Every civilization has territory (areas of the map claimed as national land). The extent of your territory is the sum of all terrain squares under the cultural influence of your cities, which in turn is a result of the cultural value of each city. Borders Your territory is defined by your borders, which are drawn in your civilization's color, and clearly mark your cultural boundaries. The area within your borders is friendly territory. Advantages of Friendly Territory Your territory has several characteristics beneficial to you. * Rival civilizations cannot benefit from the roads or rails within your territory without a right of passage agreement. * You can always "see" squares in friendly territory. * Tradable resources are easier to get when found within your territory (no need for a colony). * You can eject rival military units from your territory during diplomatic negotiations.
