In the Europe of 1800's, the beliefs displayed in this question could be labeled as follows:
Conservative: The government should be led by a monarch with legitimacy from God; the government should mantain stability through a social class system. The explanation is that, those who call themselfs conservatives do so because they are in favor to keep things the way they are, manteining the status quo; the type of government that ruled Europe in 1800 was the monarchy, and they believed that stability could be reached by a social class system, the royal family and the plebeians.
Liberal: People should be able to work their way up the social ladder; the government should emphasize citizens' rights as listed in a constitution. Liberals, in general, believe and praise freedom for all people, and often the government's intervention in society is questioned; some say that the government's role should be smaller, intervening only in crucial questions, like the assurance of rights, while others believe that the government should have a central power figure.
