Heinrich XIII Prinz Reuss

In August 2022, Reuss attended an official reception held by Thomas Weigelt the mayor of Bad Lobenstein, where Reuss' hunting lodge Jagdschloss Waidmannsheil is located. Weigelt was known to be to be sympathetic to the Reichsbürger movement and journalist Peter Hagen asked him why someone associated with the Reichsbürger scene like Reuss would be invited to an official event. The next day Hagen approached the mayor at the market festival and tried to film him in familiar conversation with Reuss and AfD-politician Uwe Thrum [de]. Filming the trio led to a violent attack by Weigelt on the journalist, which was captured on film. After injuring the journalist (who had to be treated in hospital) and damaging his equipment, Weigelt refused to resign and was suspended from office.

On 7 December 2022, Reuss was arrested at his home in the Westend district of Frankfurt during an extensive raid of alleged far-right conspirators planning a coup d'état. According to police, the coup's conspirators—which included former Bundestag member Birgit Malsack-Winkemann—were proponents of the Reichsbürger movement who hoped to install the 71-year-old Reuss as head of state. Reuss' hunting lodge Jagdschloss Waidmannsheil in Saaldorf, Thuringia was allegedly the site of weapons stockpiles and meetings regarding the conspiracy.

Heinrich XIV Fürst Reuss distanced himself and his family again after Reuss was arrested in 2022, calling Reuss a “confused old man” and "a marginal figure" and noting that their last common ancestor lived in the early 19th century. He said Reuss' behaviour was a "catastrophe" for the family, whose heritage as tolerant and cosmopolitan rulers was now associated with "terrorists and reactionaries". He believes Reuss' anti-government views derive from his resentment at the German judicial system for its failure to recognize his claims to family properties expropriated at the end of World War II.

Reuss spent much of his fortune on lawsuits seeking restitution, but with little success. He conducted court proceedings on behalf of his mother, who died in 2019, and obtained many artworks that were later sold at auction for 3.5 million marks while more than 300 pieces were lent to museums. In addition, he conducted court proceedings on behalf of his mother for former properties. However, he was not quite as unsuccessful in this as he claimed. In 2008, she obtained in a settlement the restitution of forest property and the restored Thallwitz Castle (formerly a hospital) in Saxony. He is said to it have inherited from her after persuading her to make him her sole heir - disinheriting his siblings. Today Thallwitz Castle is neglected. He ended up purchasing Jagdschloss Waidmannsheil in Bad Lobenstein from the state, from which he ran a hickory golf course. The hunting lodge is said to have served as a meeting place for the alleged conspirators.

On 22 December 2018, Reuss and his mother attended the unveiling of a "Flame of Peace" sculpture in Gera in honor of her 100th birthday by the heads of the Vienna-based Association for the Promotion of Peace. In 2020, Reuss participated in the celebration of the first International Day of Conscience event in Vienna.

In 2017, he supported the reinterment of the remains of a number of his ancestors, most prominent among them Henry II, Count of Reuss-Gera, in their original location. Their sarcophagi had been moved repeatedly since the church where they were entombed was destroyed in a fire in 1780.

The House of Reuss, from which Reuss is descended, dates to the 12th century and historically administered the regions of Gera and Greiz a non-contiguous mini-state in what is today Eastern Thuringia. Reuss left the family association at his own request around 2009.

Reuss married Iranian-born Susan Doukht Jalali in 1989, and they have two children, including a son named Heinrich XXVIII born circa 1991 and a daughter Elena who has Down syndrome and was born in 1989. The couple are divorced. His wife uses the name Princess Susan Reuss and works as a naturopath. She has served as Germany's attaché to UNESCO in support of its program Education for Children in Need. Reuss is also reported to have as a girlfriend a Russian national identified by prosecutors as "Vitalia B.", who allegedly had some role in the coup plot.

Heinrich XIII Prinz Reuss (born 4 December 1951; German: Heinrich XIII. Prinz Reuß, [ˈhaɪnʁɪç deːɐ̯ ˈdʁaɪ̯ˌt͡seːntə pʁɪnt͡s ʁɔɪ̯s]) is a German businessman, far-right and monarchist activist, and member of a former aristocratic family. A proponent of the Reichsbürger movement and antisemitic conspiracy theories, Reuss was arrested by German federal police in December 2022 due to his alleged leadership in the 2022 German coup d'état plot.

Reuss was born in Büdingen on 4 December 1951, the fifth of six children and the fourth son born to Prince Heinrich I Reuss and Duchess Woizlawa Feodora of Mecklenburg, who was in turn the only child of the German colonial politician Duke Adolf Friedrich of Mecklenburg. Reuss' parents, like all German nobility, had become private citizens in 1919 upon the adoption of the Weimar Constitution, which abolished any privileges and titles that had previously existed for nobility.

In 1945, the Communist land reform in the Soviet occupation zone (East Germany) expropriated all movable and immovable assets of the House of Reuss. Following the reunification of Germany in 1990, Reuss tried to have properties restituted. The clan, which consisted of five large families, wanted Gera townhouses, four castles, extensive forestry and agricultural property and the Jugendstil Reuss Theater in Gera, then held by the city of Gera in Thuringia. Concerning the theater, Reuss and the mayor of Gera were unable to negotiate an settlement, each blaming the other.

Many of Reuss' views are consistent with monarchism. He has called for "the revival of the legal structures" that existed before 1918, when the abolition of the monarchy "created so much suffering". He has spoken in favour of low flat tax for all citizens and against debt-based business models hailing the 10 percent rate in the former Principality of Reuss, saying it let Reuss's citizens lead "happy lives" because it was "straightforward and transparent". Reuss contended that the modern German government and European Union were more distant and inaccessible than feudal princes. Reuss also gave speeches claiming that Germany had been a vassal state since the Second World War. At World Web Forum in Zürich in 2019, Reuss gave a speech accusing the Rothschilds and Freemasons of responsibility for the wars of the 20th century, expressing antisemitic conspiracy theories. The speech left attendees "horrified", with some booing or leaving.
