Marcian reversed many of the actions of TheodosiusII in the Eastern Roman Empire's relationship with the Huns under Attila and in religious matters. Marcian almost immediately revoked all treaties with Attila, ending all subsidy payments to him. In 452, while Attila was raiding Roman Italy, then a part of the Western Roman Empire, Marcian launched expeditions across the Danube into the Great Hungarian Plain, defeating the Huns in their own heartland. This action, accompanied by the famine and plague that broke out in northern Italy, allowed the Western Roman Empire to bribe Attila into retreating from the Italian peninsula.
