About succession and countries

When you are adding labels to #Wikidata the infoboxes are the main inspiration and source of information. To the right you find a detail of the infobox of the Almohad caliphate. It shows really interesting information.

When you look at the size of the Almoravid dynasty, you will agree that the Almohads have absorbed other countries as well. In a similar way, the succeeding countries are unlikely to have killed of the Almohads all at the same time. It also becomes obvious that there is little relation to the countries that exist in the territories of these past domains

There are multiple ways to bring some clarity in all this. One is to show overlaying maps and the other is to use qualifiers with the data. The succession is likely to have coincided with events, events like battles. These events have dates and coordinates. These events link back to the countries that are in conflict.

To get such data in a consistent manner in Wikidata will take a lot of effort. I am curious if there are sources that already found their way to express it effectively. I am a fan of importing data but I am equally convinced that there is a lot where judgement and involvement is the only option.
