The "King of Ragtime" in Black history is widely recognized as Scott Joplin. Born in 1868 in Texas, Joplin was a composer and pianist known for popularizing ragtime music in the late 19th and early 20th centuries. Ragtime is characterized by its syncopated rhythms and lively melodies, and Joplin's compositions, such as "Maple Leaf Rag" and "The Entertainer," became iconic pieces of the genre.

Joplin's contributions to ragtime music revolutionized American music and had a lasting impact on popular culture. He was also a trailblazer for African American composers in the classical music world, blending elements of traditional African American music with European musical styles.

Despite facing racial discrimination during his lifetime, Joplin's music has endured and continues to be celebrated today. He was posthumously awarded a Pulitzer Prize in 1976 for his contributions to American music, solidifying his legacy as the "King of Ragtime."
