He was born the son of a merchant at Trento, a city with a predominantly Italian-speaking population, which at the time was part of the Cisleithanian crown land of Tyrol in Austria-Hungary. Battisti attended the University of Florence, where he became a follower the Italian irredentism movement, aiming at the unification of his Trentino homeland with the Kingdom of Italy, though contrary to activists like Ettore Tolomei and Gabriele d'Annunzio he did not claim the predominantly German-speaking areas of South Tyrol up to the Brenner Pass. In 1899, he married Ernesta Bittanti in a civil ceremony. The couple had three sons. A journalist by profession and a member of the Social Democratic Workers' Party of Austria, he was elected as a representative to the Tyrolean Landtag assembly at Innsbruck as well as to the Austrian Imperial Council at Vienna in 1911, where he vainly tried to obtain a status of autonomy for the Trentino region. Disgruntled by Austro-Hungarian attitudes to minorities in their empire, Battisti agreed to construct a military guide for the Italians to Austrian provinces that bordered Italy. When Austria-Hungary mobilised in August 1914, Battisti fled with his family to the Kingdom of Italy, where he held public meetings demanding Italy join the Triple Entente forces against Austria. With Italy's entry into World War I following the 1915 London Pact, though still an Austrian citizen, Battisti fought against the Austro-Hungarian Army in the Alpini Corps at the Italian Front. in Rome After the Battle of Asiago, he and his 2nd Lt Fabio Filzi were captured by the Austrian forces on 10 July 1916 and faced a court-martial in his hometown Trento at the Castello del Buonconsiglio, charged with high treason. Though Battisti officially enjoyed parliamentary immunity, he was sentenced to death by strangulation. He requested a military execution by firing squad so as to not dishonor the Italian Army uniform, but the judge denied his request and instead procured for him some shabby civilian clothes. Dressed in these, he was executed the same day, the brutality of which was increased by the fact that executioner botched the job so that Battisti actually was hanged twice. The smiling execution squad posed with his body for photographs, which when later published did severe damage to Austria's reputation. The author Karl Kraus applied a picture as frontispiece of his 1922 play Die letzten Tage der Menschheit. Battisti is considered a national hero in Italy and several memorials were dedicated to him in Rome as well as in his hometown Trento and at the Bolzano Victory Monument. Both Trento and Bolzano had been under Austrian control until 1918.
