Really dude? the euro battles i've seen were kinda...small...i've seen usa based events with 50k people! every major city in the US has SCA (not that historical in some ways) and actual historical reenactment groups. Western and eastern sword play is very much studied from coast to coast in continental north america, armor smiths, weapon smiths, study groups who focus on the ancient arts over ancient battle techniques.
Tolkienism? with almost 400 million people the works of Tolkien are well alive, but have nothing to do with reenactment and armor when they are books.
