What role did tyrants play in the development of greek forms of government?

 In ancient Greece, tyrants were influential opportunists that came to power by securing the support of different factions of a deme. The word "tyrant" then carried no ethical censure; it simply referred to anyone who illegally seized executive power in a polis to engage in autocratic, though perhaps benevolent, government or leadership in a crisis.

Political forces often influence public opinion.
