Latin is an Italic language that was used in Ancient Rome. Short Latin texts have been found from about the 5th century BC and longer texts from about the 3rd century BC.

Classical Latin was used in the 1st century BC and was the official language of the Roman Empire. It was widely used in the western part of the Mediterranean. The languages known as Romance languages developed from the spoken, informal version, called Vulgar Latin.

Latin was very important to Christianity for many centuries. It is still spoken today during some religious activities. It is an official language in the Vatican, where the Pope leads the Roman Catholic Church. People in the Vatican sometimes speak to one another in Latin (if they have different first languages). The mass of the Catholic Church may be done entirely in Latin. This is the Mass of the Roman Rite (Extraordinary Form).
