And here the Albigensian Crusade is very instructive. I tried to show how this conflict, at first religious, turned into a national war. Nation is not predetermined, as is often thought, geography. In no decree of Providence is not provided, that the kingdom of France should extend to the Pyrenees. But they became the boundary of Gaul, and Verdun section included in the South border of the kingdom. However, since the centrifugal forces entered: South saw himself as an autonomous integrity. Undoubtedly, more can not talk about their own national feeling, but elements of it have already been formed. Will be needed, as we shall see, many years to Southerners resigned to the fact that they are only part of a larger community. We can not even say that the day after the statement Mo case was completely resolved. The building, erected in an atmosphere of violence, still extremely fragile. His fate at the mercy of the political situation, which no one could foresee. Now there is another battle with quite different armies. As a result of the increased national feeling more powerful than so painstakingly introduced Catholic orthodoxy, aware of itself.
