First Period: from the foundation of the city, to the establishment of the plebeian order. Niebuhr's researches into the early history of Rome have established it as a fact beyond all doubt, that during this period the patricians comprised the whole body of Romans who enjoyed the full franchise, that they were the
populus Romanus, and that there were no other real citizens besides them (Niebuhr,
Hist. of Rome,
II. pp224, 225, note 507;
Cic. pro Caecin. 35). The patricians must be regarded as conquerors who reduced the earlier inhabitants of the places they occupied to a state of servitude, which in our authorities is designated by the terms
cliens and
plebs. The other parts of the Roman population, namely clients and slaves, did not belong to the
populus Romanus, or sovereign people, and were not burghers or patricians. The senators were a select body of the
populus or patricians, which acted as their representative. The burghers or patricians consisted originally of three distinct tribes, which gradually became united into the sovereign
populus. These tribes had founded settlements upon several of the hills which were subsequently included within the precincts of the city of Rome. Their names were
Ramnes,
Tities, and
Luceres, or
Ramnenses,
Titienses, and
Lucerenses. Each of these tribes consisted of ten
curiae, and each
curia of ten decuries, which were established for representative and military purposes [
Senatus.] The first tribe, or the
Ramnes, were a Latin colony on the Palatine hill, said to have been founded by Romulus. As long as it stood alone, it contained only one hundred
gentes, and had a senate of one hundred members. When the
Tities, or Sabine settlers on the Quirinal and Viminal hills, under king Tatius, became united with the Romans, the number of
gentes as well as that of senators was increased to 200. These two tribes after their union continued probably for a considerable time to be the patricians of Rome, until the third tribe, the
Luceres, which chiefly consisted of Etruscans, who had settled on the Caelian Hill, also became united with the other two as a third tribe. When this settlement was made is not certain: some say that it was in the time of Romulus (Festus,
s.v. Caelius Mons and
Luceres;
Varro, de Ling. Lat. V.55); others that it took place at a later time (
Tacit. Ann. IV.65; Festus,
s.v. Tuscum vicum). But the Etruscan settlement was in all probability older than that of the Sabines (see Göttling,
Gesch. der Röm. Staatsverf. p54, &c.), though it seems occasionally to have received new bands of Etruscan settlers even as late as the time of the republic. The amalgamation of these three tribes did not take place at once: the union
