Livraga appears for the first time in September 1142, and it appears as a pledge: John, bishop of Lodi, handed over to Uberto dei Casetti a number of lands, among them those of "Luviraga", in order to borrow three hundred lire to be paid to the Milanese for the war they were waging against Como. On the name the hypotheses divide between the Celtic suffix -aga, which marks a place near water, and the Latin liber ager, free field; at the end of the sixteenth century the poet Jacopo Gabiano, in his Laudiade, chose the second, tied the name to the old freedom of the place and asked who could ever measure more wheat than Livraga.
For centuries the village belonged to the bishops of Lodi, and their small-scale administration has come down to us. On 24 September 1164, in the palace of San Salvatore in Pavia, Frederick Barbarossa confirmed to bishop Alberico the court of Livraga with its castle, its village and all its appurtenances. On 16 May 1272 bishop Bongiovanni Fissiraga granted a smith, Desenzano De Noxatello, the ferrazza, that is the right to keep a workshop and beat iron in the village. Today the fields take up about seventy per cent of the territory, the Lambro marks its western flank with the farmsteads of Panigliate and Cà dè Mazzi, and on the opposite side run the motorway and the provincial roads.
