The subsequent attempts at union proved weak and ineffective. The _Bund_, or bond of connection between these states, formed after the Napoleonic period, was of the most shadowy character, its congress being destitute of power or authority. The National Assembly, convened at Frankfurt after the revolution of 1848, with the Archduke John of Austria as administrator of the empire, proved equally powerless. It made a vigorous effort to enforce its authority, but without avail; Prussia refused to be bound by its decisions; and the attitude of opposition assumed by this powerful state soon brought the new attempt at union to an end. In 1886 the war between the two great powers of Germany, in which most of the smaller powers were concerned, led to more decided measures, in the absorption by Prussia of the states above named, the formation of a North German League among the remaining states of the north, and the offensive and defensive alliance with Prussia of the South German states. By the treaty of peace with Austria, that power was excluded from the German League, and Prussia remained the dominant power in Germany. A constitution for the League was adopted in 1867, providing for a Diet, or legislative council of the League, elected by the direct votes of the people, and an army, which was to be under the command of the Prussian king and subject to the military laws of Prussia. Each state in the League bound itself to supply a specified sum for the support of the army. [=The Feeling for Unity=] Here was a union with a backbone--an army and a budget--and Bismarck had done more in the five years of his ministry in forming an united Germany than his predecessors had done in fifty years. But the idea of union and alliance between kindred states was then widely in the air. Such a union had been practically completed in Italy, and Hungary in 1867 regained her ancient rights, which had been taken from her in 1849, being given a separate government, with Francis Joseph, the emperor of Austria, as its king. It was natural that the common blood of the Germans should lead them to a political confederation, and equally natural that Prussia, which so overshadowed the smaller states in strength, should be the leading element in the alliance. The great increase in the power and importance of Prussia, as an outcome of the war with Austria, was viewed with jealousy in France. The Emperor Napoleon sought, by a secret treaty with Holland, to obtain possession of the state of Luxemburg, for which a sum of money was to be paid. This negotiation became known and was defeated by Bismarck, the King of Holland shrinking from the peril of war and the publicity of a disgraceful transaction. But the interference of Prussia with this underhand scheme added to the irritation of France. [=The Position of Louis Napoleon=]
