After Napoleon's campaign in Italy, Novara became the capital of the Department of the Agogna, but was then reassigned to the House of Savoy in 1814. In 1821, it was the site of a battle in which regular Sardinian troops defeated the Piedmontese constitutional liberals. In the even larger Battle of Novara in 1849, the Sardinian army was defeated by the Austrian army of Field Marshal Joseph Radetzky von Radetz. This defeat led to the abdication of Charles Albert of Sardinia and to the partial occupation of the city by the Austrians. The defeat of the Sardinians can be seen as the beginning of the Italian unification movement.
