I’m not sure on politics, however that time period is when society developed the middle class and started to have “rules” of society, like you aren’t supposed to wear this and don’t act this way, etc.
If you are talking about the Second Industrial Revolution, then the person who had a monopoly in the steel industry was Andrew Carnegie.
Hope this helps!
