I apologize for the confusion again. In order to accurately answer the question, it would be helpful to have more context or information. The transition of Rome from a monarchy to a republic involved various factors and groups. While the commoners did play a role in the eventual establishment of the republic, it was not solely their effort. Other influential groups like patricians, or aristocrats, also contributed to the overthrow of the king and the formation of the Roman Republic. Therefore, the correct answer could be either "commoners" or "aristocrats."
Rome became a republic after the citizens overthrew the king.
