Remember that you are using the term in a peculiarly American way that would make no sense to a nineteenth century British person. In fact modern Europeans find American liberals pretty middle of the road, but that is a digression. A lot changed over that century. At the start universal suffrage (male) was dangerously radical. By the end female suffrage was probably the equivalent. Socialism in the sense of state redistribution of wealth and universal provision of welfare and health care would have seemed outlandish to most of the political establishment for much of the period. It wasn't until the early twentieth century that there was a state pension and social insurance.

The nineteenth century saw the beginnings of the first organised movement for social reform. Following the publishing of "The Rights of Man" in 1791 there was a growth in discussion groups such as the Correspondent Societies and the open, frank sharing of ideas, and for the first time, the inclusion of the labouring poor in these debates. Mass education was wonderful for improving the standard of work your employees can undertake, but they are also far more able to rebel against you.

Skip forward to the early 1810s and you can see an attempted social rebellion about to occur under the leadership of the Mythical Ned Ludd. The luddites, protesting the lack of job and wage security and the death of the artisan, were followed by the events of the Spa Field Riots, The Peterloo Massacre (where a peaceful rally for suffrage and lowered food prices was aggressively and fatal broken up by the Manchester Yeomanry), Swing Riots against the poor agricultural wages and rights, and then the Chartist movement in the late 1830s.

If the first half of the 1800s was a violent reaction to a new, industrial economy, the latter years were the maturing face of social campaigning. You had greater calls for general suffrage, suffragist movement began to develop and expand, and with the publication of Capital, a new socialist movement was blossoming, albeit very slowly and reluctantly
