What is the history of a democracy system? Is it a fair system?

The origin of democracy is from the Greeks. In Greece, people would vote to decide how the society should function. They did not have major structures of parliament, but had assemblies and everybody had a right to vote, and ideas were put forward to make decisions.

As for it being a fair or an unfair system, slaves and women were excluded from voting, though they made up approximately 70 % of the population. Thus, this voting system was a decision made by the minority of inhabitants as to how the society would function. This was the so-called democracy system.
