A good recent book is The Dawn of Everything by David Graeber and David Wengrow. They describe a number of early societies that were organized without hierarchies, and argue that hierarchy is not necessary for organized societies today.
At first, I thought it was a pretty good video aimed at people unfamiliar with the ideas of anarchism. Then they said that Boogaloo Boys are anarchists, which is not at all accurate. Crash Course is misinforming their audience here, unfortunately.
Yeah, I immediately had my doubts when I saw it was Crash Course, and my instincts were right. They're good for learning things like basic history and government, but even there they've always had a strong pro-capitalist/pro-federalist bias. They're not reliable for anything remotely leftist or anarchist.
Boogaloo Boys are a far-right accelerationist organization/movement that are named after their desire to launch a second civil war in America (“Civil War 2: Electric Boogaloo”). They’re closer to being Proud Boys or Three Percenters than they are to reading Kropotkin or organizing with Food Not Bombs.
I would say this is similar to how “anarcho”-capitalists try to lay claim to anarchism while espousing right-wing ideas. They might try to claim the name, but their ideology is far from anarchist in actuality.
