Let $X$ and $Y$ be one-dimensional Peano continua. If the fundamental groups of $X$ and $Y$ are isomorphic, then $X$ and $Y$ are homotopy equivalent. Every homomorphism from the fundamental group of $X$ to that of $Y$ is a composition of a homomorphism induced from a continuous map and a base point change isomorphism.
