The importance of Tarquinii to archaeologists lies mainly in its necropolis, situated to the S.E.
Tarquinii is said to have been already a flourishing city when Demaratus of Corinth brought in Greek workmen.
The people of Tarquinii and Veii attempted to restore Tarquinius Superbus to the throne after his expulsion.
In 358 B.C. the citizens of Tarquinii captured and put to death 307 Roman soldiers; the resulting war ended in 351 with a forty years' truce, renewed for a similar period in 308.
When Tarquinii came under Roman domination is uncertain, as is also the date at which it became a municipality; in 181 B.C. its port, Graviscae (mod.
The flax and forests of its extensive territory are mentioned by classical authors, and we find Tarquinii offering to furnish Scipio with sailcloth in 195 B.C. A bishop of Tarquinii is mentioned in A.D.
According to the story, during the ploughing of a field near Tarquinii a being of boyish appearance sprang out of the furrow.
This twofold aspect of his character perhaps accounts for the making of two Tarquinii out of one (see Tarquinius PRlseus).
A constitutional revolution, involving such far-reaching changes, is not likely to have been carried out in primitive times with so little disturbance by a simple resolution of the people, and it probably points to a rising of Romans and Sabines against the dominion of an Etruscan family (Tarquinii, Tarchna) at that time established at Rome.
In 353, however, Caere took up arms against Rome out of friendship for Tarquinii, but was defeated, and it is probably at this time that it became partially incorporated with the Roman state, as a community whose members enjoyed only a restricted form of Roman citizenship, without the right to a vote, and which was, further, without internal autonomy.
One of the former class was the family tomb of the Tarchna-Tarquinii, perhaps descended from the Roman kings; others are interesting from their architectural and decorative details.
He is represented as the son of a Greek refugee, who removed from Tarquinii in Etruria to Rome, by the advice of his wife, the prophetess Tanaquil.
His Corinthian descent, invented by the Greeks to establish a close connexion with Rome, is impossible for chronological reasons; further, according to the genuine Roman tradition, the Tarquinii were of Etruscan, not Greek, origin.
