Description & Facts: Salamanca is a city in western Spain, the capital of the province of Salamanca, which belongs to the autonomous community of Castile and Leon (Castilla y Leon). The Old City was declared a UNESCO World Heritage Site in 1988. It lies about 200 km west of Madrid and 100 km east of the Portuguese border. With a population around 160,000 and with its metropolitan area the population rises to more than 200.000, also it is necessary to count the resident students, it is the third most populated city in Castile and Leon, following Valladolid. Salamanca is known both for its monumental sights and the University of Salamanca, which was founded in 1218 and is the oldest university in Spain and the fifth oldest western university. With its 30,000 students, the university is, together with tourism, the economic engine of the city. Salamanca is also known for the teaching of the Spanish language; in this field, Salamanca supplies 16% of the market within Spain and attracts thousands of foreign students. The city was founded in the pre-Ancient Rome period by the Vacceos, a Celtic tribe, as one of a pair of forts to defend their territory near the Duero river. In the third century BCE, Hannibal laid siege to the city. With the fall of the Carthaginians to the Romans, the city of Helmantica, as it was known, began to take more importance as a commercial hub in the Roman Hispania due to its favorable location. Salamanca lay on a Roman road, known as the Via de la Plata, which connected it with Emerita Augusta (present day Marida to the south and Asturica Augusta (present-day Astorga) to the north. The Roman bridge dating to the first century, was a part of this road. With the fall of the Roman Empire, the Alans established in Lusitania, and Salamanca was part of this region. Later the city was conquered by the Visigoths and included in their territory. The city was a already an episcopal see, and signatures of bishops of Salamanca are found in the Councils of Toledo. Salamanca surrendered to the Moors, led by Musa bin Nusair, in the year 712 CE. For years this area between the south of Duero River and the north of Tormes River, became the main battlefield against the Muslim invaders. The constant fighting of the Kingdom of Leon first, and the Kingdom of Castile and Leon later against the Caliphate depopulated Salamanca and reduced it to an unimportant settlement. After the battle of Simancas (939) the Christians resettled this area. After the capture of Toledo by Alfonso VI of Castile in 1085, the definitive resttlement of the city took place. Raymond of Burgundy, instructed by his father-in-law Alfonso VI of Leon, led a group of settlers of various origins in 1102. One of the most important moments in Salamanca's history was the year 1218, when Alfonso IX of Leon created the University of Salamanca. Soon it became one of the most significant and prestigious academic centres in Europe. In 1551 the Holy Roman Emperor Charles V ordered an inquiry to find out if the science of Andreas Vesalius, physician and anatomist, was in line with the Catholic doctrine. Vesalius came to Salamanca that same year to appear before the board and was acquitted. In the Peninsular War of the Napoleonic campaigns, the Battle of Salamanca, fought July 22, 1812, was a serious setback for the French, and a mighty setback for Salamanca, whose western quarter was seriously damaged. The battle which raged that day is famous as a defining moment in military history; many thousands of men were slaughtered by cannon fire in the space of only a few short hours.
