The Senate, composed of patricians, exercised the highest political and administrative power. During the mature republic, this office began to play a leading role in the state.
The last power, the executive power, was exercised by officials (magistratus) creating a magistracy with limited powers and terms of office.
Officials were divided into ordinary (ordinarii) regularly elected for terms of office:
- Consuls – there were two of them, army commanders. The highest Roman officials became governors of the most important provinces. They had the legislative initiative.
- Praetors – supervised the judiciary, judges.
- Censors – appointed for 1, 5 years every 5 years. They kept a census (property status, number of children) and drew up lists of senators. They took care of the Rome budget and guarded the morality of the citizens.
- Aediles – dealt with public order (e.g. cleaning streets), organized games and distributed grain. They held their office for a year.
