Despite the abolition of the monarchy in 1918, the House of Hohenzollern never relinquished their claims to the thrones of Prussia and the German Empire. These claims are linked by the Constitution of the German Empire: according to this, whoever was King of Prussia was also German Emperor. However, these claims are not recognised by the Federal Republic of Germany or anyone else, this included the Weimar Republic, Nazi Germany and West or East Germany. In 1933 Prince William renounced his claim to the former throne when he married Dorothea von Salviati, in 1940 William II accepted Dorothea and his daughters Felicitas and Christa as dynastic members thus styled HRH Dorothea, Princess of Prussia, HRH Felicitas, Princess of Prussia and HRH Christa, Princess of Prussia, Prince William was killed in 1940. Prince Louis Ferdinand who was third in line of the succession by 1933, his first son Prince Friedrich Wilhelm renounced his claim in 1967 to marry Waltraud Freytag whom he divorced in 1975 and his second son Prince Michael renounced his claim in 1966 to marry Jutta Jörn like his brother he divorced her in 1982, then his third son Prince Louis Ferdinand of Prussia, jr. was involved in a severe accident during military maneuvers when he was pinned between two vehicles. Although his leg was amputated, he succumbed several weeks later to the trauma and died in 1977. Prince George Frederick inherited from his grandfather, and during his time as head of House of Hohenzollern his two uncles Princes Friedrich Wilhelm and Michael challenged him to a lawsuit claiming that, despite their renunciations as dynasts at the time of their marriages, the loss of their inheritance rights based on their selection of spouse was discriminatory and unconstitutional. His uncles were initially successful, the Regional Court of Hechingen and the higher Regional Court of Stuttgart ruling in their favour in 1997 on the grounds that the requirement to marry equally was "immoral". However, the Federal Court of Justice of Germany overturned the original rulings in favour of Georg Friedrich's uncles, the case being remanded to the courts at Hechingen and Stuttgart. This time both courts ruled in favour of Georg Friedrich. His uncles then took their case to the Federal Constitutional Court of Germany which overruled the previous court rulings in Georg Friedrich's favour. On 19 October 2005, a German regional court ruled that Georg Friedrich was indeed the principal heir of his grandfather, Louis Ferdinand, but also concluded that each of the children of Louis Ferdinand was entitled to a portion of the Prussian inheritance.
