The Tennis Court Oath kick-started the French Revolution. It was literally an oath sworn in a tennis court. Due to the dominance the nobility/clergy had over the Third Estate, The Third Estate established the National Assembly on June 17, 1789. Three days later, on the 20th, the National Assembly was locked out of their usual meeting place. So, they congregated to a near by tennis court on Versailles street. I find this event significant because The Third Estate was willing to take up the responsibility of having a say in the government in order to recieve the rights they deserve.
