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.
