<P> In 1433 the Duke of Milan, Filippo Maria Visconti signed a peace treaty with Florence and Venice . He then sent the condottieri Niccolò Fortebraccio and Francesco Sforza to harass the Papal States, in vengeance for Eugene IV's support to the two former republics . </P> <P> Fortebraccio, supported by the Colonna, occupied Tivoli in October 1433 and ravaged Rome's countryside . Despite the concessions made by Eugene to the Visconti, the Milanese soldiers did not stop their destruction . This led the Romans, on 29 May 1434 to institute a Republican government under the Banderesi . Eugene left the city a few days later, during the night of 4 June . </P> <P> However, the Banderesi proved incapable of governing the city, and their inadequacies and violence soon deprived them of popular support . The city was therefore returned to Eugene by the army of Giovanni Vitelleschi on 26 October 1434 . After the death in mysterious circumstances of Vitelleschi, the city came under the control of Ludovico Scarampo, Patriarch of Aquileia . Eugene returned to Rome on 28 September 1443 . </P> <Table> <Tr> <Th_colspan="2"> Rome Timeline </Th> </Tr> <Tr> <Th_colspan="2"> Renaissance and early modern Rome </Th> </Tr> <Tr> <Td> c. 1420s--1519 </Td> <Td> Rome becomes a centre of the Renaissance .
