The Bolivian war of independence began in 1809 with the establishment of government juntas in Sucre and La Paz, after the Chuquisaca Revolution and La Paz revolution. These Juntas were defeated shortly after, and the cities fell again under Spanish control. The May Revolution of 1810 ousted the viceroy in Buenos Aires, which established its own junta. Buenos Aires sent three military campaigns to the Charcas, headed by Juan José Castelli, Manuel Belgrano and José Rondeau, but the royalists ultimately prevailed over each one. However, the conflict grew into a guerrilla war, the War of the Republiquetas, preventing the royalists from strengthening their presence. After Simón Bolívar and Antonio José de Sucre defeated the royalists in northern South America, Sucre led a campaign that was to defeat the royalists in Charcas for good when the last royalist general, Pedro Antonio Olañeta, suffered death and defeat at the hands of his own defected forces at the battle of Tumusla. Bolivian independence was proclaimed on August 6 of 1825.

The Battle of Fort Point Peter was a successful attack in early 1815 by a British force on a smaller American force on the Georgia side of the St. Marys River near St. Marys, Georgia. The river was then part of the international border between the United States and British-allied Spanish Florida; it now forms part of the boundary between Georgia and Florida. Occupying coastal Camden County allowed the British to blockade American transportation on the Intracoastal Waterway. The attack on Forts St. Tammany and Peter occurred in January 1815, after the signing of the Treaty of Ghent, which would end the War of 1812, but before the treaty's ratification. The attack occurred at the same time as the siege of Fort St. Philip in Louisiana and was part of the British occupation of St. Marys and Cumberland Island.

During the period known as the Hundred Days Napoleon chose to confront the armies of Prince Blücher and the Duke of Wellington in what has become known as the Waterloo Campaign. He was decisively defeated by the two allied armies at the Battle of Waterloo, which then marched on Paris forcing Napoleon to abdicate for the second time. However Russia, Austria and some of the minor German states also fielded armies against him and all of them also invaded France. Of these other armies the ones engaged in the largest campaigns and saw the most fighting were two Austrian armies: The Army of the Upper Rhine and the Army of Italy.

The Neapolitan War was a conflict between the Napoleonic Kingdom of Naples and the Austrian Empire.

The battle took place near the strategic crossroads of Quatre Bras and was contested between elements of the Duke of Wellington's Anglo-allied army and the left wing of Napoleon Bonaparte's French Armée du Nord under Marshal Michel Ney.

William Shaler was the US commissioner in Algiers who had negotiated alongside Decatur, but he fled aboard British vessels during the Bombardment of Algiers (1816). He negotiated a new treaty in 1816 which was not ratified by the Senate until February 11, 1822, because of an oversight.

The Second Serbian Uprising was the second phase of the Serbian Revolution against the Ottoman Empire, which erupted shortly after the re-annexation of the country to the Ottoman Empire in 1813. The occupation was enforced following the defeat of the First Serbian Uprising (1804–1813), during which Serbia existed as a de facto independent state for over a decade. The second revolution ultimately resulted in Serbian semi-independence from the Ottoman Empire. The Principality of Serbia was established, governed by its own parliament, constitution and royal dynasty. De jure independence, however, was attained in 1878, following the decisions of the Congress of Berlin.
