Must be ostrogoths.
Jokes aside - romans burned city few times,too,during their civil wars.One of reasons why popes go to France in 1309 was constant fighting in Rome.
Other was King of France wanting pet pope to crush Templars,becouse he was out of money .Year after stealing all jews property.He later steal from longobards,and still do not have money.
Even today the French are still not good with money.
