History.
Franklin, named for Benjamin Franklin, was founded in 1808 as the "Carlin's Settlement" by French-born pioneer Joseph Carlin and his family. It became the parish seat in 1811 and the town was incorporated in 1820. Though early settlers included French, Acadian, German, Danish and Irish, the town's culture and architecture is heavily influenced by the unusually large numbers of English that chose to settle there after the Louisiana Purchase in 1803.
Numerous large sugar plantations arose in the area, and with the development of steam-boating, Franklin became an interior sugar port. With the later advent of the railroad, it became a sawmill town.
Franklin's First United Methodist Church was established in 1806, making it the first Protestant church established in the state of Louisiana.
Sugar plantations.
By the 1830s, Bayou Teche was the main street of Acadiana, with one plantation after another. The area's sugar cane planters were among the South's wealthiest agriculturists. This is reflected in the grand plantation homes and mansions they built in Franklin and the surrounding countryside. Most of these magnificent structures are still standing and well preserved, giving Franklin its unique architectural flavor.
Franklin's Historic District is listed in the National Register of Historic Places (NRHP) and encompasses over 420 notable structures. Some of the historic plantations in Franklin listed in the NRHP include the Alice C. Plantation House, Arlington Plantation House, and the Dixie Plantation House.
Civil War.
During the Civil War, the Battle of Irish Bend, also known as Nerson's Woods, was fought near Franklin on April 14, 1863. Though eventually forced to retreat, the badly outnumbered Confederate forces commanded by General Richard Taylor cost the Union troops, under General Cuvier Grover, significant losses. Four hundred men were killed or wounded in the confrontation, including Confederate Colonel James Reily, a factor in halting the Union drive to invade Texas.
