The “No Union with Slavery” flag is a historically grounded abolitionist banner associated with radical anti-slavery movements in the United States during the decades preceding the American Civil War. The design typically reinterprets the Flag of the United States by incorporating the explicit slogan “NO UNION WITH SLAVERY,” a phrase widely used by 19th-century abolitionists who rejected any political compromise with slaveholding states. Variants of such flags appeared in rallies, printed broadsides, and public demonstrations, often modifying the canton or star arrangement to symbolically exclude slave states or critique the legitimacy of the Union. The inclusion of the bald eagle and star field reinforces national imagery while simultaneously subverting it with a direct ideological message.

The slogan itself is closely linked to radical abolitionist figures such as William Lloyd Garrison and publications like The Anti-Slavery Bugle, which popularized the doctrine of disunionism - the belief that the United States Constitution was complicit in slavery and that moral opposition required separation from slaveholding states. Historically documented examples of similar flags were carried in abolitionist gatherings, including an 1856 demonstration by free Black activists in Ohio, underscoring their role as tools of protest and political messaging rather than official national symbols. Today, the flag is recognized as a representation of uncompromising abolitionist ideology and a visual artifact of the intense sectional conflict that defined antebellum America.
