Harrison is named for US President William Henry Harrison. William Henry Harrison (February 9, 1773 - April 4, 1841) was an American military leader, politician, the ninth President of the United States, and the first President to die in office. The oldest President elected until Ronald Reagan in 1980, Harrison had served 30 days in office, still the shortest tenure in United States presidential history, before his death in April 1841. His death created a brief constitutional crisis, but ultimately resolved many questions about presidential succession left unanswered by the Constitution until passage of the 25th Amendment.

Harrison County was created on February 5, 1841 Hancock, Jackson and Perry Counties, with the following described limits:
"Beginning at the point where the line dividing ranges 13 and 14 strikes the bay of St. Louis, then with said line due north to the northern boundary of township 3, south, thence due east to the center of range 9; thence south to the bay of Biloxi; thence southeast to the point of Caddi; thence westwardly with the seashore and the shore of the bay of St. Louis to the beginning."
The tier of townships in Perry County, which adjoined Harrison on the north, were added to the county January 24,
1844. It took its name in honor of Gen. William Henry Harrison, then President of the United States. Its early
history is embodied in that of Hancock and Jackson counties, from which it was principally formed. In 1916 most of
the northern half of Harrison County was taken to form the new county of Stone.
Gulfport is the County seat. Biloxi is historically the oldest town in the State and was settled by the French in
1721, being the capital of the Province of Louisiana until 1722, when Bienville, then Governor, decided to move the
capital to New Orleans.
