Summary: This paper contains a proof of the Jordan Curve Theorem based on the trivial result that \(K_{3,3}\) is non-planar. It then shows that the Jordan-Schönflies Theorem forms a bridge between the Jordan Curve Theorem and the classification of compact surfaces, and presents a new graph-theoretic proof of the Jordan-Schönflies Theorem.
