A New Spain and Different Spain
In 449 King Rechiar of the Suebi invades Tarraconensis. Though meant to be merely a passing raid, Rechiar manages to defeat most of the Roman defenses quite easily and succeeds in conquering most of the province. Emperor Valentinian III manages to get a Visigoth-Roman army together in Gaul and invades Tarraconensis, but making sure Aetius does not lead the force, promising the Visigoths land in return for their help. The Roman army easily marches through Tarraconensis and only a few skirmishes are fought, rumors even prevail amongst the troops that Rechiar has decided to live the province all together but once they reach Zaragosa, these rumors immediately prove false. For outside the city a ready Suebi army waited. The Roman-Visigoth army lead by the current Visigoth king, attacked the following day and met decisive defeat. For the Suebi utilizing a pincer movement managed to encircle the numerically superior army and crush it. The battle resulted in the loss of the Visigothic king and his 2 sons who came with him and the destruction of the army. It also paved the way for the Suebi conquest of the Spanish Mediterranean coastline a few months later. From then on Rechiar declared himself as Rechiar, Emperor of the Suebi and Hispania.
The Visigoths
After the loss of their King and his sons the Visigoth people fell into a civil war between various claimants to the throne. This allowed them to fall into Roman influence again and the Roman General Aetius even attacked the Visigoths after a marauding Visigoth army attaced the a Roman garrison in Gaul. Though it was just a small raid it strengthened the Roman position in Gaul and raised Aetius popularity in the Western Roman Empire
