Have you given thought to how international law might shape your world? Even having notes on which nations subscribe to a body of international law standards can be a fun way to add depth to the political landscape.
Legal systems can be interesting (no really!) Americans and Britons are used to a common law, where legal precedents form the basis for future rulings, but there are other forms as well - the Roman system of civil law, and the Muslim system of Sharia law also exist.
In my setting, a fallen empire’s legal system formed the basis for a loose international treaty for the kingdoms that arose in its place - thus, the Pandect, a series of codes and standards to which today’s kingdoms and republics all either flout, follow, or attempt to follow in various ways.

Have you ever tried making your own legal code? You are hereby sentenced to share.
Thanks! Ive always tried to build with those threaded connections in mind! When I look at my histories, I build each area with six pillars:
As I build each individually, I can start to see how they connect and weave them together. Then I see how these pillars connect to their geographic neighbors, and the so on. Gets a fairly solid coordination for the global history.
