A consul is a diplomat appointed to live in a foreign country, to protect both her country's interests and citizens living abroad. If you're an American living in Poland, take your troubles to the American consul. In ancient Rome, there were two consuls elected every year to be in charge of the whole city.

Rome knew four classes of people.
