After the developments of the 1930’s -once surpassed the Great Depression, having launched the Second New Deal and the Wagner Act and The Social Security Act of 1935- liberal democracies started to differentiate from authoritarian governments in many forms.
In Authoritarian governments, just one ruler with the support of a small group of leaders has the power. Citizens do not have free choice and have no opinion in the government decisions. We find this type of government in North Korea or Cuba.
Meanwhile, in liberal Democracies, the citizens are actively participating in politics, have freedom of speech, action and can choose its religion. In a true Democracy, human rights are respected and the Media is not controlled by the government and the rulers are elected by elections. In a Democracy, the government is in contact with the people and listens to their demands.
Nowadays we find liberal democracies in France, England, the United States, and Canada.
