Catherine the Great ruled Russia from 1762 to 1796. She tried to modernize Russia in many different ways, ranging from economic reforms to governmental and even social reforms. Her reforms were not particularly effective, however, and Russia continued to be less modern than other European countries.
For example, Catherine tried to modernize the Russian economy by breaking down state monopolies over various areas of the economy. She modernized government by setting up different levels of government (like provinces and districts) so that the governing of the country could be more efficient. She even experimented with allowing greater freedom of speech.
