The history of the Spanish language and the origin of Spanish dialects begins with the linguistic evolution of Vulgar Latin. The Spanish and Andalusian dialects appeared in the Iberian Peninsula (Hispania) in the Middle Ages. The emergence of modern Spanish more or less coincided with the reconquest of Muslim Spain, completed by Isabella of Castile and Ferdinand of Aragon. The Spanish language originated in the southwestern region of Europe, known as the Iberian Peninsula. Shortly before the end of the 6th century BC, the region's first inhabitants, the Iberians, began to mix with the Celts, a nomadic people originally from central Europe. The two groups formed a people called the Celtiberians, speaking a form of Celtic. Under Roman rule, in 19 BC, the region became known as Hispania and its inhabitants learned Latin from Roman merchants, settlers, administrators and soldiers. When the classical Latin of the Roman educated classes mixed with the pre-Roman languages ​​of the Iberians, Celts, and Carthaginians, a language called Vulgar Latin appeared. The basic patterns of Latin were followed, but words were borrowed and added from other languages. Even after the Visigoths, Germanic tribes of Eastern Europe, invaded Hispania in the 400s A.D., Latin remained the official language of government and culture until around 1940. the year 719, when Arabic-speaking Islamic groups from North Africa called Moors completed their conquest of the region. Arabic and a related dialect called Mozarabic became widely spoken in Islamic Spain, except in a few remote northern Christian kingdoms, such as Asturias, where it survived...... middle of paper ... .stas and liberals, who encouraged a certain literary renaissance of Galician, particularly of a political nature, with plays in verse and dialogues or speeches in prose, which today are of interest from the point of view of the history of the language and society of the region. However, the real renaissance did not occur until the mid-19th century, mainly through poetry. It became the co-official language of Galicia in 1981, but is also spoken in the regions of Asturias and Castilla-León. Today, almost two million people speak Galician, although, due to its similarity with Spanish and the multiple interferences derived from a practically universal bilingualism, it is very difficult to make an exact calculation. To this figure we must add the Galician communities that live in Latin American countries that use it..
