Principality of Reuss-Greiz: History of the Elder Line
The Principality of Reuss-Greiz, later known as the Principality of Reuss Elder Line, was a sovereign state within the German Empire. Ruled by the House of Reuss, this territory played a distinct role in the complex political landscape of Thuringia. Established in 1778 when the Counts of Reuss (specifically those of Greiz, Lower-Greiz, and Upper-Greiz) were elevated to princely status, the state remained under the rule of the Elder Line until the end of the monarchy in 1918.
One of the most peculiar traditions of the House of Reuss was the naming convention of its male members. In honor of Emperor Heinrich VI, who had historically benefited the family, every male member of the house was named Heinrich. To distinguish between individuals, they were numbered sequentially by birth rather than by their order of reign. This system continued through the final series, which began with Heinrich I (born 1693) and concluded with Heinrich XXIV.

Political Structure and Governance
The principality was governed by a Prince, supported by a Minister of State. The administration saw long tenures, such as that of Franz von Grün, the first Minister of State who served from 1782 to 1833, and Ernst von Meding, the final minister who served from 1901 until the state's dissolution in 1918.
Chronology of Princes
The leadership of the Elder Line was characterized by a succession of princes named Heinrich:
- Heinrich XI (1778–1800)
- Heinrich XIII (1800–1817)
- Heinrich XIX (1817–1836)
- Heinrich XX (1836–1859)
- Heinrich XXII (1859–1902)

Territorial Evolution and Legacy
Following the events of World War I, the political structure of the region shifted dramatically. On November 11, 1918, the principality was disestablished. In 1919, the territory of the Elder Line merged with that of the Junior Line to form the People's State of Reuss. By 1920, this new entity was incorporated into the state of Thuringia.
The Elder Line officially became extinct in 1927 upon the death of the childless Heinrich XXIV, at which point any remaining claims passed to the Junior Line.
