The Titii (or Titii sodales, later Titienses, Sacerdotes Titiales Flaviales) was a college (sodalitas) of Roman priests.
One credits Titus Tatius with creating the college to superintend and preserve the Titienses, one of the three original tribes (tribus) in the Regal period,[2] which may have represented the Italic tribe of Sabines.
[3][4] The other says that Romulus created it in honour of king Tatius, who after his death was worshipped as a god.
[5] During the Republic the Titii are no longer mentioned,[6] as the cults of all Italic tribes became gradually united into Roman religion.
[7] The Titii were restored under the Empire,[8][9] but their functions were changed to conduct the worship of an emperor, like those of Sodales Augustales.
