The society grew through a combination of factors, such as population growth, technological advancement, and economic development. As the population increased, people were able to form larger and more complex communities, which allowed for the growth of agriculture, trade, and other forms of economic activity. Advances in technology, such as the development of new tools and methods of transportation, allowed for the expansion of these economic activities and facilitated the growth of the society. Over time, these factors combined to create the complex and diverse societies that we see today.
