Chief executive of the Roman Republic?

The chief executive officers of the Roman Republic were the consuls and praetors. Two consuls were chosen annually and they administered the government and led the Roman army into battle. On 366 BC, a new office was created, that of the praetor. The praetor could govern Rome when the consuls were away from the city and could also lead armies. The praetor's primary function however was the execution of justice. He was in charge of the civil law as it applied to Roman citizens.
