I would like to know what else I can use instead of 'disputed regions', I've used conflicted territories, but that doesn't sound right. Are there any other combinations of two words that have the same meaning as 'disputed regions'?
contested land(s) TFD
- To compete or strive for; struggle to gain or control: trade routes that were contested by competing cultures.
When the region is controlled by one party A, but it historically belonged to another party B, the region is called an irridenta. According to Collins Dictionary:
a region that is ethnically or historically tied to one country, but which is ruled by another
