One of the provisions in Article I Section 9 is Clause 8, which prohibits the federal government from bestowing titles of nobility. They had enough of that in England.
Wiki- One of the first issues that the United States Senate dealt with was the title of president. Vice President John Adams called the senators’ attention to this pressing procedural matter. Most senators were averse to calling the president anything that resembled the titles of European monarchs, yet John Adams proceeded to recommend the title: “His Highness, the President of the United States, and Protector of their Liberties,” an attempt to imitate the titles of the British monarch: “By the Grace of God, of Great Britain, France and Ireland, King, Defender of the Faith, Prince-Elector of Hannover, Duke of Brunswick” and the French monarch: “By the Grace of God, Most Christian King of France and Navarre.” Some senators favored “His Elective Majesty” or “His Excellency” (the latter of which would become the standard form of address for elected presidents of later republics). James Madison, a member of the House of Representatives, would have none of it. He declared that the pretentious European titles were ill-suited for the “genius of the people” and “the nature of our Government.”
