Tzars and Salesmen is a mod for Age of Empires II: The Conquerors, created by Ivacula.
Description (in authorís own words):
An alternative Expansion for the Age of Kings, requires the Conquerors for installation, but makes its own changes and de-activates the Conquerors campaigns. Appends the Balkan Tzardoms, Hungary and two Italian city-states to the list of playable factions. For now only random maps playable, but might feature a campaign in later updates.
Mod offers an installer.
