As political differences began to fade away, what phrase did a Boston newspaper use to describe the years after the War of 1812?

After the War of 1812, America' sense of social and political unity was at an all time high, especially after fending off the British for the second time in less than 50 years. To describe this period of American unity, a Boston newspaper described this time of the "Era of Good Feelings." This title represented both the unity in America's moral after defeating the British, but it also refers to the lack of arguing/fighting in politics. This era brought the collapse of the Federalist party, with only the Democratic-Republican party remaining. This party began to unit and settle several differences that divided them prior to the war. This era lasted less than a decade and would precede some of the most divisive eras in American history.
