Prior to the establishment of modern Zambia, the inhabitants lived in independent tribes, each with its own way of life. One of the results of the colonial era was the growth of urbanisation. Different ethnic groups started living together in towns and cities, influencing each other's way of life. They also started adopting aspects of global or universal culture, especially in terms of dressing and mannerisms. Much of the original cultures of Zambia have largely survived in rural areas, with some outside influences such as Christianity. Cultures that are specific to certain ethnic groups within Zambia are known as 'Zambian cultures' while those lifestyles that are common across ethnic groups are labelled "Zambian culture" because they are practiced by almost every Zambian. In the urban setting, there is a continuous integration and evolution of these cultures to produce what is called "Zambian culture".
