The Spanish language has a rich history which dates back to the Roman conquest of the Iberian peninsula. Latin was the official language of the mighty Roman empire and it would serve as the base language for Italian, French, Spanish, Portuguese and Romanian. To this day there are many remains of Roman ruins in Spain and many remnants of Roman culture. For example, the practice of bull fighting comes from the Romans and is still practiced to this day in Spain and parts of Mexico and France.
The Spanish language also has some Arabic influence considering that Moors from North Africa (a Muslim people) invaded Spain in the year 711 c.e. and were not expelled by the Christian kingdoms of Spain until 1492. During the Muslim occupation of Spain or Al-andalus as it was known under the Moors, Spain became one of worlds most sought after centers of intellectual engagement. Various sciences and pseudo-sciences were vigorously pursued during this period including; astrology, astronomy, alchemy, medicine and others. This period of occupation is known as one of the most productive scientific and scholarly periods in human history. As you can imagine there are many linguistical and cultural aspects that have been passed down from the Moorish Arabs to the Spaniards.
As we all know in the the year 1492 the Italian explorer Cristoforo Colombo or better known to us as Christopher Columbus was commissioned by the Spanish Monarchs Fernando e Isabella or Ferdinand and Isabella to go and search for a better route to India in search of spices and other luxury items. But as fate would have it he lost his way and ended up discovering the Caribbean islands of hispaniola (my parents native country) and Cuba among others. After Columbus many other conquistadores would force their way into Mexico and the rest of the Americas (Central and South America) and this is how the Spanish language arrived on the new world.
