Imperial Age (Age of Empires II)

This article is about the Age in Age of Empires II. For other uses, see Imperial Age.

The Imperial Age is the fourth and final Age in Age of Empires II. It gives access to gunpowder units (except for the Aztecs, Huns, Incas, Cumans and Mayans) and heavy siege units.

Additionally, once the Imperial Age is reached, a Wonder can be built by any civilization. When playing a random map, Post-Imperial Age can be chosen as the Starting Age, which is the same as the Imperial Age, but with all technologies (available to each civilization) already researched.

The Imperial Age is preceded by the Castle Age.

History[]

“	The rise of great kings and their quest for empire brought about the final segment of the Middle Ages that can be called the Imperial Age. The feudal system was being replaced by kings at the head of nations in England, France, Spain, and Scandinavia. Trade was booming and cities were growing in size and power. The Renaissance was underway in Italy and spreading across Europe. Technology and learning surpassed that of the ancient world. Firearms and other innovations brought an end to the military dominance of knights and castles. This end of the Middle Ages can be marked by several important events, including the Turkish capture of Constantinople, the discovery of the New World, trading contact by sea with Asia, and Martin Luther’s Reformation.	”
