As we saw in class, Rome started being a monarchy. There were seven kings during the monarchy. The first one was Romulus and the last one was Lucius Superbus. During the monarchy, the king was vey powerful and he had control over the army, the government and was the high priest.
The king was very powerful and the inhabitants felt so bad that in the 6th there was a rebellion against L. Superbus and he was killed.
That was the end of the monarchy and the beginning of a new period: the Republic.
