New Orleans in the context of "Louisiana in the American Civil War"

Jazz is a music genre that originated in the African-American communities of New Orleans, Louisiana, in the late 19th and early 20th centuries. Its roots are in blues, ragtime, European harmony, African rhythmic rituals, spirituals, hymns, marches, vaudeville song, and dance music. Since the 1920s Jazz Age, it has been recognized as a major form of musical expression in traditional and popular music. Jazz is characterized by swing and blue notes, complex chords, call and response vocals, polyrhythms and improvisation.

As jazz spread around the world, it drew on national, regional, and local musical cultures, which gave rise to different styles. New Orleans jazz began in the early 1910s, combining earlier brass band marches, French quadrilles, biguine, ragtime and blues with collective polyphonic improvisation. However, jazz did not begin as a single musical tradition in New Orleans or elsewhere. In the 1930s, arranged dance-oriented swing big bands, Kansas City jazz (a hard-swinging, bluesy, improvisational style), and gypsy jazz (a style that emphasized musette waltzes) were the prominent styles. Bebop emerged in the 1940s, shifting jazz from danceable popular music toward a more challenging "musician's music" which was played at faster tempos and used more chord-based improvisation. Cool jazz developed near the end of the 1940s, introducing calmer, smoother sounds and long, linear melodic lines.

The Gulf Coast of the United States, also known as the Gulf South or the South Coast, is the coastline along the Southern United States where they meet the Gulf of Mexico. The coastal states that have a shoreline on the Gulf of Mexico are Texas, Louisiana, Mississippi, Alabama, and Florida, and these are known as the Gulf States.

The economy of the Gulf Coast area is dominated by industries related to energy, petrochemicals, fishing, aerospace, agriculture, and tourism. The large cities of the region are (from west to east) Brownsville, Corpus Christi, Houston, Galveston, Beaumont, Lake Charles, Lafayette, Baton Rouge, New Orleans, Gulfport, Biloxi, Mobile, Pensacola, Panama City, St. Petersburg, and Tampa. All are the centers or major cities of their respective metropolitan areas and many contain large ports.

Louisiana (Spanish: Luisiana, [la lwiˈsjana]) was a province of New Spain from 1762 to 1801. It was primarily located in the center of North America encompassing the western basin of the Mississippi River plus New Orleans. The area had originally been claimed and controlled by France, which had named it La Louisiane in honor of King Louis XIV in 1682. Spain secretly acquired the territory from France near the end of the Seven Years' War by the terms of the Treaty of Fontainebleau (1762). The actual transfer of authority was a slow process, and after Spain finally attempted to fully replace French authorities in New Orleans in 1767, French residents staged an uprising which the new Spanish colonial governor did not suppress until 1769. Spain also took possession of the trading post of St. Louis and all of Upper Louisiana in the late 1760s, though there was little Spanish presence in the wide expanses of what they called the "Illinois Country".

New Orleans was the main port of entry for Spanish supplies sent to American forces during the American Revolution, and Spain and the new United States disputed the borders of Louisiana and navigation rights on the Mississippi River for the duration of Spain's rule in the colony. New Orleans was devastated by large fires in 1788 and 1794 which destroyed most of the original wooden buildings in what is today the French Quarter. New construction was done in the Spanish style with stone walls and slate roofs, and new public buildings constructed during the city's Spanish period include several still standing today such as the St. Louis Cathedral, the Cabildo, and the Presbytere.

The Union blockade in the American Civil War was a naval strategy by the United States to prevent the Confederacy from trading.

The blockade was proclaimed by President Abraham Lincoln in April 1861, and required the monitoring of 3,500 miles (5,600 km) of Atlantic and Gulf coastline, including 12 major ports, notably New Orleans and Mobile. Those blockade runners fast enough to evade the Union Navy could carry only a small fraction of the supplies needed. They were operated largely by British and French citizens, making use of neutral ports such as Havana, Nassau and Bermuda. The Union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.

Louisiana (French: Louisiane [lwizjan]; Spanish: Luisiana [lwiˈsjana]; Louisiana Creole: Lwizyàn) is a state in the Deep South and South Central regions of the United States. It borders Texas to the west, Arkansas to the north, and Mississippi to the east. Of the 50 U.S. states, it ranks 31st in area and 25th in population, with roughly 4.6 million residents. Reflecting its French heritage, Louisiana is the only U.S. state with political subdivisions termed parishes, which are equivalent to counties, making it one of only two U.S. states not subdivided into counties (the other being Alaska and its boroughs). Baton Rouge is the state's capital, and New Orleans, a French Louisiana region, is its most populous city with a population of about 363,000 people. Louisiana has a coastline with the Gulf of Mexico to the south; a large part of its eastern boundary is demarcated by the Mississippi River and the mouth of the Mississippi or delta defines much of its lower topography.

