George Washington Lafayette Bickley (1823 – August 1867) was the founder of the Knights of the Golden Circle, a Civil War era secret society used to promote the interests of the Southern United States by preparing the way for annexation of a "golden circle" of territories in Mexico, Central America, and the Caribbean which would be included into the United States as southern or slave states. Bickley was arrested by the United States government and it was during this time he wrote a letter to Abraham Lincoln expressing his distastes with Lincoln's handling of the government.

The Knights of the Golden Circle (KGC) was a secret society in the mid-nineteenth-century United States.  The original objective of the KGC was to annex a "golden circle" of territories in Mexico, Central America, Confederate States of America, and the Caribbean as slave states, to be led by Maximilian I of Mexico. The Golden Circle (Spanish: "Círculo Dorado" ) was an unrealized 1850s proposal by the Knights of the Golden Circle to expand the number of slave states.  It envisioned the annexation of several areas—Mexico, Central America, northern South America, Cuba, and the rest of the Caribbean—into the United States in order to vastly increase the number of slave states (it was proposed that Mexico alone be divided into 25 new slave states) and thus the power of the slave holding Southern upper classes.  After the Dred Scott Decision (1857) increased anti-slavery agitation, it was advocated by the Knights of the Golden Circle that the Southern United States should secede in their own confederation and invade and annex the area of the golden circle to vastly expand the power of the South.
