Colonization is a new form of attack in the new Evony: Age II. In order to colonize someone you must be a Baronet.
Colonizing is when you make someone a vassal of yours, you get a percentage of everything they produce. They can at some point, rise up against you.
After you run an "Colonize" mission on a city, if you are successful in your attack you enter a "colonization period". From our experience this is roughly 5 hours. After the colonization period, if the player does not uprise against you, the city becomes your colony.
To perform actions on your colony, click on "City Overview" of the city you colonized with and click on "Valleys" and choose the "Colonies" tab. Click view on the colony you wish to perform an action on and you should see a bunch of buttons. They are as follows:
+ Tax Imposition
+ Food Levy
+ Pop. Redeployment
+ Sow Discord
+ Abandon: Abandons the colony.
When you click on a city (yours or another player's) you'll see a Suzerain now as well. If a city is colonized by someone the suzerain shows you who the colonizing lord is.
HOW TO BECOME UNCOLONIZED
When you are colonized you can start an uprising to become uncolonized. To do this, go to the city that has been colonized and click on your town hall. Under the valleys tab click on the "Uprising" button.
YOu may also go to the "Quests" button and go to "Commission Quest". From there you can issue an anti-colonization quest for other players to help you get rid of the offender. You have to post up a reward for this.
