The acronym “SPQR” is an initialism of the Latin phrase, “Senatus Populusque Romanus” which means “The Roman Senate and People”. Latin was the primary language spoken by the ancient Romans, alongside many other lesser spoken languages as the Roman empire was a vast and diverse nation state with tolerance for culture, language, and religion. Today SPQR is still used as the official emblem of the modern day commune/municipality of Rome
