Louisiana

• 1. Introduction

  ›

  Louisiana sits at one of the most consequential crossroads in North America, where the Mississippi River meets the Gulf of Mexico. Long before a single European ship appeared on the horizon, thousands of years of human civilization had already shaped this land. The state that would emerge here would speak multiple languages, worship under different traditions, divide itself into parishes instead of counties, and rank 31st in area while carrying a cultural weight far beyond its size. What made this particular stretch of swamp, delta, and prairie the site of such a layered history? And why, after centuries of upheaval, does Louisiana still feel unlike anywhere else in the United States? The answers reach back to the 4th millennium BC, pass through Napoleon's war chest, and run straight through the levees that failed on the 29th of August 2005.

• 2. Deep Roots in the Land

  ›

  The Watson Brake site, near present-day Monroe, contains an eleven-mound complex built roughly 5,400 years ago. When archaeologists confirmed its age, it forced a rethinking of a long-held assumption: that large earthwork constructions could only be built by settled, maize-dependent societies. The hunters and gatherers who raised those mounds in northern Louisiana were organizing complex collective labor without farming.

  Poverty Point came nearly two thousand years later and went further still. Possibly the first complex culture in North America, it may have reached its peak around 1500 BC, lasting until approximately 700 BC. The modern city of Epps grew up near its ruins. The Tchefuncte culture that followed was the first in this region to produce pottery in large quantities.

  By the Middle Woodland period, the Marksville culture had spread across the southern and eastern parts of the state, trading through the Hopewell Exchange Network and receiving the bow and arrow from peoples to the southwest. The Marksville Prehistoric Indian Site in Avoyelles Parish gives the culture its name.

  By 1200, the Plaquemine culture had taken hold in the lower Mississippi River Valley, lasting to about 1600. Its descendants encountered Europeans in the colonial era as the Natchez and Taensa peoples. In the northwest of the state, the Caddoan Mississippian culture had deep roots that carried unbroken into the present: the modern Caddo Nation of Oklahoma traces its ancestry directly to those prehistoric communities. Many of Louisiana's place names today, including Atchafalaya, Caddo, Houma, and Natchitoches, are transliterations from those Native American languages.

• 3. France, Spain, and the Shape of the Colony

  ›

  A Spanish expedition led by Pánfilo de Narváez reached the mouth of the Mississippi River in 1528, the first Europeans to do so. Hernando de Soto's men skirted the northern and western edges of the region in 1542-43, then Spanish interest largely faded for over a century.

  France moved differently. In 1682, René-Robert Cavelier, Sieur de La Salle, claimed the entire territory drained by the Mississippi for France and named it La Louisiane after King Louis XIV, who reigned from 1643 to 1715. The name's Latin suffix carries the sense of "related to Louis." The first permanent settlement, Fort Maurepas at what is now Ocean Springs, Mississippi, was founded in 1699 by Pierre Le Moyne d'Iberville. By 1714, the settlement at Natchitoches along the Red River had been established by Louis Juchereau de St. Denis, making it the oldest permanent European settlement in the modern state. New Orleans was developed from 1722 as the seat of civilian and military authority south of the Great Lakes.

  At its broadest, a royal ordinance of 1722 defined Louisiana as all land France claimed south of the Great Lakes between the Rocky Mountains and the Alleghenies. That vast territory eventually shrank through treaty. France ceded its lands east of the Mississippi to Great Britain in 1763 following the Seven Years' War. The rest, along with New Orleans, passed to Spain by the Treaty of Fontainebleau in 1762.

  Spanish rule lasted until 1800. In 1765, the governor Luis de Unzaga y Amézaga welcomed thousands of Acadians expelled by the British from what is now Nova Scotia, New Brunswick, and Prince Edward Island. They settled chiefly in the southwestern region now called Acadiana and became the ancestors of Louisiana's Cajuns. Spanish Canary Islanders emigrated between 1778 and 1783. Then in 1800, Napoleon quietly reacquired the territory through the Treaty of San Ildefonso, keeping the arrangement secret for two years.

