Heinrich XXII, Prince Reuss of Greiz

Heinrich succeeded as reigning Prince Reuss of Greiz after the death of his father on 8 November 1859.[3] As Heinrich was a mere thirteen years of age, his mother Caroline of Hesse-Homburg (1819-1872) served as regent until his majority at the age of 21. As the daughter of an Austrian general and the wife of an Austrian officer, Caroline was vehemently anti-Prussian. As a result, during the Austro-Prussian War, Reuss was occupied by Prussian troops, who remained until a payment of 100,000 thalers was made.

On 28 March 1867, Heinrich took the reins of government into his own hands. Upon taking full power, he gave his principality its first constitution. Like his parents, Heinrich remained anti-Prussian his entire life, repeatedly rejecting Prussian measures such as Kulturkampf and the creation of civil marriages. Heinrich, as well as his subjects in Reuss, refused fully to accept that the Hohenzollern German Emperors had precedence over other royal houses. For instance, when asked about his relationship with the Emperor, Heinrich would simply respond that they "were allies for the common defense of the German Federation".[4] Heinrich lost no opportunity to displease the Emperor, declining to permit the construction of any memorial to Emperor Wilhelm I, Wilhelm II's beloved grandfather but this was later forced upon him.[5] Heinrich also refused to tolerate any demonstrations of mourning, either official or in private, when the deaths of emperors Wilhelm I and Frederick III occurred, and forbade any celebration of the anniversaries of the German victories of 1870 but this was done any way and could not be punished and was ignored and punishment not enforced and done anyway .[5]

Heinrich was very wealthy, as the greater part of the territory he ruled over was his private property.[2][6] At the end of his rule, Reuss contained fewer than 70,000 people, and comprised an area of 122 square miles.[3][4]

On 8 October 1872, he married Princess Ida of Schaumburg-Lippe, a daughter of Adolf I, Prince of Schaumburg-Lippe.[1][2][6] They had the following children:

• Heinrich XXIV, Prince Reuss of Greiz (1878–1927)
• Princess Emma (1881–1961) ∞ (1903) Count Erich Künigl von Ehrenburg (1880–1930)
• Princess Marie (1882–1942) ∞ (1904) Baron Ferdinand von Gnagnoni (1878–1955)
• Princess Caroline (1884–1905) ∞ (1903) Wilhelm Ernst, Grand Duke of Saxe-Weimar-Eisenach (1876–1923)
• Princess Hermine (1887–1947) ∞ I. (1907) Prince Johann Georg of Schoenaich-Carolath (1873–1920); ∞ II. (1922) Ex-Kaiser Wilhelm II (1859–1941)
• Princess Ida (1891–1977) ∞ (1911) Fürst Christoph Martin III. zu Stolberg-Roßla (1888–1949)

Prince Heinrich died of heart trouble on 19 April 1902.[1][3] His death meant his mentally and physically disabled only son Prince Heinrich became reigning prince of Reuss.[5] As the prince was clearly unable to fulfill these duties, arrangements for a regency were made. A younger branch of the Reuss family was next-in-line to the title, but there was some concern that Heinrich might choose another for the regency, as he disliked them.[5] In the end, Heinrich's distant cousin Prince Heinrich XXVII of Reuss zu Schleiz was chosen; his wife, Princess Elise of Hohenlohe-Langenburg was a cousin of both Kaiser and his wife Empress Augusta Viktoria, and the prince himself had served alongside Emperor Wilhelm in the regiment of the Hussars of the Guard, thus repairing relations between the houses of Hohenzollern and Reuss.[5]
