Final answer:
The emergence of oligarchies and democracies in ancient Greece was influenced by factors such as political participation, economic prosperity, and social tensions between the aristocracy and common people.
Step-by-step explanation:
The emergence of oligarchies and democracies in ancient Greece was influenced by various factors. One major factor was the degree of political participation in the Greek city-states. Monarchy and oligarchy, characterized by government by a small group of wealthy elites, were prevalent in some city-states, while democracy, which included broader-based participation, emerged in others.
Another factor was the economic prosperity and rising wealth of the citizens. As more families became prosperous, they sought greater say in the functioning of the city-state, leading to demands for more democratic systems of government. In Athens, for example, the growing prosperity of its citizens in the eighth century BCE played a role in the development of their democratic system.
Additionally, social and economic tensions between the aristocracy and common people, or kakoi, also contributed to the emergence of oligarchies and democracies in ancient Greece. In some city-states, conflicts between the aristoi (elite landowners) and the kakoi (common people) led to the rise of populist leaders known as tyrants, who often introduced more democratic practices.
