Tribune (from the Latin: tribunus spielautomaten spielen; Byzantine Greek form τριβούνος) was a title shared by 10 elected officials in the Roman Republic. Tribunes had the power to convene the Plebeian Council and to act as its president, which also gave them the right to propose legislation before it. Also, the tribune could summon the Senate and lay proposals before it. The tribune's power, however, was only in effect while he was within Rome. His ability to veto did not affect provincial governors, and his right to sacrosanctity and to help only extended to a mile outside the walls of Rome. In about 450 BC the number of tribunes was raised to ten.
