Similarly, the sociologist Emile Durkheim showed that, as societies industrialize, develop, and become more modern, tasks become more specialized in terms of roles and functions. Finally, in the areas of law and governance, the great German scholar Max Weber showed how societies evolve from traditional authority (chiefs, clan heads, men on horseback) in their transitional stage, to charismatic or colorful and personality authority in transitional phases, to regularized, merit based, bureaucratic, or rational authority at a fully developed stage.
