Requests for manga where political and wartime strategy is important to the plot.

So I've recently been reading Yona of the Dawn, and while it's not the best story I've ever read, I found myself thoroughly impressed with how well the political side of the story is handled.

Large scale military tactics, borders and international relations, strong vs. weak diplomatic choices, etc. are all massive focal points that the series does not shy away from having be a thing that genuinely affects the plot and the characters. Even something as simple asearly on in the series they use the concept of having a dam built for one village as a way to punish on another village for refusing to fully embrace the new king. That to me was such a well written concept as I would imagine that being exactly how a real country would place pressure on a region as opposed to sending in an army to massacre everyone like a lot of shonen would do.

As such; I'm interested to read more work that has this sort of idea, but I don't know where to even start looking. Any suggestions?