• 4. The Purchase That Doubled a Nation

  ›

  Napoleon had ambitions in the Caribbean. He looked upon Louisiana as a supply depot for the sugar islands of Martinique and Guadeloupe, returned to France under the Treaty of Amiens in 1802. But his brother-in-law Leclerc's army was defeated trying to retake Saint-Domingue from Toussaint Louverture, and with that defeat, Napoleon's American dreams collapsed.

  Thomas Jefferson, the third president, had authorized Robert R. Livingston to negotiate for the purchase of New Orleans and nearby land, with a ceiling of $2 million. On the 11th of April 1803, French foreign minister Talleyrand asked Livingston unexpectedly whether the United States would consider buying the entire Louisiana Territory. Livingston and James Monroe, sent as a special envoy, judged that Napoleon might withdraw the offer before Jefferson could respond. By the 30th of April they had closed a deal: the entire 828,000 square miles of Louisiana for sixty million francs, roughly $15 million, less than three cents an acre.

  Part of the sum, $3.5 million, was used to forgive French debts to the United States. Napoleon sold the American bonds at a discount to the Dutch firm of Hope and Company and the British banking house of Baring. France ultimately received $8,831,250 in cash. Alexander Baring himself carried the bonds from the United States to Britain and returned with the money, which Napoleon then used to wage war against Baring's own country.

  The U.S. Senate ratified the treaty on the 20th of October 1803. A transfer ceremony was held in New Orleans on the 29th of November 1803. The Spanish took down their flag; the French raised theirs; the following day General James Wilkinson accepted possession for the United States. The territory was divided along the 33rd parallel north on the 26th of March 1804. Louisiana became the 18th state on the 30th of April 1812.

• 5. Slavery and Its Economy

  ›

  Jean-Baptiste Le Moyne, Sieur de Bienville, brought the first two African slaves to Louisiana in 1708, transported from a French colony in the West Indies. By 1724, the French government had issued the Code Noir, regulating the interaction of white and Black residents across the colony.

  In 1719, two French ships, the Du Maine and the Aurore, arrived in New Orleans carrying more than 500 enslaved people from Africa. By the end of 1721, New Orleans counted 1,256 inhabitants, of whom roughly half were slaves. The settlement of Natchitoches had already become a flourishing river port where vast cotton plantations were worked by imported African labor.

  By 1840, New Orleans held the largest slave market in the United States, making it one of the wealthiest and the third-largest city in the nation. More than one million enslaved African Americans underwent forced migration from the Upper South to the Deep South in the decades after the Revolutionary War; two thirds of them passed through the slave trade. Steamboats operating on the Mississippi carried people from New Orleans upstream to markets at Natchez and Memphis.

  According to the 1860 census, 331,726 people in Louisiana were enslaved, nearly 47% of the state's total population of 708,002. Louisiana seceded from the Union on the 26th of January 1861, and became one of the seven original members of the Confederate States of America. Federal troops captured New Orleans on the 25th of April 1862, cutting the Confederacy's hold on the Mississippi River sooner than most of the state's leaders had anticipated.

  Louisiana also harbored escaped Filipino slaves from the Manila Galleons, known as Manila men or Manilamen. They established the oldest settlement of Asians in the United States at the village of Saint Malo, Louisiana, and fought alongside Jean Lafitte against the British in the War of 1812.

• 6. Reconstruction, Suppression, and Migration

  ›

  Oscar Dunn and P.B.S. Pinchback became the United States' first and second Black governors during Reconstruction, when 125 Black members of the state legislature were elected. Charles E. Nash was elected to represent the state's 6th Congressional District in the U.S. House of Representatives during the same period.

  That window closed quickly. By the late 1870s, former Confederates had regained control of the state legislature. The White League suppressed Black voting through intimidation and violence. In 1896, there were 130,334 Black voters registered in Louisiana. By 1900, after a new constitution raised barriers through poll taxes, residency requirements, and literacy tests, that number had fallen to 5,320. By 1910, only 730 Black voters remained registered, less than 0.5 percent of eligible African-American men.

