History of Spain
The history of Spain dates back to the Early Middle Ages. In 1516, Habsburg Spain unified a number of disparate predecessor kingdoms; its modern form of a constitutional monarchy was introduced in 1813, and the current democratic constitution dates to 1978.
After the completion of the Reconquista, the kingdoms of Spain were united under Habsburg rule in 1516. At the same time, the Spanish Empire began to expand to the New World across the ocean, marking the beginning of the Golden Age of Spain, during which, from the early 1500s to the 1650s, Habsburg Spain was among the most powerful states in the world.
During this period, Spain was involved in all major European wars, including the Italian Wars, the Eighty Years’ War, the Thirty Years’ War, and the Franco-Spanish War. In the later 17th century, however, Spanish power began to decline, and after the death of the last Habsburg ruler, the War of the Spanish Succession ended with the relegation of Spain, now under Bourbon rule, to the status of a second-rate power with a reduced influence in European affairs. The so-called Bourbon Reforms attempted the renewal of state institutions, with some success, but as the century ended, instability set in with the French Revolution and the Peninsular War, so that Spain never regained its former strength.
Historical findings suggested that Spain was built about 30000 to 50000 B.C. The Iberian population arrived to the peninsula from the north of Africa. Tartessos founded an important kingdom of high culture in the Valley of Guadalquivir River, in the south of Spain. By 1200 B.C. Celtic tribes entered the peninsula from the north, mixing up with Iberians and so generating the Celt Iberian race.
Romans also invaded the colonies in Spain, and ended up conquering the entire peninsula after Rome had defeated Carthago. The province Hispania became part and parcel of Roman Empire and acquired great importance.
In 409, when the Roman Empire started to fall, Gothic tribes invaded and established their kingdom in 419.
