The Sack of Genoa happened between Thursday April 5 and Wednesday April 11, 1849. Genoa was then part of the Kingdom of Piedmont-Sardinia, but had only become so comparatively recently, after the defeat of Napoleon. The uprising broke out in Genoa after King Vittorio Emanuele II (succeeding his father Carlo Alberto after the defeat of Novara) signed the armistice with the Austrian general Joseph Radetzky on March 25. When the occupation was done, Vittorio Emanuele II thanked the General La Marmora with a letter.
