What are some differences between democracy and dictatorship?
There are no governments on earth that are pure democracies. In such a government every single person would share authority and responsibility for government, and everyone would vote on everything. It is easy to see that government would come to a standstill in any nation of more than a few dozen people.
.
Nations that have a democratic element are those where the people have a substantial say, through a system of voting, who is representing them in the government, and where leaders are not governing for life, or because they are strong enough not to be removed from office. There are many nations that have a multi-tiered level of representation, and this is a broadly appealing and usually effective kind of government. The UK, for example, have the general voting population and the House of Commons. There is the House of Lords, and then the reigning monarch. The US Congress along with the president can be seen as roughly analogous. In a democracy representatives that govern the people are voted in by the people through free and fair elections with multiple parties. A dictatorship has one authoritarian leader who was probably not elected and probably does not rule in the best interest of the people.
