SPQR
SPQR is an acronym of a Latin phrase, Senātus Populusque Rōmānus ("The Roman Senate and People"; Classical Latin: [sɛˈnaː.tʊs pɔpʊˈlʊs.kᶣɛ roːˈmaː.nʊs]), referring to the government of the ancient Roman Republic, and used as an official emblem of the modern-day comune (municipality) of Rome. It appears on Roman currency, at the end of documents made public by inscription in stone or metal, in dedications of monuments and public works, and was emblazoned on the vexilloids of the Roman legions.
