The Roman Senate was a governing and advisory assembly in ancient Rome. It was one of the most enduring institutions in Roman history, being established in the first days of the city of Rome (traditionally founded in 753 BC).
Romulus was Rome's founder and first king. After he and his twin brother Remus had deposed King Amulius of Alba and reinstated the king's brother and their grandfather Numitor to the throne, they decided to build a city in the area where they had been abandoned as infants. After killing Remus in a dispute, Romulus began building the city on Palatine Hill. His work began with fortifications. He permitted men of all classes to come to Rome as citizens, including slaves and freemen without distinction.
