of the latter as well as the Acadians, (Acadians are those who became known as "Cajuns.") A number of common Cajun surnames have German origins: for example, Schexnayder (various spellings), LaBranche (a calque of Zweig), Folse, Zeringue (Zehring), Hymel (Himmel), and Trosclair (a phonetic macaronic of Troxler). The Germans are also credited with introducing the accordion into Cajun music. History 18th century In the Louisiana Rebellion of 1768, German colonists joined with Acadians from the Cabannocé Post area to march on New Orleans and overthrow the new Spanish colonial governor Antonio de Ulloa. Between 1769 and 1777, Governor Luis de Unzaga Amezaga 'le Conciliateur' promoted the colonization of the extensive province of Louisiana and distributed land and agricultural tools to the European families who came to live there. Unzaga created the world's first bilingual public educational system in New Orleans and also allowed various peoples to continue speaking in various languages such as English on the eastern bank of the Mississippi or German on the German coast. Starting in the late 1770s, the German and Acadian settlers united again, under Spanish colonial governor Bernardo de Gálvez, to fight the British during the American Revolutionary War. 19th century In 1811, the German Coast was the site of the largest slave revolt in US history, the 1811 German Coast uprising.

The rebellion's leaders were slaves Quamana and Harry, and Charles Deslondes, a free man of color. They gathered an estimated 500 slaves from plantations along the River Road and marched toward New Orleans.

The local militia was called out and killed nearly half of the total ninety-five slaves who died as a result of the rebellion. The remainder were executed after tribunals were held in the parishes, including Orleans Parish. 20th century During World War I, in a reaction against Germany as the enemy, the Louisiana state legislature passed Act 114: it prohibited all expressions of German culture and heritage in the state, especially the printed or spoken use of the German language.
