A cultural mandate is something that a group of people think is important for their culture to share and spread. It is like an order – it tells people what they should do to keep their cultural traditions alive and to help their culture stay strong and alive. For example, in some cultures, people might have a cultural mandate that everyone should learn their language, pass down generations of stories, or make sure to practice certain rituals or traditions. It is like a way of keeping the culture alive and making sure that it is passed down throughout generations.
