Conservatives believed that established traditional institutions of state and society like the monarchy, the church, social hierarchies, property and the family should be preserved. Most conservatives did not propose a return to the society of pre-revolutionary days. They realised from the changes initiated by Napoleon. A modem army, efficient bureaucracy, a dynamic economy, the evolution of feudalism and serfdom could strengthen autocratic monarchies in Europe. In 1815, the conservative regimes in Europe were autocratic. They did not tolerate criticism, dissent and tried to curb activities that questioned legitimacy of autocratic governments.

The King’s Mission Once there was a king who thought that to be a successful ruler he must know the answer of three questions. The questions were What is the right time to begin something? Which people should he listen to? What is the most important thing for him to do? The Wise Men and their Solutions The king sent messengers in all directions to find people who could answer these questions. Many wise men came, but their answers were all different. For the first question some of them felt that the king should follow a timetable, while there were others who felt that it is not possible to decide the right time for doing something in advance. Similarly, for the second question, some wise men said that the king should follow his councillors while others thought it was the priest whom the king should listen to. Then there were those who felt that it was the doctor the king should obey while there were many in favour of soldiers. For the third question some wise men said science should be of highest priority for the king while others said religion.
