The Battle of Ohio kicked off in 1970 when the Bengals joined the AFC Central Division, along with Cleveland, Pittsburgh and the Houston Oilers.
The first Bengals-Browns regular season game in Cincinnati on Nov. 15, 1970 drew the first home crowd of 60,000 in Bengals history (60,007 at Riverfront Stadium).
Virgil Carter threw a touchdown pass and scrambled for 110 yards on nine carries. Paul Robinson's one yard plunge sealed the win for the home team, giving head coach Paul Brown his first win over Cleveland with a 14-10 victory.
In just its third year of existence, the 1970 Bengals reached the playoffs, becoming the youngest franchise at that time to play in the postseason and Brown won the Associated Press NFL Coach of the Year award.
