Anybody got good examples of people working on pre-1850 history where they& #39;ve developed a narrative/impacts from their research around influencing social policy, government, policing, regional growth, etc. other contemporary challenges?

Ask b/c I& #39;m trying to engage with this discourse that seems increasingly prominent in universities on why/how research matters and I& #39;ve always felt - even with a lot of thought - that working before 1850 (even 1945) makes doing work with this kind of impact more difficult?

And please don& #39;t send me links to History and Policy. I& #39;m aware of that, but I want more examples and a broader sense of what is possible. I& #39;m not saying I like this sort of discourse, but I also feel like engaging with it might become a necessity and I& #39;d like to be more prepared

And if engaging with it a bit more makes me feel more secure and less anxious about my research then, to be honest, I& #39;m willing to change to make that happen.
