 On 29 September 1911, Italy declared war on the Ottoman Empire in order to seize Libya. Emanuele Filiberto served in the 3rd Division, which she joined on 30 September. She served alongside Ammiraglio di Saint Bon and the two Regina Margherita-class battleships. The ship took part in the bombardment of the fortresses defending Tripoli on 3 October. Italian soldiers went ashore two days later, and by the 11th, they had taken the city. In December, she was stationed in Italy.
