<span>One of the leading journals promoting the philosophy of the Era of Good Feelings was Niles Weekly Register, founded in 1811. Hezekiah Niles believed strongly in the American national purpose and his publication, supported entirely by subscriptions and carrying no advertising, was highly influential at the time. </span>
The War of 1812 was actually fought in multiple places including North America, the Pacific Ocean, the Atlantic Ocean, the East Coast of the US, and the Gulf Coast of the US. Hope this helps!!
The disclosure of this document contributed to <span>the entry of the United States into World War I, since Germany had been sinking US ships that were holding supplies. </span>
