The expansion added to the base game new functions such as religion, espionage, three new scenarios, an expanded tech tree, several new entities, new religious and commercial city-states, nine new wonders and nine new playable civilizations: Austria (led by Maria Theresia), Byzantium (led by Theodora), Carthage (led by Dido), the Celts (led by Boudica), and Ethiopia (led by Haile Selassie), the Huns (led by Attila), the Maya (led by Pacal), the Netherlands (led by William) and Sweden (led by Gustav Adolf).  In addition, Spain (led by Isabella), which until now was only available as DLC in Civilization V, is included in the expansion.  There are 18 playable civilizations in the standard detail version of Civilization V.
7 DLC civilizations and 18 more were added by the two expansions, resulting in a total of 43 civilizations. The player chooses a civilization and assumes the role of its leader, based on leading historical figures like Napoleon Bonaparte.

The player can interact with the leaders of other civilizations via the diplomatic screen which he can access by clicking on a city of that civilization or on the diplomatic button at the top of the screen….
