Swabian War

The Swabian War of 1499 (Alemannic German: Schwoobechrieg; spelling depending on dialect), called Schwabenkrieg or Schweizerkrieg ("Swiss War") in Germany and Engadiner Krieg ("War of the Engadin") in Austria was the last major armed conflict between the Old Swiss Confederacy and the House of Habsburg. What had begun as a local conflict over the control of the Val Müstair and the Umbrail Pass in the Grisons soon got out of hand when both parties called upon their allies for help; the Habsburgs demanding the support of the Swabian League, while the Federation of the Three Leagues of the Grisons turning to the Swiss Eidgenossenschaft. Hostilities quickly spread from the Grisons through the Rhine valley to Lake Constance and even to the Sundgau in southern Alsace, the westernmost part of the Habsburg region of Further Austria.

Many battles were fought from January to July 1499, and in all but a few minor skirmishes, the experienced Swiss soldiers defeated the Swabian and Habsburg armies. After their victories in the Burgundian Wars, the Swiss had battle tested troops and commanders. On the Swabian side, distrust between the knights and their foot soldiers, disagreements amongst the military leadership, and a general reluctance to fight a war that even the Swabian counts considered to be more in the interests of the powerful Habsburgs than in the interest of the Holy Roman Empire proved fatal handicaps. When his military high commander fell in the battle of Dornach, where the Swiss won a final decisive victory, Emperor Maximilian I had no choice but to agree to a peace treaty signed on September 22, 1499, in Basel. The treaty granted the Confederacy far-reaching independence from the empire. Although the Eidgenossenschaft officially remained a part of the empire until the Treaty of Westphalia in 1648, the peace of Basel exempted it from the imperial jurisdiction and imperial taxes and thus de facto acknowledged it as a separate political entity.

One source of conflict was the ancient distrust, rivalry, and hostility between the Old Swiss Confederacy and the House of Habsburg, which had risen to the throne of the Holy Roman Emperor since 1438. Since the late 13th century, the members of the Swiss Confederacy had gradually taken control of territories that once had belonged to the Habsburg realm. The Swiss had attained the status of imperial immediacy, being subject only to the emperor himself, and not to any intermediate Princes or liege lords. This status granted them a far-reaching autonomy within the Holy Roman Empire, even more so as the emperor was a distant overlord. Before 1438, the empire and the emperor had been an antipole to the Habsburg dukes for the Swiss. Previous emperors had repeatedly supported the confederates in their struggles against the Habsburgs, whom they saw as strong rivals. They had confirmed the Imperial immediacy of the Swiss on several occasions; and the Swiss had succeeded in defending their privileged status against Habsburg dukes who had tried to regain their former territories.^{[citation needed]}

When Frederick III of Habsburg ascended to the throne, the Swiss suddenly faced a new situation in which they could no longer count on support from the empire. Worse yet, conflicts with the Habsburg dukes threatened to become conflicts with the empire itself. Under Frederick's reign, this did not occur yet. Frederick had sided in 1442 against the confederacy in the Old Zürich War where he had supported the city of Zürich, and he also refused to reconfirm the imperial immediacy of the members of the Confederacy. But Frederick's troubled reign did not leave room for military operations against the Swiss. In Austria, Frederick was in conflict first with his brother Albert and then faced the pressure of Matthias Corvinus, who even drove him from Vienna and forced Frederick's court to assume an itinerant lifestyle.

In the empire, Frederick faced the opposition of the Bavarian Wittelsbach dynasty and of his cousin Sigismund, who was duke in Tyrol, Vorarlberg, and Further Austria then. Sigismund had been in conflict with the Swiss Confederacy, too. When he had been banned by Pope Pius II in a conflict over the nomination of a bishop in Tyrol, the Swiss had annexed the formerly Habsburg territories of the Thurgau. In 1468, Sigismund clashed with the Swiss in the War of Waldshut, which he could end without significant territorial losses only by paying a large ransom, which he financed by pawning territories in the Sundgau and the Alsace to Charles the Bold of Burgundy in 1469. Charles did not, however, help Sigismund against the Swiss, and so Sigismund bought back the territories in 1474 and concluded a peace treaty with the Confederacy, the Ewige Richtung, although the emperor never recognized it. In the following Burgundy Wars, the Swiss and Sigismund both fought against Charles the Bold.^{[citation needed]}

In 1487, Sigismund arranged the marriage of Frederick's daughter Kunigunde to Duke Albert IV of Bavaria against her father's will, and he also signed away some of his territories in Tyrol and Further Austria to Albert IV. Frederick intervened by force: he founded the Swabian League in 1488, an alliance of the Swabian cities, the Swabian knights of the League of St. George's Shield and the counts of Württemberg and Tyrol and Vorarlberg. With their help, he forced the Wittelsbach house to return the territories signed over by Sigismund.

In 1490, Sigismund was forced to abdicate and turn over all his territories to Frederick's son Maximilian I. Maximilian had married Mary of Burgundy in 1477 after the death of Charles the Bold in the Burgundy Wars and thus inherited the Burgundian territories: the Duchy of Burgundy, the County of Burgundy (Franche-Comté) and the Netherlands. He took over and expanded the Burgundian administration with a more centralized style of government, which in 1482, caused the outbreak of a rebellion of the cities and counts, allied with Charles VIII of France, against Maximilian. The Duchy of Burgundy was also a French fiefdom and immediately claimed by Charles VIII. The first phase of this conflict would last until 1489, keeping Maximilian occupied in the Low Countries. He even fell into the hands of his enemies and was held prisoner for four months in Bruges in 1488. He was freed only when his father sent an army under the command of Duke Albert of Saxony to his rescue. Maximilian subsequently returned to Germany, leaving his cousin Albert as his representative. Albert would, in the following years, manage to assert the Habsburg hegemony in the Netherlands.

Maximilian had been elected King of the Romans in 1486 on his father's initiative, and they had been ruling jointly since then. Upon the death of Frederick in 1493, Maximilian also took over his father's possessions and thus united the whole Habsburg territory in his hands. In the same year, the Peace of Senlis also marked the end of his wars against the French about his Burgundian possessions; he kept the territories in the Netherlands and also the County of Burgundy, but had to cede the Duchy of Burgundy to the French king. Maximilian controlled thus territories that nearly encircled the Old Swiss Confederacy: Tyrol and Vorarlberg in the east, Further Austria in the north, and the County of Burgundy in the west.^{[citation needed]}
