Civilization III: Conquests is the second and final expansion for the award-winning and best-selling computer game Civilization III. It was published in 2003.


(See detailed section below.)

This expansion added seven new civilizations to the epic game, and including the eight civilizations from Play the World this brings the total number of playable civilizations up to thirty-one (the maximum supported by the game). The new civilizations are Byzantines, Dutch, Hittites, Incans, Mayans, Portuguese and Sumerians. In addition to these playable civilizations, graphics and text for the Austrians led by Charles V are present in the editor so one can replace an existing civilization.


Two new special traits are added in this pack: Seafaring and Agricultural. The new civilizations take advantage of these new traits (e.g. the Sumerians are Scientific and Agricultural), and the old civilizations are changed to more appropriate ones (e.g. the English have been changed from Expansionist and Commercial to Seafaring and Commercial).

Governments, Wonders, Terrain, Resources[]

New governments, Feudalism and Fascism, have also been added to the game.

There are new Wonders of the World:

Four new bonus resources have been included, two of which provide food bonuses to previously unprofitable terrain. Oases can now be found in deserts, Tropical Fruit in jungles, Sugar on plains and hills, and Tobacco on grasslands and hills.

In addition, two new types of terrain have been added: marshes and volcanoes. Players cannot construct cities on marshes, and cannot improve volcanoes in any way. Like jungles and flood plains, cities that have at least 1 citizen working a marsh may succumb to disease. Volcanoes may periodically erupt, destroying all improvements and cities and killing any units in some or all adjacent squares.

The centerpiece of this expansion pack, however, was the inclusion of scenarios ("Conquests"), intended for multiplayer gaming. Unlike the main ("epic") game, these scenarios took much less time to play, and focused on a specific period in history. Scenarios included in this expansion were Mesopotamia, Rise of Rome, Fall of Rome, Middle Ages, Mesoamerica, Age of Discovery, Sengoku, Napoleonic Europe, and World War II in the Pacific.


Generally the reception of this expansion pack was much better than that of Play the World.


One year after Conquests was launched, the latest Civilization III stand-alone version, Civilization III Complete, was also released. This version included Civilization III, Play the World, and Conquests. This version also includes several patches.

Two years later, Civilization IV was also released.
