Ernest Renan was an armored cruiser built for the French Navy in the first decade of the 20th century. At the outbreak of World War I in August 1914, she participated in the hunt for the German battlecruiser SMS Goeben and then joined the blockade of the Austro-Hungarian Navy in the Adriatic. She took part in the Battle of Antivari later in August, and the seizure of Corfu in January 1916, but saw no further action during the war. After the war, the British and French intervened in the Russian Civil War; this included a major naval deployment to the Black Sea, which included Ernest Renan. She served as a training ship in the late 1920s before she was sunk as a target ship in the 1930s.

The Battle of Antivari or Action off Antivari was a naval engagement between a large fleet of French and British warships and two ships of the Austro-Hungarian navy at the start of the First World War. The old Austrian protected cruiser SMS Zenta and the destroyer SMS Ulan were blockading the Montenegrin port of Antivari, when on 16 August 1914, they were surprised and cut off by a large Anglo-French force that had sortied into the Adriatic. Zenta fought and was destroyed, to give Ulan a chance to escape, which she did. The ships of the Austrian fleet at Cattaro, unaware of events, did not come out of port to meet the Allied fleet. After blockading the Adriatic for a short while the French were forced to withdraw due to a lack of supplies.
