A masquerade is a festive gathering where participants wear masks and elaborate costumes, often to conceal their identities. This tradition dates back to the 15th century in Europe, particularly during the Carnival season. Masquerades can include dancing, music, and socializing, creating an atmosphere of mystery and excitement. In addition to social events, masquerades have been depicted in literature and art, symbolizing themes of disguise and deception. Famous examples include the Masquerade Ball in The Phantom of the Opera and the Masquerade in Romeo and Juliet. These events often explore the contrast between appearance and reality.
