McHenry was a signer of the United States Constitution from Maryland and the eponym of Fort McHenry. He was a delegate to the Continental Congress from Maryland, and the third United States Secretary of War (1796–1800), under the first and second presidents, George Washington (administration: 1789–1797) and John Adams (administration: 1797–1801).

There are several ways in which we could justify this statement, but also many ways in which we would be able to challenge it.
In terms of support, we can argue that this was the case because the cultures of America did not have any significant contact with the cultures of Africa or Oceania until the arrival of the Europeans. We can also support this by the fact that the Andean cultures and the Mesoamerican cultures had no contact with each other.
However, there are several factors that show that this was not the case, or that the claim might be exaggerated. For example, we know that many groups in Africa had extensive interactions with each other. For example, the expansion of the Bantu that took place over large regions in Africa. Another challenge could be the extensive contact that many Mesoamerican groups had with each other.
