What is the restriction of a culture from outside cultural influences?

The restriction of a culture from outside influences is often referred to as cultural isolation or cultural insularity. This phenomenon occurs when a society deliberately limits interactions with external cultures, which can stem from various factors such as nationalism, historical conflict, or the desire to preserve traditional values. While this can strengthen a community’s identity and traditions, it may also hinder innovation and adaptability by preventing the exchange of ideas and practices that can enrich the culture. Ultimately, such restrictions can lead to stagnation or a lack of diversity within the cultural framework.
