Answer:
B C and E
Explanation:
- Greece benefited from city-states for the following reasons:
They each developed their military forces making Greece a military powerhouse.
Citizens of Ancient Greece fought to defend their cities, they were called hoplites (spearmen that had combat in a special formation called phalanx). Each city-state was responsible for the defence of the island and having an own ruler with an own military force combined forces when a major effort in the war was imminent: example war between Greece and Persia.
- The rivalry between city-states meant more political interest among citizens.
Each city-state possessed unique symbols representing a local identity, being autonomous and self-governed. Often differences between them enabled a unique political engagement from most of the citizens.
Decisions were carried by the citizens of every polis and small differences were respected and considered based on that island needs.
Sparta, for example, was the biggest polis, having the greatest territory and developed a major policy for converting citizens into the best-developed warriors
- They were active in the polis with each having a local centre with a leader for a particular political-economic and cultural participation.
In their political engagement were the roots of democracy.
Democracy developed in Athens with a politician and thinker Pericles, who is well known for his initiative to promote decision taking with the general assemble- In Greece, every citizen was able to participate in decision making for the policy of their city. Athens became the major centre of democratic innovations.
