In this I would recommend “The Many Headed Hydra” as to the ground-up analysis of working class discontent going into the American War of Independence (really it talks about the development of the working class of the Atlantic Basin from the 1600s to the late 1700s, but the end cap there is the Age of Revolutions). I read it some years ago, but as I recall, the urban poor that made up part of the revolutionary armies were marshalled into service by the local bourgeoisie and slaver aristocrats after simmering discontent against Imperial authority had been building for centuries of indentured service, press ganging, work houses, enclosure of the commons, and other things I’m forgetting rn. The yoeman farmers who took up the patriot cause had their own materialistic reasons for revolting (namely, cheap land they could steal from the natives), as did the Loyalist farmers (tired of getting raided by aforementioned natives).

So, like, rebellion had been happening intermittently for a long time, it just took some young, plucky, genocidal fuckers to channel that working class anger into a focused attack on the British Crown.
