Hancock County History

Hancock County was originally established in the territorial period, on December 14, 1812. Some of its territory went for the formation and expansion of Pearl River County in 1890 and 1908, respectively. The county now has an area of 469 square miles.

Hancock County was named in honor of John Hancock, and has had a varied and romantic history. The coast region along its southern border was first discovered by the Spaniards and later rediscovered by La Salle and colonized by Iberville for the French. A part of the great French Province of Louisiana for a time, by the treaty of Paris in 1763, it became a British possession and was incorporated with the newly established province of West Florida. It was not until early in the nineteenth century that the settlements of the whites penetrated far into the interior of the county from the coast, as all of southern Mississippi was up to that time in the actual occupancy of the Indians.

Under the treaties of Fort Adams, December 17, 1801, and Mount Dexter, November 16, 1805, the Indians relinquished to the United States all the southern portion of the present State of Mississippi, and May 14, 1812, the district of Mobile, lying east of Pearl River, West of the Perdido and south of the 31st degree of latitude, was annexed to the Mississippi territory. A few months later, December 14, 1812, all that part of this region lying within the present limits of Mississippi, was erected into the two large counties of Hancock and Jackson. The original act defined the limits of Hancock as follows:

"All that tract of country lying south of the 31st degree of north latitude and west of the line running due north from the middle of the Bay of Biloxi to the 31st degree of north latitude and east of the Pearl River."

February 5, 1841, that portion of Hancock lying east of the line between ranges 13 and 14 was embodied in the county of Harrison, and February 22, 1890, that portion of the county lying north of the dividing line between townships 4 and 5, and extending from the middle of Pearl River east to the line between ranges 13 and 14 west, was taken to form the new county of Pearl River.

The County Courthouse was destroyed by fire in 1853, All records were destroyed. The county was severely damaged from Hurricane Katrina on August 28-29, 2005, causing catastrophic effects.
