A mystic society is a Mardi Gras social organization in Mobile, Alabama, that presents parades and/or balls for the enjoyment of its members, guests, and the public. The New Orleans Krewe is patterned after Mobile's Mystics. The societies have been based in class, economic and racial groups. Mobile's parading mystic societies build colorful Carnival floats and create costumes around each year's themes.
During the Carnival season, the mystic societies parade in costume on their floats throughout downtown Mobile. Masked society members toss small gifts, known as throws, to the parade spectators. The throws can take the form of trinkets, candy, cookies, peanuts, panties, artificial roses, stuffed animals, doubloons, cups, hats, can coolers, Frisbees, medallion necklaces, bead necklaces of every variety, and Moon Pies.
Mystic societies in Mobile give formal masquerade balls, known as bal masqués, which are almost always invitation only and are oriented to adults. Attendance at a ball requires that a strict dress code be followed that usually involves full-length evening gowns and white tie with tails for invited guests, and masked costumes for society members. The bal masqués feature dramatic entertainment, music, dancing, food, and drinks. Bal masqués are normally based on a theme which is carried out through scenery, decorations, and costumes. Some society balls also include a tableau vivant. Much of the memorabilia from these occasions can be viewed at the Mobile Carnival Museum.
Mobile first celebrated Carnival in 1703 when French settlers began the festivities at the Old Mobile Site. Mobile's first informal Carnival society was organized in 1711 with the Boeuf Gras Society (Fatted Ox Society). Since that time mystic societies have evolved into much more complex organizations and membership has been formed by various social groups, originally based in class and related alignments. Groups have been formed by co-workers, bachelors, women, African Americans, Jews, married women, married couples, gays and lesbians, or open membership, including visitors.
