In my quest to find out which martial art could be considered the closest to American, I discovered that it's none other than Catch Wrestling. Originally developed in the late 19th century, this combat sport combines elements of grappling and submission holds, reflecting the nation's influence from various immigrant cultures. It was popularized in carnivals and shows, proving its authenticity as an American martial art. So, if you're looking for a martial art with deep American roots, Catch Wrestling could be your perfect match. Its blend of various techniques truly embodies the melting pot philosophy of America.
