The election of 1816 marked the beginning of a new chapter in American history. After two terms, James Madison left office. Then, James Monroe became the fifth president. Monroe took office in 1817 at a time when many Americans were hopeful about the country's future. The War of 1812 had ended, the country was experiencing a growing sense of national pride, and political disagreements seemed less important than they had in the past. Historians named this time the Era of Good Feelings.

The Era of Good Feelings generally refers to the years of James Monroe's presidency, from 1817 to 1825. Many Americans felt the nation was growing stronger and more united during these years. The Federalist Party, one of the country's first political parties, had lost much of its influence after the War of 1812. As a result, the Democratic-Republican Party dominated national politics. With fewer political battles between major parties, many people believed the country had entered a time of greater cooperation.
Soon after taking office, Monroe traveled through the northern states on a goodwill tour. His goal was to encourage national unity and ease the political divisions that had grown during the war. Even in places where many people had once opposed his party, Monroe received a warm welcome. When he visited Boston in 1817, thousands of people attended parades, speeches, and celebrations in his honor. A newspaper called the Columbian Centinel described the optimistic mood by using the phrase "Era of Good Feelings." The name quickly became associated with Monroe's presidency and has been used by historians ever since.

The hopeful mood of the period was about more than politics. Many Americans believed their country was becoming stronger after successfully defending its independence during the War of 1812. Leaders in Congress looked for ways to support the nation's growth and strengthen its economy. In 1816, Congress created the Second Bank of the United States to provide a more stable financial system for the country. Lawmakers passed the Tariff of 1816. This made imported goods more costly. The goal was to encourage American manufacturing. Many leaders supported improving roads and transport. This would help people and goods move easily across the expanding nation. These efforts showed a growing belief that the United States should be more connected, self-sufficient, and economically strong.
James Monroe became a symbol of this hopeful period. Like many leaders of the early republic, he believed that political parties often divided the nation rather than bringing people together. Monroe wanted to promote cooperation during his presidency by working with leaders from different regions and political backgrounds. Many Americans disagreed on issues, but many felt the country was becoming more united. They also saw a rise in optimism and national pride. For these reasons, Monroe's presidency became known as the Era of Good Feelings.