  Governor Huey Long, elected during part of the Great Depression on populist appeal, represented a different kind of disruption. His public works projects created thousands of jobs and he expanded educational access, but he was widely criticized for autocratic and demagogic tendencies and extended patronage control through every branch of state government. His rule ended abruptly when he was assassinated in the state capitol in 1935.

  Violent white resistance in Bogalusa to Black residents trying to use public facilities in 1965, following passage of the Civil Rights Act of 1964, led the federal government to order local police to protect the activists. This same resistance had already catalyzed the founding of the Deacons for Defense and Justice in Jonesboro and Bogalusa in late 1964 and early 1965. Made up of veterans of World War II and the Korean War, these were armed self-defense groups protecting activists and their families.

• 7. A Land in Retreat

  ›

  From 1932 to 2010, Louisiana lost 1,800 square miles of land to rising sea levels and erosion. Some researchers estimate the state is currently losing a landmass equivalent to 30 football fields every day. The Louisiana Coastal Protection and Restoration Authority spends around $1 billion per year in combined federal and state funding to slow that loss.

  Artificial levees block the spring floodwaters that once carried fresh water and sediment to marshes. Logging of cypress swamps left canals that allow saltwater to move inland. Canals dug for the oil and gas industry carry storm surges deeper into wetlands. The Gulf of Mexico dead zone off the Louisiana coast was 8,776 square miles in 2017, the largest ever recorded.

  On the 29th of August 2005, Hurricane Katrina struck New Orleans and much of the surrounding Gulf coast. Levee breaches caused large-scale flooding of more than 80% of the city. Tens of thousands of people, many of them African American, stayed behind, some stranded without means to leave.

  In August 2016, an unnamed storm dropped trillions of gallons of rain on southern Louisiana, striking Denham Springs, Baton Rouge, Gonzales, St. Amant, and Lafayette. An estimated 110,000 homes were damaged. The loss of coastal wetlands threatens not only communities but the economically significant coastal fishery that depends on them. Louisiana's highest elevation is Driskill Mountain, only 535 feet above sea level, making the state's vulnerability to both storms and rising water a structural fact of the land itself.

• 8. Culture Layered Over Time

  ›

  In 1921, English was made the sole language of instruction in Louisiana schools. A policy of multilingualism was revived in 1974, and Louisiana has never formally adopted an official language. Its state constitution explicitly enumerates the right of people to preserve, foster, and promote their historic, linguistic, and cultural origins.

  Louisiana is the only U.S. state with political subdivisions called parishes rather than counties, a legacy of French Catholic administration. Its legal system traces roots to the Code Noir of 1724 and French civil law that survived the Louisiana Purchase, including the prohibition of cruel punishment. Reflecting French and Spanish heritage, dialects spoken in the state include Cajun English, New Orleans English, and variants of Southern American English, with common dropping of the postvocalic r in the southern half.

  Beginning in the 1790s, waves of refugees from the Saint-Domingue slave rebellion of 1791 landed in Louisiana, including Europeans, Creoles, and Africans. The governor Pierre Clément de Laussat, serving in 1803, observed that Saint-Domingue was "of all our colonies in the Antilles, the one whose mentality and customs influenced Louisiana the most." Their arrival greatly increased both the French-speaking population and the presence of African culture in New Orleans.

  Today Louisiana supplies approximately 90% of the world's crawfish. The Port of South Louisiana, between New Orleans and Baton Rouge, was the largest volume shipping port in the Western Hemisphere and the 4th largest in the world as of 2004. State financial incentives introduced in 2002 have made Louisiana a major film production hub, earning it the nickname "Hollywood South." Tabasco sauce originated at Avery Island, where the McIlhenny Company still operates. Louisiana's gross state product reached $340 billion in 2025, while the state continues to rank among the lowest in the nation on health and educational metrics, with the highest homicide rate in the United States recorded at least since the 1990s.
