Why did the romans choose a republic as their form of government

The republic was established after a rebellion which deposed the seventh and last king of Rome, Tarquinius Superbus, who was a tyrant. The Romans decided to do away with the monarchy and swore never to let anyone try to become a king. During the Early Republic, one man was executed and another one was forced to commit suicide because there were allegations that they were trying to become kings.

Well they used that type of government because they didn't really have many governments at that time
