Why Is Spanish History Important

Spanish history. First thorugh fifth century?
Hello, I would ask if anyone can tell me the important events in Spanish history through the first of the fifth century. I could not find anything online, plus they were invaded in 407 A, C. And please if you can write the next century milestones for me to know what happened century. I have to do a little research of Spanish history from the 10th Century 1. Found information from the 5th century, but could not find anything earlier. Thanks
I take it you mean first to fifth century AD … The Iberian Peninsula (Spain and Portugal) was in the Roman province of Spania. Future Emperor Trajan was born there (conquered Dacia). Fifth Century: The Vandals, Swabians, and Alans established kingdoms there (The Vandals moved through Iberia on its way to North Africa). The Visigoths arrive and ends in mid-fifth century. (Both Vandals and Visigoths sacked Rome) I think Belisarius won for the Eastern Roman Empire, near the end of the century.
