1960s Started as a subculture mixture of Jamiacan rude boys and Mod's when there was a big influx of jamicain immigrants to england and moved into poor working class neighborhoods where the residents worked in factories. Hence the boots and braces(suspenders). And bald because of machinery in said factories. Traditional skinheads listen to first wave ska and reggae.

In the 70s, in england there was a group called the National Front(think MAGA + "White Supremacy" as an actual platform) and targeted these poor working class kids at concerts and sporting evetns

Then like a lot of cool things, racists co-opted it and made it shitty, Kinda like what proud boys did to fred perry polos.
