The Spanish government declared war to revolutionary France on April 17, 1793 in response to execution of the King and Queen of France. Spanish army under General Ricardos invaded France and occupied Rosellón in April1793. Spanish forces also took part in occupation of Toulon in 1793. Soon French General Dugommier fought back, recaptured all the territories lost and crossed the Pyrenees to invade Spain. French routed Spanish armies and occupied St Elmo, Collioure, PortVendres, Bellegarde, San Sebastian (General Dugommier killed during the siege), etc in 1793-1794. Treaty of Basel ended the war in 1795 and the alliance convention between France and Spain was signed in 1796.
The scale of the war in the Peninsula escalated as a Spanish victory over Dupont at Bailén in July was answered by Napoleon's arrival in Spain at the head of 200,000 veteran troops.
With Prussia re-entering the war against France on 16th March, Napoleon was unable to spare fresh troops for the Peninsula as he prepared to counter-attack in the east.
The last battle of the Peninsular War was fought on 10th April as Wellington cleared the French from the Calvinet Ridge overlooking the city of Toulouse.
The War of the Sicilian Vespers started with the insurrection of the Sicilian Vespers against Charles of Anjou in 1282 and finally ended with the peace of Caltabellotta in 1302.
It was fought in Sicily, Catalonia (the Aragonese Crusade) and elsewhere in the western Mediterranean between, on the one side, the Angevin claimants Charles of Anjou and his son, Charles II and the kings of France, their relatives, backed by the Papacy and, on the other side, the kings of Aragon.
Charles the elder arrived in Italy at that time, but died soon after in 1285 and the war in Italy was put on hold by the lack of leadership on both sides: Charles' successor was in chains and Peter was dealing with a new menace, the Aragonese Crusade.
