Azizi, at the risk of telling you what you may already know, there is a large "re-enactors" group or rather groups out there. I stumbled upon a mass meeting of them once at a celebration of Richmond's 350th anniversary. There were several Civil War contingents, including a group of African Americans in Union Garb with a cannon who had driven down from Massachusetts. I didn't have any kind of authentic garb, so I could only join as a Confederate.

There were also groups who called themselves "Mountain Men" who were out of a slightly earlier era.

Back in Massachusetts there are many re-enactors of the Colonial/ Revolutionary period. I've seen redcoats marching in tight drill with regimental bagpipes.

I have not seen Native American re-enactors, but it would not surprise me.
