Civilizations (commonly abbrieviated as Civs) are playable factions in Age of Empires Online. There are currently six available civilizations, three Pro and three Free-to-Play/Premium civs.
There were three classes of civilization. Free-to-Play and Premium civilizations started at level one (or level three if one skipped the tutorial levels) while Pro civilizations started at level twenty. Though Pro civilizations lacked a unique main campaign, they gained immediate access to Argos, Northern Hold, and Fertile Crescent (the latter two both DLC addons).
