Peter Ferdinand was the fourth child and third-eldest son ofFerdinand IV, Grand Duke of Tuscany and his wifeAlice of Bourbon-Parma.[citation needed] His two elder brothers married morganatically. While his father had kept the title ofGrand Duke of Tuscany after the abolition of the dukedom in 1860, he had abdicated it in favor of the Austrian Emperor in 1870.[1] Peter Ferdinand did not pretend to the title of grand duke himself.[2][3]The former Prime Minister of Saxony and later Imperial and Household MinisterBeust declared: ‘The Tuscan Grand Ducal family has lost its sovereign rights as a result of political events. This branch of the Austrian imperial family is therefore naturally subordinate to the rights and duties of all other members of the imperial family. The Grand Dukes Leopold and Ferdinand and their more famous brothers are therefore from now on to be considered only as Archdukes of Austria and to be treated in accordance with the Statute of the High Noble Family of 3 February 1839."[4]
Peter Ferdinand had a career in the army. In 1908 he was a colonel, in 1911 major general and on 23 April 1914 he was promoted toFeldmarschall-Leutnant. At the outbreak of World War I in August 1914, he was commander of the 25th Infantry Division, with which he fought againstRussia inGalicia and southern Poland, as part of the Austro-Hungarian II Corps. GeneralMoritz von Auffenberg later blamed Peter Ferdinand's actions for preventing the encirclement of the entire5th Russian army during theBattle of Komarów (1914). In June 1915, Peter Ferdinand was relieved of command and the 25th Division was taken over by Major General Joseph Poleschensky.

^Rivista Araldica, anno 1913, volume 11, pagina 381, Roma, Collegio Araldico: " Da informazione ufficiale assunta a Vienna togliamo quanto segue «A Sua Altezza I. R. il defunto Granduca Ferdinando IV di Toscana era stato permesso dall'Impero austro-ungarico e dagli Stati dell'Impero germanico, di conferire i tre Ordini toscani, inerenti alla Sovranità, che anche spodestato, rimase all'Augusto principe fino alla sua morte. Il titolo di Principe di Toscana fu solo autorizzato ai membri della famiglia granducale nati prima del 1866. Dopo la morte del Granduca (1908) tutti gli augusti figli del defunto dovettero solennemente rinunciare ad ogni qualsiasi diritto di cui personalmente ed eccezionalmente godeva il padre. Quindi il Gran Magistero dell'Ordine di S. Stefano per volontà di S. M. l'Imperatore e Re è terminato col defunto granduca, né più sarebbe accettato dagli augusti principi lorenesi" (in Italian)
