Conservative regimes set up in 1815 were autocratic. They did not tolerate criticism and dissent and sought to curb activities that questioned the legitimacy of autocratic governments. Most of them imposed censorship laws to control what was said in newspapers, books, plays and songs and reflected the ideas of liberty and freedom associated with the French Revolution. The memory of the French Revolution nonetheless, continued to inspire liberals. One of the major issues taken up by the liberal nationalists, who criticised the new conservative order, was freedom of the press.
