The Battle of Arcadiopolis, fought in 1200 AD, was the turning point in Russian history that put a stop to any future Greek attempt to expand into Northern Europe. A Byzantine army had been proceeding through Bulgaria toward Russia (With the ultimate goal of conquering Kiev) when it was met by the Rus'. The numerically inferior Russian army, feigning retreat, drew off a large Greek contingent into a prepared ambush, routing it. After the rout of this detachment, the remainder of the Byzantine army also panicked and suffered heavy casualties from the pursuing Rus.
