Principality of Reuss-Greiz The Principality of Reuss-Greiz (German: "Fürstentum Reuß-Greiz" ), called the Principality of the Reuss Elder Line (German: "Fürstentum Reuß älterer Linie" ) after 1848, was a sovereign state in modern Germany, ruled by members of the House of Reuss. The Counts Reuss of Greiz, Lower- and Upper Greiz (German: "Reuß zu Greiz, Untergreiz und Obergreiz" ), were elevated to princely status in 1778. Its members bore the title "Prince Reuss, Elder Line", or "Prince Reuss of Greiz". Similarly to the more numerous Reuss Younger Line, the male members of this house were all named "Heinrich", in honour of Heinrich VI who had benefited the family, and were numbered sequentially by birth, rather than by reign, the last series beginning with Heinrich I (born 1693) and ending with Heinrich XXIV (1878–1927).
