Answer:
Tennis Court Oath
Explanation:
Assuming you are talking about the French Revolution your answer would be the tennis court oath. In June of 1879 all the members of the French Assembly stated that they would stick together until a new constitution was written for France (this was because they wanted France to be more democratic inspired by the success of the American Revolution.) This promulgation happened on a tennis or squash court which gives the name the tennis court oath. I hope this helped!
