The original inhabitants of the Largo area were the Amerindian Tocobaga. Also known as the "Safety Harbor" culture as its archeological presence remains close to the current Safety Harbor. The Spaniards arrived in Florida in the 16th century. In the eighteenth century, the Tocobaga had virtually disappeared, after years of exposure to European diseases, Spanish colonization efforts, and the Spanish-British war. Largo's area, like the rest of Pinellas County, was largely abandoned. In 1763, England snatched Florida from Spain. In 1783, Spain got it back, but was forced to cede the region to the United States in 1821, following Andrew Jackson's invasion. In 1845, a surveyor observed Lake Tolulu, apparently located south of the bay and a more inaccessible place where Largo Central Park Nature Preserve is currently located. Among the first Anglo-Saxon inhabitants of the Largo area were the families of James and Daniel McMullen around 1852.

McMullens and other cattle-breeding settlers, cultivated citrus and vegetables, and were also fishermen. During the American Civil War, many residents of the area fought for the Confederate States of America. James and Daniel McMullen were members of the "Cow Cavalry" ("cow cavalry") that was driving Florida's cattle to Georgia and the Carolines to help sustain the war effort. Other residents of the area served on the ships breaking the blockade. Others also left the area to go on duty in the armies of the Confederates. After the war, the residents of the Largo area once again cultivated, managed their ranches and managed fishing. The "Orange Blossom Railroad" reached the area in 1888. Tolulu Lake was then renamed "Lake Largo", and residents of the community west of the lake adopted the well-known name "Largo".

The city of the Largo was incorporated in 1905. The long lake was drained in 1916 to increase land for growth and development. Between 1910 and 1930, the population of Largo grew by about 500%. Then and for decades afterwards, Largo's economy was based on citrus-growing agriculture, cattle ranches, and pig farms, as well as stumentine alambiques and sawmills. Largo is best remembered as the "Citrus City" of this period was the height of the packaging of citrus fruits, preserves and transport to the center.

The Great Depression cruelly manifested itself in the Long. Long lacked the financial resources to meet his requirements. Long returned to its status and limits in 1913. The population fell by about 30%. Debt incurred by bond issuance in the late 1920s was not paid until after World War II.
