Road and Distance

Road and Distance (Page 1)
In Common Universalis, each province has a 'Distance To Capital' modifier that affects province monthly autonomy, and province far away from capital will have their autonomy increase rapidly. To neutralize this penalty, you should connect the province to capital either through land or sea. Neighboring land provinces can be connected to each other by road, while coastal provinces can be connected by dock. Each of these buildings reduce province distance, and when a route to capital is formed, your province gains 'Connected To Capital' modifier which provides monthly autonomy reduction.

You can also set a second capital by province edicts, which serves as an alternative destination for province connection and distance calculation.
