Please answer a question about the following article about Religion in ancient Rome:

By the end of the regal period Rome had developed into a city-state, with a large plebeian, artisan class excluded from the old patrician gentes and from the state priesthoods. The city had commercial and political treaties with its neighbours; according to tradition, Rome's Etruscan connections established a temple to Minerva on the predominantly plebeian Aventine; she became part of a new Capitoline triad of Jupiter, Juno and Minerva, installed in a Capitoline temple, built in an Etruscan style and dedicated in a new September festival, Epulum Jovis. These are supposedly the first Roman deities whose images were adorned, as if noble guests, at their own inaugural banquet.

At the end of the regal period, what class was kept out of the state political and priesthood arenas?
plebeian
