The Industrial Age is the fourth Age in Age of Empires III, following the Fortress Age. It is characterized by the Industrial Revolution which took place during the 18th and 19th centuries. The Industrial Revolution was a massive economic, social, and technological change facilitated by the introduction of steam power and the use of automated machinery in manufacturing.
