What features were inherent in royal power in Rome?

At first, the Roman Empire was a republic, but then its structure underwent changes. The king was at the head of the state. He was elected to a special body of the Senate. The Senate included noble Romans – the descendants of the first settlers. Otherwise they were called patricians. The rest of the inhabitants were forced to obey the reforms and decrees of the emperor. He exercised power that was limited to legislative bodies. Because of this, the state was unified under the rule of the emperor. He held a high position.
