."
