Otto was the first king of Greece and ruled from 1832 to 1862. He had become highly unpopular with the Greeks for several reasons, such as his autocracy, his staunch religious beliefs, and his tendency to please the 'Great Powers' (Russia, the United Kingdom, and France). Even though the state flourished under him in some areas such as infrastructure, his reign was mostly controversial. He imposed heavy taxes and staunch Roman Catholicism on Greeks, which tarnished his reputation to a great extent. Moreover, the queen's unnecessary interference in the political affairs and her influence on Otto added to the public sentiments against him. However, Otto finally gave in to the heavy demands of the Greeks and declared the establishment of the constitution and the formation of a ‘Greek National Assembly.’ In his later reign, he lost the support of the 'Great Powers' and was forced into exile.
