Answer:
The person who declared war on Britain, which would lead to the awakening of the national consciousness of Americans.
Step-by-step explanation:
James Madison is the person who declared war on Britain in 1812. In addition to looting American ships, the British also abducted sailors. The British also supported the Indians in their struggle against the American settlers, which was sufficient reason to declare war.
Madison did not best estimate the actual ratio of military forces, so the United States enters the war against a far superior enemy. Such a relationship of military forces will result in numerous defeats by US forces both on land and at sea.
The nineteenth century in Europe was characterized by the awakening of national consciousness. This was also the case in America because it was this war that contributed to the national maturation of Americans. And if not everyone disagreed about the war against Britain, eventually the Americans would go to war against a common enemy.
