Could something resembling this, with legal class divisions, restricted franchise, high concentration of wealth, internationalist-mercantilist tradition, and a military-economic-religious-political complex have developed from Cromwell's government? Like, if the monarchy was never restored?
In the alternate ideologies thread, I proposed something similar as an alternate path between the enlightenment and romanticism called martialism. To copy/paste my own work:
he ideology below is one that, if I ever had the time, I would love to make into it’s own thing, but it essentially exists as a “third way” between Romanticism and the Enlightenment. Just to be clear, below isn’t my views on the military (I am a pacifist), but a generalisation of a trend counter to the other two dominant movements.

Martialism
This ideology starts in an AH Cromwellian England where the Major Generals are more popular. Over time, a distinct ideological trend in the Anglo sphere comes into dominance, which essentially rationalises the military as the ideal over the state, nation etc. This isn’t in the same sense as militarism say, for Prussia (which was a distinctly romantic militarism), or for Bolivarian regimes (which was a distinctly enlightenment militarism), nor is it the belief in military rule as a temporary state of order.
Martialism views the nation state and the kingdom (in most cases) as a political fiction, believing that political power is only meaningful in relation to the ability to enforce it and that it is a military which solely defines and/or uplifts a person in meaningful terms and thus is the most important arbiter for rights. Citizenship is most deserving for those who enable the rights of citizens (the military), Conscription is seen as empowering and a martial lifestyle is the most virtuous because of it being the only one where an individual acts to uphold morality in real terms.
in short, think Agrarianism but with an emphasis on power (as opposed to tradition or liberty) as the ideal and with the soldier in place of the farmer.
Forms of Martialism
Democratic: A democratic martialism could rely on something similar to that of Starship Troopers, or be akin to a Jeffersonian democracy. Voting isn’t about the structure of society, but is instead for the establishment of military judges/tribunals who represent the citizens wishes in a senatorial fashion.
Oligarchy: Everyone is a conscript in some fashion, even if they work in the private sector (presuming there is a private sector) on the justification that mass conscription ensures responsible power to the citizenry who can rise to any heights

To be clear, the above isn't inherently intended to be an evil thing, and could also be described as "realism" in the political sphere to the extreme. Whilst seeing power as a virtue would naturally rub a lot of people the wrong way, the hypothetical martialist would find said sentiment absurd. "You can believe that God or a piece of paper grants you all rights you want, but it's because someone is wielding power that my wife and kids live safely in their homes".
