Dhameystir weedha soo socota: hoos u dhaca ayaa la sheegay inuu bilaabmay Agoosto 6, 1284, markii ciidankii Pisa ee tirada badnaa, ee uu hogaaminayay Albertino Morosini, ay ka adkaadeen xeeladaha cajiibka ah ee ciidankii Genoese, oo ay hogaaminayeen Benedetto Zaccaria iyo Oberto Doria, dagaalkii badda ee cajiibka ahaa
Dagaalkii Meloria. Guuldaradani waxay soo afjartay awoodda badda ee Pisa oo magaaladu weligeed si buuxda uma soo kaban; 1290, Genoese waxay burburisay Porto Pisano (dekedda Pisa), waxayna dhulka ku dabooshay cusbo. Gobolka ku xeeran Pisa uma oggolaanin magaalada inay ka soo kabato khasaaraha kumanaan badmaaxiin ah ee ka yimid Meloria, halka Liguria ay dammaanad qaaday badmaaxiin ku filan Genoa. Badeecadaha, si kastaba ha ahaatee, ayaa la sii waday in lagu ganacsado, inkasta oo tiro yar, laakiin dhamaadkii ayaa yimid markii Arno ay bilawday inay bedesho jihada, taas oo ka hortagaysa maraakiibta inay gaaraan dekedda magaalada wabiga korkiisa. Meelaha u dhow waxaa sidoo kale laga yaabaa inay ku faaftay duumada. Dhamaadkii runta ahaa wuxuu yimid 1324, markii Sardinia ay gebi ahaanba lumisay Aragonese.
