Lesson 3: A Growing Sense of Nationhood

Key Idea

After the War of 1812, a wave of pride swept across the United States. Americans began to see themselves as one nation, not just as citizens of separate states. This powerful feeling of loyalty to the entire country is known as nationalism.

This new sense of unity helped quiet political fighting. The period during President James Monroe's term became known as the "Era of Good Feelings." Americans were now more willing to support the federal government and its plans to strengthen the nation as a whole.

Key Idea

After the War of 1812, leaders wanted the United States to become economically strong and self-sufficient. Congressman Henry Clay championed a plan to achieve this goal called the American System, which aimed to build a thriving national economy from the inside out.

The plan had three key parts: a national bank to provide a stable currency, a protective tariff (tax) to help American factories, and federal spending on internal improvements. These projects, like new roads and canals, would connect the different regions of the country.

Key Idea

While politicians worked to unify the country, the Supreme Court also played a key role. Led by Chief Justice John Marshall, the court made several landmark decisions that would define the power of the national government for generations to come.

Between 1819 and 1824, the Marshall Court heard cases that pitted federal authority against state authority. In these decisions, the court consistently ruled in favor of the federal government. These rulings established that the Constitution granted broad powers to the national government, ensuring its authority over the states.

Key Idea

As the country grew, questions arose about who had more power: the states or the national government? The Supreme Court, led by Chief Justice John Marshall, provided answers that strengthened the nation.

In one major case, the Court ruled that a state could not tax the national bank. In another, it decided that only the federal government could control interstate commerce—business that crosses state lines. These decisions established that the federal government had power over the states in certain matters, helping to unite the country under one authority.
