"There were many territorial, dynastic, and religious issues that figured in the outbreak and conduct of the war. The extent of religious motives is debated, but cannot be dismissed, particularly in explaining individual behavior. Throughout the war there were shifting alliances and local peace treaties. The war as a whole may be considered a struggle of German Protestant princes and foreign powers (France, Sweden, Denmark, England, the United Provinces) against the unity and power of the Holy Roman Empire as represented by the Hapsburgs , allied with the Catholic princes, and against the Hapsburgs themselves.

    The war began with the resistance and eventual revolt of Protestant nobles in Bohemia, which was under Hapsburg domination, against the Catholic king Ferdinand (later Holy Roman Emperor Ferdinand II ). It spread through Europe because of the constitutional frailty of the Holy Roman Empire, the inability of the German states to act in concert, and the ambitions of other European powers."

Revolt also appeared in other Hapsburg dominions, especially under Gabriel Bethlen in Transylvania. ... severe repression began in Bohemia."

      - "Wallenstein was murdered in 1634 by imperialist conspirators. Soon afterward the imperial forces under Gallas defeated Bernhard at Nördlingen (Feb., 1634). Germany was in economic ruin, her fields devastated and blood-soaked. There was strong feeling in Germany against the foreign soldiers that overran the land. A general desire for peace led to the Peace of Prague (1635). This agreement drastically modified the Edict of Restitution, thus helping to reconcile Catholics and Protestants. It was accepted by almost all the German princes and free cities. A united imperial army was to move against the Swedish troops in Germany. A general peace seemed to be forthcoming, but Richelieu was unwilling to see the Hapsburgs retain power."

"The general results of the war may be said to have been a tremendous decrease in German population; devastation of German agriculture; ruin of German commerce and industry; the breakup of the Holy Roman Empire, which was a mere shell in the succeeding centuries; and the decline of Hapsburg greatness. The war ended the era of conflicts inspired by religious passion, and the Peace of Westphalia was an important step toward religious toleration. The incredible sufferings of the German peasantry were remembered for centuries. The political settlements of the peace were to the disadvantage of Germany as well as the Hapsburgs. The estrangement of N Germany from Austria, then begun, was to continue for more than two centuries."
