See also: Treaty of Basle

The treated of Basle of the September 22nd 1499 mark the independence of the Swiss Confederation with respect to the Holy Germanic Roman Empire and the end of the Wars of Souabe. It marks also de facto the independence of the States of the Italy of the North of the Saint Worsens, except Venice and the Papal States which of it were already independent. The dukes of Savoy will however continue to recognize suzerainty, purely nominal, of the Empire.

After preliminary negotiations with Schaffhouse and an armistice concluded on August 25th, it was signed by the emperor Maximilien Ier and the League of Souabe on the one hand, the bishop of Coire Henri, Confédérés (Ducry) and the rhetic Leagues of the other, thanks to the efforts of Ludovic Sforza, duke of Milan, and its envoy Galeazzo Visconti. At first sight, the treaty did nothing but restore the situation former to the war, except for two articles concerning of the rights of suzerainty: the eight jurisdictions of Prättigau remained in Maximilien; the high jurisdiction of Thurgovie would spend in October 1499 of the town of Constancy to Confederated. The real causes of the war of Souabe, namely the introduction of the common sum of money and the introduction of the court of Empire issued by the Diet of Worms of 1495, are not mentioned in the peace treaty. Maximilien is simply committed there ceasing " all private wars, disgraces, banns, lawsuit or griefs" and to take for referees in the event of litigation the bishops of Constancy or Basle and the Council of Basle, the same clause applying to the League of Souabe. The competence of the court of Empire as a supreme authority is of this fact even denied without it being need to stipulate it expressly. But when well even the decrees of the Diet of Worms and the refusal of Confederated to subject itself to it overlooked, old Swiss historiography saw in the peace of Basle a turning in the relations between the Confederation and the Empire. In 1890 still, Wilhelm Oechsli the interpreter like " recognition by Germany of the independence of Suisse". This opinion is currently disputed. The reports/ratios of deputy the soleurois on the talks of Basle reveal on the contrary the desire, at Confédérés, to be " gracefully réadmis in Empire". Until the 17th century, the cantons expressing their membership of the Empire while being offered for example to provide him troops or funds against the Turks, without the prestige of which he enjoys as protective supreme from Christendom does not suffer at Confédérés their conflicts with the house from Austria nor from their resistance to the " durcissement" progressive (Peter Moraw) of an imperial constitution " souple" at the origin.
