whats weird about american civil war reanctments is they are also done in canada , uk , australia , sweden and even poland 
Where are they done in the US?
the original reanactment is done near manassas battlefield
Oh that's cool, when did reenactments start happening?
it is believed it began back in 1961 to 1965 civil war centennial commemorations 
Do they have like an organization that organizes them for people to attend?
i honestly dont know that information , the time magazine estimated there were more than 50,000 reenactors in the u.s. alone
