Germany

The German Empire was a federation of myriad smaller monarchies, all of which are now abolished under modern republican Germany. As a result, there are a large number of claimants to various German thrones. Since the dissolution of the empire, however, a number of former royal households have become extinct in the male line, and are therefore not represented in the list below. Mecklenburg-Schwerin went extinct in 2001, Saxe-Altenburg in 1991, and Schwarzburg-Rudolstadt and Schwarzburg-Sondershausen in 1971.

Italy

Up until the 19th century, the Italian peninsula comprised a number of states, some of which were monarchies. During the Italian unification, the monarchs of such agglomerated states lost their sovereignty and their titles became purely ceremonial. The resultant throne of the Kingdom of Italy was held by the former king of Sardinia.

Croatia
Upon independence in 1941, a puppet monarchy of Italy was instituted in Croatia, with Prince Aimone of the House of Savoy appointed king. Aimone accepted the nomination in May 1941, adopting the regnal name "Tomislav II". In July 1943, however, he was forced to abdicate his throne on the orders of the Italian king Vittorio Emanuele III, before ever having been crowned. Aimone formally renounced all claims in October 1943. Since his death on 29 January 1948, his eldest son Amedeo may be argued to be the heir to that throne,[135] although he does not advance the claim.[126] If reigning, he would be known as "Zvonimir II".[135] However, the Habsburg claim is normally considered the primary one in regard to Croatia (see under "Austria-Hungary", above).

Finland In 1918, following Finland's independence from Russia, the national parliament made an attempt to establish a monarchy under the reign of a German king. Prince Friedrich Karl, of the House of Hesse, was elected as King of Finland in October 1918. He renounced this throne two months later, without ever having taken up the position, and Finland subsequently adopted a republican constitution. For this reason, there is a dispute as to whether the House of Hesse may lay claim to this title, as many maintain that since the king-elect was never installed, the title was never officially bestowed, and thus no claim has any legal basis. The order of succession to the throne was never established, but following the desire to the keep the throne separate from the senior line of the family, the current heir (since 18 November 1999) would be Phillipp, the great grandson of Friedrich Karl.[136]

Ireland
The Chiefs of the Name are the hereditary chieftains of the Irish clans, who are directly descended from the Gaelic royal families which ruled in parts of Ireland until the beginning of the seventeenth century. Most prominent among these are:[137]





Lithuania Following the country's independence from Russia in 1918, the Council of Lithuania voted to establish a monarchy, and invited Prince Wilhelm, the Duke of Urach,[eu 33] to take the throne as king. Wilhelm accepted the nomination in July 1918, and adopted the regnal name "Mindaugas II". During the subsequent German Revolution, however, the Council withdrew its decision in November 1918, and Wilhelm was never crowned. His grandson, Wilhelm Albert is the current head of the family since 9 February 1991. In 2009, the Duke of Urach's brother Prince Ingio of Urach visited Lithuania and announced that if offered the throne he would be ready to assume it.[145]
