Rijeka's port underwent tremendous development fuelled by generous Hungarian investments, becoming the main maritime outlet for Hungary and the eastern part of the Austro-Hungarian Empire. By 1913–14, the port of Fiume became the tenth-busiest port in Europe. The population grew rapidly from only 21,000 in 1880 to 50,000 in 1910. Major civic buildings constructed at this time include the Governor's Palace, designed by the Hungarian architect Alajos Hauszmann. There was an ongoing competition between Rijeka and Trieste, the main maritime outlet for Austria—reflecting the rivalry between the two components of the Dual Monarchy. The Austro-Hungarian Navy sought to keep the balance by ordering new warships from the shipyards of both cities.
