The Four Color Theorem was first proposed by Francis Guthrie in 1852. While working on a map of counties in England, he conjectured that only four colors were needed to ensure that no two adjacent regions shared the same color. This idea later sparked significant mathematical investigation and was eventually proven in 1976 by Kenneth Appel and Wolfgang Haken using computer-assisted methods.
