Lorenzo's power in Florence and influence throughout Italy was now secure. By the institution in 1480 of a Council of Seventy, a permanent council to manage and control the election of the Signoria (with two special committees drawn from the Seventy every six months, the _Otto di pratica_ for foreign affairs and the _Dodici Procuratori_ for internal), the State was firmly established in his hands--the older councils still remaining, as was usual in every Florentine reformation of government. Ten years later, in 1490, this council showed signs of independence; and Lorenzo therefore reduced the authority of electing the Signoria to a small committee with a reforming Balìa of seventeen, of which he was one. Had he lived longer, he would undoubtedly have crowned his policy either by being made Gonfaloniere for life, or by obtaining some similar constitutional confirmation of his position as head of the State. Externally his influence was thrown into the scale for peace, and, on the death of Sixtus IV. in 1484, he established friendly relations and a family alliance with the new Pontiff, Innocent VIII. Sarzana with Pietrasanta were won back for Florence, and portions of the Sienese territory which had been lost during the war with Naples and the Church; a virtual protectorate was established over portions of Umbria and Romagna, where the daggers of assassins daily emptied the thrones of minor tyrants. Two attempts on his life failed. In the last years of his foreign policy and diplomacy he showed himself truly the magnificent. East and West united to do him honour; the Sultan of the Turks and the Soldan of Egypt sent ambassadors and presents; the rulers of France and Germany treated him as an equal. Soon the torrent of foreign invasion was to sweep over the Alps and inundate all the "Ausonian" land; Milan and Naples were ready to rend each other; Ludovico Sforza was plotting his own rise upon the ruin of Italy, and already intriguing with France; but, for the present, Lorenzo succeeded in maintaining the balance of power between the five great Italian states, which seemed as though they might present a united front for mutual defence against the coming of the barbarians.
