Official USCIS answers

Why this is the answer
The 1800s means the 19th century, from 1800 to 1899. The United States fought several wars in that period, including the Civil War. So any official answer from that list is correct.
💡 Memory tip: Remember: 1800s = 19th century, so look for wars between 1800 and 1899.
