text_A: Venetia remained under Austrian control until the Austro-Prussian War in 1866, when the Kingdom of Italy joined on the Prussian side and was promised Venetia in exchange for its assistance. However, Austria refused to sell Venetia to Italy but the Italians saw this as a dishonourable act. This caused another southern front for Austria, the Third Italian War of Independence.
