The first dated evidence of human settlement in the Kaiser Mountains goes back 4000 to 5000 years. These are discoveries of the remains of Stone Age hunters in the Tischofer Cave. Other discoveries have revealed the presence of Bronze Age settlers in the cave. Documentary evidence of human settlement in the Kaisertal in the Middle Ages date back at least to 1430. There is a purchase agreement from that year for a farm called Hinterkaiser. The name Kaiser for the area is older and already appears by 1240 in a Kitzbühel directory of goods which speaks of a Gamsgiayt an dem Chaiser. In 1611 there is an annotation to a picture in the maps of Matthias Burgklehner that states There is in the dominion of Kufstein the Kayser, a very high mountain range, which is just like an imperial crown, on account of its many peaks, and also because it appears from an altitude and miles away as if it is round and crowned. (original: Es ist in der Herrschaft Khueffstein der Kayser, ein sehr hoches Gepürg, so einer kaiserlichen Cron gleich ist, seiner vilfeltigen Zinggen halber, dann auch, dass er in der Heche vil Meils Wegs weit, als ob er rund und gekrönt ware, gesehen wird.)
