Explain three teachings of Rousseau which laid the foundations of democracy?

Jean Jacques Rousseau, through the book Social Contract, tried to put forth some ideas. The three teachings of Rousseau which laid the foundations of democracy were:

• Such a form of government should be formed which should be based on a social contract between people and the representatives.

• Louis XVI wanted to increase the taxes to meet the expenses of the state. So to decide about the new taxes, the king called the meeting of the assembly of the estate general in a resplendent hall in Versailles. Each estate had the one vote, and the same practice was to be continued on 5 May 1789. But the third estate demanded that each member should have one vote. Even though this demand was clearly rejected by the Louis XVI, but Rousseau discussed this idea in his book Social Contract.

• No group in the society should get privileges by birth, but every person in the society should be acknowledged based on their merits.
