Revolution

Revolution is a feature available in the Age of Empires III: The WarChiefs. It allows European civilizations to revolt from their home country and form a new political entity with additional unit types and specific bonuses, at the cost of being unable to advance into the Imperial Age.

Overview
Revolting is an alternative to the Imperial Age allowing a choice of one of two revolutionary leaders per civilization, each with different bonuses. Revolting costs and takes only 10 seconds, which is much cheaper and faster than advancing into the Imperial Age (which costs  and takes 90 seconds).

Only one player may revolt in a game; after someone revolts, all other players (including teammates) won't be able revolt themselves. However, if a player revolts, any other players can still advance to the Imperial Age.

Once Revolution is researched...
 * ...the player's Home City flag will change to the flag of the relevant new country, and their deck will also change to a Revolution Deck (see below)...
 * ...all Home City shipments on their way will be canceled...
 * ...all buildings that are being constructed (except by Wagons) will be left incomplete...
 * ...all Settlers (including Coureurs des Bois and Settler Wagons) will turn into Colonial Militia; Settlers that are being trained will be canceled with their Food costs refunded, and any Settlers or their equivalents rescued from Treasures will turn into Colonial Militia...
 * ...Town Center build limit is automatically increased to 10, regardless of the nation played...
 * ...and the player will be able to support all 200 population without Town Centers and Houses.

As Revolution is not counted as an Age, all units that are automatically upgraded in every Age (Explorer, Explorer's Dog from Home City shipment, Spahi, Spy, Petard, etc.) will not be upgraded when the player revolts.

Even though a revolting player no longer have Settlers to gather resources, they still can keep a small economy going through the following:
 * Trading Posts built by Explorers on trade routes
 * Fishing Boats
 * Banks
 * Factories
 * Resource trickle Home City cards (only if they are sent before revolting)
 * Cree Coureur des Bois

Simply put, revolting is an incredibly powerful boost to a civilization's military, but halts its economy.

Strategy

 * It is still possible for a revolting player to win by a trade monopoly.
 * The "move all military units to one location" button on the right hand corner of the mini map is very useful at the start of a Revolution and allows players to move all of their Colonial Militia to one point on the map.
 * Have Factories in game before initiating a revolution (if the Home City cards are available). This will help produce resources as all Settlers will become Colonial Militia. Trading Posts, especially upgraded to Stagecoach or Iron Horse, are also very useful.
 * Ensure that a few shipments are available when revolting. This will help to get a couple of Fort Wagons and a few Gatling Guns just in case. Or if one feels so and are in a hurry, send important shipments from the Home City before revolting, such as Factories and unit upgrades.
 * Ensure that a large stockpile of resources are available to build more units as skirmishers and artillery can easily kill Colonial Militia.
 * Ironclads are good with their special long distance shell, but also have some support ships to protect them in close quarter fights as they can only be sent by Revolutionary Deck cards.
 * After revolting, search for Cherokee and Cree native settlements, which gives the Sequoyah's Cherokee Syllabary improvement (which ships 4 Settlers) and trainable Coureur des Bois respectively, allowing the player to have some workers.
 * Ensure that all the important buildings (such as Artillery Foundry, Arsenal and Church) are built, since they can't be constructed anymore after revolting.

Revolution Deck
All of the listed Home City cards can be sent an INFINITE number of times.

Trivia

 * The revolution choices for certain civilizations (e.g. Germans can become Argentina or Peru and Ottomans can become Chile or Colombia) are not historically accurate for gameplay and balancing reasons.
