Ancient Greece and Ancient Rome had different types of governments.

Ancient Greece:
1. Structure: Ancient Greece was composed of independent city-states, each with its own government and laws. The two most well-known city-states were Athens and Sparta.
2. Principles: The main principles of the government in Ancient Greece varied from city-state to city-state. However, some common principles include:

- Athens: Athens had a system known as democracy, where eligible citizens participated in the decision-making process. All male citizens were allowed to vote and hold public office. The government was structured in such a way that power was divided among different institutions, including the Council of 500, the Assembly, and the Courts.
- Sparta: Sparta had a unique system known as the Spartan Republic, which was more of an oligarchy. Power was concentrated in the hands of a few individuals called the "Spartiates." The government was headed by two kings and consisted of a council of elders and an assembly.

Ancient Rome:
1. Structure: Ancient Rome went through different phases of government, evolving from a monarchy to a republic and eventually becoming an empire. During the republic, Rome had a system of checks and balances, with different institutions sharing power.
2. Principles: The main principles of the government in Ancient Rome include:

- Monarchy: In its early days, Rome was ruled by kings, who had supreme power. This period is known as the Roman Monarchy.
- Republic: After the monarchy, Rome established a Republic in which power was held by elected officials. The government was structured as a checks-and-balances system, with two consuls leading the executive branch, the Senate serving as the legislative branch, and various assemblies representing different groups.
- Empire: With the rise of Julius Caesar and subsequent emperors, Rome transitioned from a republic to an empire. The emperors held supreme power, and the Senate's power diminished.
