How did the closing of Storyville in 1917 affect New Orleans jazz musicians?

The closing of Storyville in 1917 was a significant turning point for New Orleans musicians, as the district had served as a primary hub of employment for brothels, taverns, and gambling halls where early jazz flourished.21

When the federal government ordered the district closed due to its proximity to military sites during World War I, many musicians who relied on these venues for work were forced to seek opportunities elsewhere. This displacement led to a major migration of talent:231

• Riverboats: Many musicians found work in Mississippi riverboat orchestras, such as the famous ensemble led by Fate Marable, which provided a platform for artists like Louis Armstrong.3
• Chicago: A large number of musicians headed north to Chicago, which subsequently emerged as the new major urban center for jazz. Notable figures like King Oliver migrated there in 1918, eventually helping to define the Chicago style of jazz, which emphasized solo improvisation and blues influences.31
