The very first military setback for Adolph Hitler and his forces was the Battle of Britain. This occurred during WWII when Hitler was forced to cancel his planned invasion of Britain. This operation was known as Operation Sea Lion. He continued to bomb them but was unsuccessful in defeating them.
The answer is held the country together prior to the implementation of the constitution. I hope this helps. :)
The first 3 articles of the Constitution establish the 3 branches of government with specific powers. Executive (headed by the president), Legislative (Congress), and Judicial (Supreme Court)
Article 1 - created the Legislative branch
Article 2 - created the Executive branch
Article 3 - created the Judicial branch
