a united country that displayed a great amount of nationalism is characteristic of which era?

A united country that displayed a great amount of nationalism is characteristic of the Jacksonian Era (also called the Age of Jackson) in U.S. history.

What the question is asking

The wording matches a common multiple‑choice/quiz question in U.S. history about nationalism after the War of 1812.

In that context, the correct era is:

• The Jacksonian Era (roughly the 1820s–1830s), when:
  • Many Americans felt a growing sense of national unity.
  • Politics increasingly emphasized the “common man” and national identity over narrow regional elites.

Why the Jacksonian Era fits

• The period after the War of 1812 is often described as an age of rising nationalism , with Americans seeing themselves more as members of one nation than separate states.

• In school materials and homework help sites, the specific phrasing “a united country that displayed a great amount of nationalism is characteristic of what era?” is answered as “The Jacksonian Era.”

Answer: The Jacksonian Era.
