The Guelphs and Ghibellines (/ɡwɛlfs/; /ˈɡɪbɪlaɪnz/, also US: /ˈɡɪbəliːnz/, /ˈɡɪbələnz/; Italian: guelfi e ghibellini [ˈɡwɛlfi e ɡɡibelˈliːni]) were factions supporting the Pope and the Holy Roman Emperor, respectively, in the Italian city-states of central and northern Italy. During the 12th and 13th centuries, rivalry between these two parties formed a particularly important aspect of the internal politics of medieval Italy. The struggle for power between the Papacy and the Holy Roman Empire had arisen with the Investiture Controversy, which began in 1075 and ended with the Concordat of Worms in 1122. The division between the Guelphs and Ghibellines in Italy, however, fuelled by the imperial Great Interregnum, persisted until the 15th century.
