History

The site of Hannibal was originally inhabited by various cultures of indigenous Native American tribes.

The river community is best known as the mid-19th-century boyhood home of author Samuel Langhorne Clemens (aka Mark Twain, 1835-1910). Twain drew from his childhood settings for his novels The Adventures of Tom Sawyer (1876) and Adventures of Huckleberry Finn (1884). Numerous historical sites are associated with Mark Twain and the places depicted in his fiction.

Heritage tourism contributes to the Hannibal economy, as the city attracts both American and international tourists. The Mark Twain Boyhood Home & Museum marked its 100th anniversary in 2012; it has had visitors from all 50 states and some 60 countries. Most Hannibal residents enjoy the visitors, and the town at large benefits from tourism revenue.

Background

After the United States acquired the Louisiana Territory west of the Mississippi in 1803, European-American settlers began to enter the area. Its early European settlements were established by ethnic French colonists, some from Illinois, who largely spoke French and were Roman Catholic in religion.

Hannibal was laid out in 1819 by Moses Bates and named after Hannibal Creek (now known as Bear Creek). The name is derived from Hannibal, a hero of ancient Carthage (now in Tunisia).

The city grew slowly, with a population of 30 by 1830. But by 1846, Hannibal was Missouri’s third-largest city when the Hannibal and St. Joseph Railroad was organized by John M. Clemens (Mark Twain’s father) and associates. This railway was built to connect to St. Joseph, Missouri in the west, then the state’s second-largest city. This railroad was the westernmost line before the Transcontinental Railroad was constructed. It transported mail for delivery to the first outpost of the Pony Express.

Construction of railroads to the area and increased steamboats on the Mississippi River had stimulated growth. In 1843 the city had also annexed the town of South Hannibal. Hannibal gained “city” status by 1845. By 1850 it had 2,020 residents.

In the late 19th and early 20th centuries, the city has served as a regional marketing center for livestock and grain, as well as other products produced locally, such as cement and shoes. Cement for the Empire State Building (completed 1931) and Panama Canal was manufactured at the Atlas Portland Cement Company in the nearby unincorporated company town of Ilasco.

The Mark Twain Memorial Lighthouse was constructed in 1933 as a public works project under President Franklin D. Roosevelt. It has been lit on ceremonial occasions at three separate times by Presidents Roosevelt, John F. Kennedy, and Bill Clinton. Rockcliffe Mansion, a private house on a knoll in Hannibal, is listed on the National Register of Historic Places.

In 2011, the Mark Twain Boyhood Home and Museum released Mark Twain: Words & Music, a CD featuring entertainers who recount Mark Twain’s life in spoken word and song. Several songs were written especially for the project and refer to Hannibal, including “Huck Finn Blues” by Brad Paisley and “Run Mississippi” by Rhonda Vincent. Other artists include Jimmy Buffett as Huckleberry Finn, Clint Eastwood as Twain, and Garrison Keillor as the narrator of the project.
