SMS Zrínyi, one of the last pre-dreadnoughts built by the Austro-Hungarian Navy, was launched in Trieste.

SMS Zrínyi was a Radetzky-class semi-dreadnought battleship (Schlachtschiff) of the Austro-Hungarian Navy, named for the Zrinski, a Croatian-Hungarian noble family. Zrínyi and her sisters, Erzherzog Franz Ferdinand and Radetzky, were the last pre-dreadnoughts built for the Austro-Hungarian Navy.

Pre-dreadnought battleships were sea-going battleships built from the mid- to late- 1880s to the early 1900s. Their designs were conceived before the appearance of HMS Dreadnought in 1906 and their classification as "pre-dreadnought" is retrospectively applied. In their day, they were simply known as "battleships" or else more rank-specific terms such as "first-class battleship" and so forth. The pre-dreadnought battleships were the pre-eminent warships of their time and replaced the ironclad battleships of the 1870s and 1880s.

The Austro-Hungarian Navy or Imperial and Royal War Navy was the naval force of Austria-Hungary. Ships of the Austro-Hungarian Navy were designated SMS, for Seiner Majestät Schiff. The k.u.k. Kriegsmarine came into being after the formation of Austria-Hungary in 1867, and ceased to exist in 1918 upon the Empire's defeat and subsequent collapse at the end of World War I.
