Julian is called "The Apostate" because he reverted from Christianity to Paganism, and wished to roll back Constantine I's imposition of Christianity as the state religion of the Empire.
He died in battle, and there were rumors at the time that he was shot by one of his own soldiers, a Christian who resented his beliefs. However, there was never any proof and it is now doubted.
Julian is an alpine town in [San Diego County]?, California renowned for its [apple pie]?.
