Liberals. They opposed the uncontrolled power of dynastic rulers. They wanted to safeguard the rights of individuals again* governments. They argued for a representative, elected parliamentary government, subject to laws interpreted by a well trained judiciary that was independent of rulers and officials. However, they did not believe in universal adult franchise. They felt men of property mainly should have the vote.
Radicals. Unlike liberals, they opposed the privileges of great landowners and wealthy factory owners. They were not against the existence of private property but disliked concentration of property in the hands of a few.
Conservatives. Earlier, in the eighteenth century, conservatives had been generally opposed to the idea of change. By the nineteenth century, they accepted that some change was inevitable but believed that past had to be respected and change had to be brought about through a slow process.
