Cool. Ernest Cœurderoy (also a self-identified anarchist) wrote about western european chauvinism, imperialism, colonialism & industrial expansion in the 1850s. https://twitter.com/anarchopac/status/1289946968408481793

"As long as there are proletarian men, there will be poor nations; & the same instrument of oppression, government, which preserves privileges between individuals, will preserve them between peoples... & extend to an entire continent the exploitation by the rich of the poor."

"No, it is not possible that entire regions, Italy, Savoy, Poland, Alsace, Hungary, Ireland, Algeria; colonies, remain, like torn shreds, included in empires which are unified with them only to devour their substance..."

Also there's the analysis in the Native Movement newsletter (& of others):
"Colonial expansion did not come about because of the need for markets for surplus production. On the contrary, surplus production came about as a result of colonial expansion." https://mgouldhawke.wordpress.com/2020/04/17/capitalism-the-final-stage-of-exploitation-1970/