Much of Louisiana's lands were formed from sediment washed down the Mississippi River, leaving enormous deltas and vast areas of coastal marsh and swamp. These contain a rich southern biota, including birds such as ibises and egrets, many species of tree frogs—such as the state-recognized American green tree frog—and fish such as sturgeon and paddlefish. More elevated areas, particularly in the north, contain a wide variety of ecosystems such as tallgrass prairie, longleaf pine forest and wet savannas; these support an exceptionally large number of plant species, including many species of terrestrial orchids and carnivorous plants. Over half the state is forested.

The Walls of Old San Juan (Spanish: Murallas del Viejo San Juan) is a defensive city wall that surrounds the western end of the San Juan Islet, site of the historic district of San Juan, Puerto Rico. This defensive wall system was built between the 16th and 18th centuries to protect the city and the Bay of San Juan, a highly strategic point in the Caribbean. These walls, along with the defensive fortresses in Old San Juan (La Fortaleza, El Morro and San Cristóbal), form part of the UNESCO World Heritage Site-designated San Juan National Historic Site as they are characteristic examples of the historic methods of construction used in military architecture which adapted European designs and techniques to the special conditions of the Caribbean port cities.

San Juan remains the only walled city under the United States jurisdiction, with walled cities like Boston, Charleston and New Orleans no longer having walls after the 18th century, although St. Augustine, Florida, still retains several wall remnants. Examples of other North American walled cities that retain their ramparts are Quebec City in Canada and Campeche in Mexico. The bartizans (garitas) found along the walls are considered emblematic of the city of San Juan and a symbol of historic heritage preservation in Puerto Rico.

In the British colonies in North America and in the United States before the abolition of slavery in 1865, free Negro or free Black described the legal status of African Americans who were not enslaved. The term was applied both to formerly enslaved people (freedmen) and to those who had been born free (free people of color), whether of African or mixed descent.

The Supreme Court of Louisiana (French: Cour suprême de Louisiane; Spanish: Corte Suprema de Luisiana) is the highest court and court of last resort in the U.S. state of Louisiana. The modern Supreme Court, composed of seven justices, meets in the French Quarter of New Orleans.

The Supreme Court, and Louisiana state law, are historically based in the colonial governments of France and Spain during the 18th century. The current Supreme Court traces its roots back to these beginnings.

The American Mafia, commonly referred to in North America as the Italian-American Mafia, the Mafia, or the Mob, is a highly organized Italian-American criminal society and organized crime group. The terms Italian Mafia and Italian Mob apply to these American-based organizations, as well as the separate yet related Sicilian Mafia or other organized crime groups in Italy, or ethnic Italian crime groups in other countries. These organizations are often referred to by its members as Cosa Nostra (Italian pronunciation: [ˈkɔːza ˈnɔstra, ˈkɔːsa -]; lit. 'Our Thing') and by the American government as La Cosa Nostra (LCN). The organization's name is derived from the original Mafia or Cosa Nostra, the Sicilian Mafia, with "American Mafia" originally referring simply to Mafia groups from Sicily operating in the United States.

The Mafia in the United States emerged in impoverished Italian immigrant neighborhoods in New York's East Harlem (or "Italian Harlem"), the Lower East Side, and Brooklyn; also emerging in other areas of the Northeastern United States and several other major metropolitan areas (such as Chicago and New Orleans) during the late 19th century and early 20th century, following waves of Italian immigration especially from Sicily and other regions of Southern Italy. Campanian, Calabrian and other Italian criminal groups in the United States, as well as independent Italian-American criminals, eventually merged with Sicilian Mafiosi to create the modern pan-Italian Mafia in North America. Today, the Italian-American Mafia cooperates in various criminal activities with Italian organized crime groups, such as the Sicilian Mafia, the Camorra of Campania and the 'Ndrangheta of Calabria. The most important unit of the American Mafia is that of a "family", as the various criminal organizations that make up the Mafia are known. Despite the name of "family" to describe the various units, they are not familial groupings.
