Hausen, to the Upper Bavarian Augustinian monastery of Polling near Weilheim. At about the same time, Wilten Abbey (Stift Wilten) was given estates and rights in this area, although its valleys were probably still completely forested at that time. Soon the first farmsteads and farmsteads were built in forest clearings. In 1294, Count Berchtold III of Eschenlohe, who had no children, sold his counties of Mittenwald and Partenkirchen, together with the Wetterstein, to the Bishop of Freising, whose bishopric was thus elevated to a Hochstift. The Hochstift of Freising merged the newly acquired counties with the predium of Garmisch, acquired in 1249, to form the County of Werdenfels. The first description of the border, in 1305, shows that a part of the Leutasch valley belonged to the County of Werdenfels. In 1312, Duke Henry of Carinthia and Count of Tyrol acquired estates in the Leutasch. In 1338, at the head of the valley above the Leutasch Gorge, 300 metres east of the later Leutascher Schanze, he had a castle built, with an outer and inner bailey and a surrounding moat in a square layout. For theirs protection, Tyrol acquired further estates and the Leutasch Valley went to Tyrol in 1500. The subsequent settlement of the Leutasch Valley was slow but steady: by 1775 about 800 people lived in the valley and the population of Leutasch was recorded as 945 in an official 1826 census. The number of territorial lords also grew over the course of time to include the Tyrolean sovereign and Stams Abbey. These territorial lordships were abolished - as in the rest of Austria - in the course of the revolutions of 1848/49. Although the Leutasch valley was off the main communication routes, it was affected by several conflicts: During the Thirty Years' War, Leutasch and the neighbouring community of Seefeld suffered from major looting, while the rest of Tyrol was almost completely spared. During the Bavarian Rummel, the military invasion of Bavarian troops into Tyrol in 1703 in the course of the War of the Spanish Succession, Bavarian troops marched over a mountain path on the Grünkopf - later called the Franzosensteig ("French Path") - and thus bypassed the Tyrolean fortifications of Porta Claudia in the Scharnitz Pass at the start of the Leutasch Valley (the Leutascher Schanz), which protected Tyrol from an invasion from the north via Mittenwald. The Bavarians thus entered Tyrol through Leutasch and
