Representing the 21st Congressional District, he served four consecutive terms in Congress from January 3, 1935, to January 3, 1943. His tenure placed him among the historical members of Congress who participated in national legislative affairs during the late interwar and early World War II era.

Serving as a Representative for Texas, South was part of the Democratic Party’s delegation during a period marked by significant federal activity and change. Although specific committee assignments, legislative initiatives, and office contact details are not recorded in the available metadata, his eight years in office indicate sustained electoral support in Texas’s 21st District. Charles Lacy South left Congress as a former member after his term ended in 1943.
