In the year 732 the Frankish army, under his commander Charles Martell, fought a decisive battle between Tours and Poitiers against the Muslims, led by Abdarrahman al-Ghafiki, who were on the point of expanding their influence to Merovingian territory. Although the importance of this battle is controversial in modern science, it seems understated to talk of an unimportant raid, knowing, that the Muslim expansion northwards was stopped permanently. The thesis not only informs about the battle itself but also tries to compare and verify the different opinions, leading us to the belief, that the event probably must have taken place in the year 732, in a small village, called Moussais-la-Bataille today, between Tours and Poitiers. Furthermore this thesis shows the different points of view of almost 1300 years of historiography, comparing the oldest sources from the 8th century up to the most recently published works on medieval history and the battle of Poitiers. This part of the thesis makes clear, that the adoption and the related importance changed many times during the last centuries. In the 8th century there was no sign of special importance apart from chronicles influenced by Merovingian and Frankish sovereigns. After the crusades opinions changed and in the following centuries many historians viewed the Frankish victory as an important one and some of them even judged the battle as one of the most decisive battles in universal history. On the other hand, recent studies on the subject tended to see the battle more or less as one episode during a period of major events.The intention of the last part of the thesis was to show and compare different approaches of French and Austrian school books and their reports on the battle of Poitiers. The study concludes that there is no particular difference between the two country?s interpretations and that Charles victory is not given enough attention in history lessons.
