In the 19th century, "conservative" and "liberal" were first coming into vogue as terms for political viewpoints. What "conservative" and "liberal" meant then was different from what those terms mean in politics today. 19th century conservatives wanted to conserve and preserve the historic traditions of government and society. For societies like France and elsewhere on the continent of Europe, that meant going back to monarchs in control of government, as things had been before the French Revolution. Liberals were those who favored liberty for individuals, with greater rights and freedoms. So the various answers that spoke of voting rights, elected parliaments, and democratic change -- those all were measures favored by liberals in the 19th century, not conservatives.
"The U.S. Supreme Court case Marbury v. Madison (1803) established the principle of judicial review—the power of the federal courts to declare legislative and executive acts unconstitutional. The unanimous opinion was written by Chief Justice John Marshall."- loc.gov (Library of Congress)
