kuker
Kukeri are Bulgarian folk characters, typically men dressed in elaborate costumes and masks, who perform rituals to drive away evil spirits and ensure a good harvest. These costumes are traditionally made of animal hides and covered with bells, often weighing several kilograms. The masks are usually frightening, designed to intimidate malevolent forces. Kukeri traditions are most prominent in the villages of southern Bulgaria and are most commonly practiced during the period between Christmas and Lent, with the main festival often occurring on the "Forgiveness" Sunday (Proshka).
The origin of kukeri rituals is believed to be ancient, possibly pre-Christian, linked to fertility rites and
