Minstrelsy was a form of entertainment popular in the United States during the 19th century, characterized by performances that included music, dance, and comedy. It often featured white performers in blackface, portraying caricatures of African Americans. This genre was influential in shaping American popular culture but also perpetuated harmful stereotypes. The minstrel shows typically included a variety of acts, such as singing, dancing, and skits. Notable figures in minstrelsy included Stephen Foster, who composed many songs associated with the genre, and Al Jolson, a famous performer who later became known for his role in the first feature-length sound film, The Jazz Singer.
