Discover the essence of American history with our premium Union Flags at US Patriot Flags. Immerse yourself in the legacy of the Civil War, proudly showcasing the flags of the Union Army — the Federal forces affectionately known as the “Damn Yankees” or Northern Invaders. These symbolic banners flew under the command of President Abraham Lincoln, who famously sought to enlist Robert E. Lee at the war’s outset.
Our collection features authentic Civil War Union Regimental flags and star-pattern national colors that represented the United States during one of its most tumultuous eras. Unity was not guaranteed — but the nation’s resolve shone through.
The Evolution of the Union Flag During the Civil War
The United States of America flew four different official flags between 1861 and 1865 as new states joined the Union:
- 33-Star Union Flag — The flag flying at Fort Sumter when the first shots were fired in April 1861 (Oregon admitted 1859).
- 34-Star Union Flag — Official from July 4, 1861, honoring Kansas statehood. Most Popular
- 35-Star Union Flag — Added in 1863 after Unionist Virginians formed West Virginia.
- 36-Star Union Flag — Introduced in 1865 with Nevada’s admission.
Dive into the stories behind each flag. Every design — linear or circular star patterns — carries deep historical meaning. From the Fort Sumter flag that sparked the conflict to popular Custer-associated battle flags, these symbols embody sacrifice, perseverance, and ultimate victory for the Union.
All our Civil War Union flags are proudly Made in America with superior craftsmanship for lasting quality and vibrant color.
