Overview
The National Liberal Party (, NlP) was a liberal party of the North German Confederation and the German Empire which flourished between 1867 and 1918.
During the Prussian-led unification of Germany, the National Liberals became the dominant party in the Reichstag. While supporting the common ideals of liberalism and nationalism, the party contained two wings, which reflected the conflicting claims of its Hegelian and idealistic heritage: one emphasized the power of the state through the Nationalstaat, and the other emphasized the civil liberties of the Rechtsstaat. Although that cleavage later proved fatal for its unity, the National Liberals managed to remain the pivotal party in the decades after unification by cooperating with both the Progressives and the Free Conservatives on various issues.
Origins
A first national liberal parliamentary group arose among right-wing deputies of the liberal German Progress Party in the Prussian House of Representatives during a constitutional conflict sparked by Minister President Otto von Bismarck: In 1862, he had overruled the Liberal opposition in parliament using the so-called Lückentheorie ("Gap Theory") to justify proceeding with taxes for military reforms of the Prussian Army, accompanied by his martial "Blood and Iron" speech. In the following years, he aimed to reconcile with his opponents by strengthening Prussian hegemony, which culminated in the Seven Weeks' War of 1866.
