Peace of Westphalia
The peace negotiations were held in the cities of Münster and Osnabrück, which lie about 50 km apart from each other, in the present German states of North Rhine-Westphalia and Lower Saxony. Sweden had favoured Osnabrück because of its Protestant background, France chose Münster because of its Catholic background. In any case, two locations were required because the Protestant and Catholic leaders refused to meet each other. The Catholics used Münster, and the Protestants used Osnabrück.
