A mother culture is a term for an early people and their culture, with great and widespread influence on later cultures and people. Though the original culture may fade, the mother culture's influence grows for ages in the future. Later civilizations either learn and build upon their old ways, or can learn them through peaceful or military assimilation. This term can be found in the novel Ishmael by Daniel Quinn.
A mother culture is what gives birth to a culture , although it does not necessarily start up its customs it is the root that gives rise to a grand fruit tree otherwise known as society that can be traced back to its mother. This tree might undergo a catastrophe that will cause all its societies that sprung up to shrivel away but the mother culture is what we attribute to their origins.
Mother cultures in history include that of Kemet in the Mediterranean, and the Olmec in Mesoamerica.
