Which era followed the War of 1812 and was marked by national unity and a single political party?

• A. Gilded Age
• B. Era of Good Feelings
• C. Jacksonian Era
• D. Progressive Era

Answer: (B)

After the War of 1812, the United States entered a period known as the Era of Good Feelings. This era is defined by a sense of national unity and political harmony, largely because the Federalist opposition faded and the Democratic-Republican Party dominated national politics. Under Monroe’s presidency, there was broad agreement and a focus on national growth and rebuilding, which contributed to a feeling of unity. While tensions did exist beneath the surface—over issues like tariffs, a national bank, and internal improvements—the overall atmosphere fit the idea of one major party ruling and a unified nation. That combination—national pride plus one-party dominance—best matches the description in the question.
