Why did Washington take action to end to the conspiracy in Newburgh?

Washington took action to end the Newburgh Conspiracy primarily to preserve the integrity of the nascent republic and maintain civilian control over the military. He recognized that the growing unrest among the Continental Army officers, who were frustrated over unpaid wages and lack of support, posed a serious threat to the stability of the government. By addressing their grievances and appealing to their sense of honor and patriotism, Washington diffused the situation and reaffirmed the principles of democratic governance, ensuring the loyalty of the military to the newly formed nation rather than to individual leaders or factions.
