What is the difference between excommunication and interdict?

The difference between excommunication and interdict is that excommunication is when she or he is cut off from the church and he or she would not receive any of the sacraments nor be buried on holy ground while interdict is when rulers rebel against the church, the church would then issue an interdict ( all the churches in that region would be closed and everyone who lived there would be in danger of eternal condemnation).
