Folk customs are one of the main components of the identity of particular nations. Their significance is visible through their existence and preservation throughout many years. Customs are subject to constant change but their foundation has remained unchanged; they are based on the oral tradition of storytelling, traditions and folk beliefs passed down from generation to generation. Folk customs include life (family), annual (holidays) and work (economic) customs. They are present in all segments of human life, especially in rural areas. People have, for a long time, tried to find different ways to mark but also protect important events and people in their lives. The customs are full of magical beliefs and rituals that serve for the above-mentioned purposes. The protection of pregnant women, children, livestock and crops, as well as Christmas, carnival, Lent and Easter customs, are just some of the folk customs discussed in more detail throughout this thesis. The century-old tradition of creating new and nurturing old folk customs has become a symbol of the Croatian people and the entire community. The uniqueness of the territory of the Republic of Croatia is reflected in the existence of folk customs that are specific and unique for this area. Overall, intangible heritage, customs, beliefs and traditions are crucial for the creation of a future that has its roots in the ancient past.
