Given the question: Information: - The Second Punic War, also referred to as The Hannibalic War and (by the Romans) the War Against Hannibal, lasted from 218 to 201 BC and involved combatants in the western and eastern Mediterranean. This was the second major war between Carthage and the Roman Republic and its allied Italic socii, with the crucial participation of Numidian-Berber armies and tribes on both sides. The two states fought three major wars with each other over the course of their existence. They are called the "Punic Wars" because Rome's name for Carthaginians was "Poeni", derived from "Poenici" (earlier form of "Punici"), a reference to the founding of Carthage by Phoenician settlers. - The First Punic War (264 to 241 BC) was the first of three wars fought between Ancient Carthage and the Roman Republic. For more than 20 years, the two powers struggled for supremacy, primarily on the Mediterranean island of Sicily and its surrounding waters, and also in North Africa. The war signaled the beginning of a strategic transformation in the western Mediterranean. Carthage began the war as the great sea-power of the western Mediterranean, while Rome had but a small fleet of fighting ships. Over the course of the war, Rome built up a powerful navy, developed new naval tactics, and strategically used their navy, army, and local political alliances on Sicily in order to achieve a victory that expelled the Carthaginians from Sicily. The First Punic War ended with a treaty between Rome and Carthage, but years of bloodshed were to follow in the Second and Third Punic Wars before the strategic issue of power in the western Mediterranean was resolved in favor of Rome, and in the total destruction of Carthage. - Hispania Ulterior (English: "Further Spain", or occasionally "Thither Spain") was a region of Hispania during the Roman Republic, roughly located in Baetica and in the Guadalquivir valley of modern Spain and extending to all of Lusitania (modern Portugal, Extremadura and a small part of Salamanca province) and Gallaecia (modern Northern Portugal and Galicia). Its capital was Corduba. - Lusitania or Hispania Lusitana was an ancient Iberian Roman province including approximately all of modern Portugal south of the Douro river and part of modern Spain (the present autonomous community of Extremadura and a small part of the province of Salamanca). It was named after the Lusitani or Lusitanian people (an Indo-European people). Its capital was "Emerita Augusta" (currently Merida, Spain), and it was initially part of the Roman Republic province of Hispania Ulterior, before becoming a province of its own in the Roman Empire. Romans first came to the territory around the mid 2nd century BC. A war with Lusitanian tribes followed, from 155 to 139 BC. In 27 BC, the province was created. - Tarraco is the ancient name of the current city of Tarragona (Catalonia, Spain). It was the oldest Roman settlement on the Iberian Peninsula, founded during the Second Punic War by Scipio Calvus, and became capital of the Roman province of Hispania Citerior, and of Hispania Tarraconensis during the Roman Empire. - Hannibal (247 between 183 and 181BC), fully HannibalBarca, was a Punic military commander from Carthage, generally considered one of the greatest military commanders in history. His father Hamilcar Barca was the leading Carthaginian commander during the First Punic War. His younger brothers were Mago and Hasdrubal, and he was brother-in-law to Hasdrubal the Fair. - Hispan, Espan, Hispalo or Hispano, is a mythological character of Antiquity, who would derive the name Hispania, according to some ancient writers. Therefore, Hispan is the eponymous hero of Hispania. Hispan is mentioned first by the Gallo-Roman historian Gnaeus Pompeius Trogus (1st century BC) in his work "Historiae Philippicae", preserved only in a later summary, probably made in the 3rd century AD by Justinus. During the Middle Ages, Hispan was also known as Espan, told of him various legends. - Gallaecia or Callaecia, also known as Hispania Gallaecia, was the name of a Roman province in the north-west of Hispania, approximately present-day Galicia, northern Portugal, Asturias and Leon and the later Suebic Kingdom of Gallaecia. The Roman cities included the port Cale (Porto), the governing centers Bracara Augusta (Braga), Lucus Augusti (Lugo) and Asturica Augusta (Astorga) and their administrative areas Conventus bracarensis, Conventus lucensis and Conventus asturicensis. - Hispania Citerior (English: "Hither Spain", or "Nearer Spain") was a Roman Province in Hispania during the Roman Republic. It was on the eastern coast of Spain down to the town of Cartago Nova, today's Cartagena in the autonomous community of Murcia, Spain. It roughly covered today's Spanish autonomous communities of Catalonia and Valencia. Further south there was the Roman Province of Hispania Ulterior ("Further Spain"), which further away from Rome. The two provinces were formed in 197 BC, four years after the end of the Second Punic War (218-201 BC). During this war Scipio Africanus defeated the Carthaginians at the Battle of Ilipa (near Seville) in 206 BC. This led to the Romans taking over the Carthaginian possessions in southern Spain and on the east coast up to the River Ebro. Several governors of Hispania Citerior commanded wars against the Celtiberians who lived to the west of this province. In the late first century BC Augustus reorganised the Roman provinces in Hispania and Hispania Citerior was replaced by the larger province of Hispania Tarraconensis, which included the territories the Romans had conquered in central, northern and north-western Hispania. Augustus also renamed Hispania Ulterior Hispania Baetica and created a third province, Hispania Lusitania. - The Iberian Peninsula , also known as Iberia, is located in the southwest corner of Europe. The peninsula is principally divided between Portugal and Spain, comprising most of their territory. It also includes Andorra and a small part of France along the peninsula's northeastern edge, as well as Gibraltar on its south coast, a small peninsula which forms an overseas territory of the United Kingdom. With an area of approximately , it is the second largest European peninsula, after the Scandinavian. - The Balearic Islands are an archipelago of Spain in the western Mediterranean Sea, near the eastern coast of the Iberian Peninsula. - Hasdrubal the Fair (c. 270 BC 221 BC) was a Carthaginian military leader and politician, governor in Iberia after Hamilcar Barca's death, and founder of Cartagena. - Hispania was the Roman name for the Iberian Peninsula. Under the Republic, Hispania was divided into two provinces: Hispania Citerior and Hispania Ulterior. During the Principate, Hispania Ulterior was divided into two new provinces, Baetica and Lusitania, while Hispania Citerior was renamed Tarraconensis. Subsequently, the western part of Tarraconensis was split off, first as Hispania Nova, later renamed Callaecia (or Gallaecia, whence modern Galicia). From Diocletian's Tetrarchy (AD 284) onwards, the south of remaining Tarraconensis was again split off as Carthaginensis, and probably then too the Balearic Islands and all the resulting provinces formed one civil diocese under the "vicarius" for the Hispaniae (that is, the Celtic provinces). The name, Hispania, was also used in the period of Visigothic rule. - The Roman Republic was the era of ancient Roman civilization beginning with the overthrow of the Roman Kingdom, traditionally dated to 509 BC, and ending in 27 BC with the establishment of the Roman Empire. It was during this period that Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean world. - Publius Cornelius Scipio (died 211 BC) was a general and statesman of the Roman Republic. - Hasdrubal Barca (245207 BC) was Hamilcar Barca's second son and a Carthaginian general in the Second Punic War. He was the brother of the famous Hannibal. - The Battle of the Upper Baetis was a double battle , comprising the battles of Castulo and Ilorca , fought in 211 BC between a Carthaginian force led by Hasdrubal Barca ( Hannibal 's brother ) and a Roman force led by Publius Cornelius Scipio and his brother Gnaeus . The immediate result was a Carthaginian victory in which both Roman brothers were killed . Before this defeat , the brothers had spent seven years ( 218BC - 211BC ) campaigning in Hispania , which had limited the resources available to Hannibal , who was simultaneously fighting the Romans in Italy . This double battle also represents the only Carthaginian victory in a major land battle during the Second Punic War in which Hannibal was not in command of the Carthaginian armies .
