Smith has to be one. He's literally the father of capitalism, and viewed it as revolutionary against the existing feudal order.
The fact that the European empires later weaponized it as colonial enforcement and industrialization came along shortly afterwards to finish off what he viewed as a way for guildsman to control their own destinies is a tragedy beyond his control.
Probably it would end with like Bernie or some libshit like that, beside him is probably some European libshit like Macron, then like three older presidents of maybe Sweden or something
as much as I love Robespierre as a historical figure in the 'doing the shit that needs to be done' department, the guy was very anti left. the blooming beginings of French socialism and feminism had begun, and he absolutely tried to stamp those out
I think the lib pantheon is a little more crowded because their leaders are more often notable for either intellectual or political work rather than both, the way Lenin onward are. Early liberal revolutionaries didn't tend to write theory as significant or famous as that of their Enlightenment philosopher contemporaries, especially in Europe. Who in the modern day is reading Robespierre or Cromwell the way they would Smith or Ricardo? The United States had more crossover in fields though
Intellectually the 5 are probably John Locke, Adam Smith, Montesquieu, Rousseau, snd Voltaire. Maybe swap in James Madison, David Ricardo, or de Tocqueville for one of them.
For political leaders and revolutionaries, Oliver Cromwell, George Washington, Maximilien Robespierre, Simon Bolivar, Giuseppe Garibaldi.
My idealistic guess would be the philosophical split between rationalism and empiricism, which is a lot less pronounced in Marxism. See: Where Do Correct Ideas Come From?
I don't know what material factors would influence this division
he is undeniably the only leader to institute a formal codified constitution in Britain after the violent deposition of the monarchy, and his actions cemented the eventualities of the sovreignity of parliament. Washinton owned slaves, most French revolutionaries did not think too highly of the Haitian revolution, and Cromwell brutalised a rebelling Ireland. liberals do not see the contradiction in their ideals of maintaining the colonial order along side the claim all men are equal and free
