Final answer:
Constantine endorsed Christianity, broke from traditional Roman beliefs, and stabilized the economy.
Explanation:
Constantine broke from Roman tradition by endorsing Christianity and making it a state religion, which was a significant departure from the traditional Roman polytheistic beliefs.
This change was exemplified during the Battle of Milvian Bridge in 312, where Constantine prayed to Jesus Christ for victory, a departure from the customary Roman religious practices.
Additionally, Constantine eliminated the system of co-emperors and stabilized the economy by introducing a new currency, the solidus, based on a fixed gold standard.
