The city was founded in 1853. At the time of its incorporation in 1858, the city had a population of about 1,950. African-American man, Jordan Jameson was lynched on November 11, 1919, in the town square of Magnolia. A large white mob seized Jameson after he allegedly shot the local sheriff. They tied him to a stake and burned him alive. The city grew slowly as an agricultural and regional cotton market until the discovery of oil just east of the city in March 1938, with the Barnett #1 drilled by the Kerr-Lynn Company. The Magnolia Oil Field was an important discovery for the city as well as for the nation, as it was the largest producing field (in volume) during the early years of World War II, helping to sustain the American war effort.
