The Visigothic kingdom always stood apart in the history of the early Middle Ages. The Visigoths, the only barbarians who crushed the Western Roman Empire, were able to create a strong state for quite a long time, which avoided the sad fate of the Ostrogothic kingdom and the Vandal power. Having existed for almost three centuries, the Visigothic statehood was destroyed by the Arab invasion of the Iberian Peninsula. Dietrich Claude, in his book “The History of the Visigoths,” shows that the coexistence of two cultures at a certain level is only possible if they do not oppose each other and make mutual concessions in the main spheres of life, thereby demonstrating tolerance and religious tolerance, which are so necessary in our time .
