This command starts the integration process of one country into another. If the two specified countries are already integrating, this command will instantly complete the integration process.
integrate [country tag] [country tag]
|Country Tag||The tag of the country you wish to integrate into another.|
|Country Tag||The tag of the country you wish to have the first specified country integrated into. If not specified, this will be the country you are currently playing as.|
The above command would start the integration process of France (FRA) into your current country. If the integration process has already started, this would complete it instantly.
integrate FRA ENG
This example is the same as the first, but as we have specified England (ENG) a second country tag, France would be integrated into England rather than the country you are currently playing as.
