Rome was founded in 753 BC by the twin brothers Romulus and Remus. According to legend, the twins were abandoned as infants and raised by a she-wolf. As adults, they argued over where to build a city, during which Romulus killed Remus. Romulus went on to found Rome and become its first king. Rome later unified Italy in 1870 and remains the capital today, with a population that is over 90% Italian.
