Politics is often an important aspect in most timelines. However, this list of timelines only includes those where politics and politicians of a specific era and country (or set of countries) play a leading role in the timeline's narrative and are featured frequently. Timelines where politics are more in the background of the narrative should not be put into this list.
For instance, timelines about alternate political careers of OTL politicians (or people who briefly entered politics in OTL) can go on this list. In contrast, timelines where one country fights with the other, but their governments and governmental figures are rarely (if ever) seen in person, should not be included on the list.
