>>13118099The default state of the German tribes was as follows: Caesar wrote of the Germans that they wanted to put as much distance in between them and their neighbors as possible (autism), and this is his explanation for a repeated pattern of behavior where they would cross the Rhine and fuck everything up.
This would be repeated over and over again until the Western Roman empire was so weakened that it couldn't even field an army against Atilla as he was coming for the city. It even continued after, and the Germans started settling in previously Roman areas like Hispania.
I read that their settlement patterns were unlike the Hispano-Romans, and they preferred fortresses and castles to cities, where the Hispano-Romans continued to live. I even read in this same book (I don't remember the name, but it's a scholarly work I read in undergrad) that when the Umayyads came in they wanted to settle in the cities, and a lot of the time they even left the Visigothic fortresses alone.
From this I conclude that had the Germanic settlers been more interested in a complete conquest of Hispania as the Romans had done, where they weren't interested in just holding hilltop fortresses but building civilization in the cities, then they would have had a reason to make a more valiant resistance against the Umayyads, who wouldn't have been able to just walk through Spain as they did.
