The Battle of the Alps was the first major engagement by a state which abandoned its monarchy in what year?
Kingdom of Italy The Kingdom of Italy (Italian: "Regno d'Italia" ) was a state which existed from 1861, when King Victor Emmanuel II of Sardinia was proclaimed King of Italy, until 1946, when a constitutional referendum led civil discontent to abandon the monarchy and form the Italian Republic. The state was founded as a result of the unification of Italy under the influence of the Kingdom of Sardinia, which can be considered its legal predecessor state.
Bassano 1796 Campaign Order of Battle In the Battle of Bassano on 8 September 1796, Napoleon Bonaparte and his French Army of Italy routed an Austrian army led by Dagobert Sigmund von Wurmser. Afterward, Wurmser gathered the intact parts of his army and marched for Mantua. On 15 September, the French defeated the Austrians and drove them into the fortress. This raised the numbers of the underfed and malaria-ridden garrison to nearly 30,000 men. These actions and the Battle of Rovereto occurred during the second attempted relief of the Siege of Mantua.
