In August, 1794, the reign of terror in France reached its close. The moderate party which came into power gave hopes of a general peace, and Frederick William II without loss of time negotiated a separate treaty, suddenly abandoned the monarchical cause which he had formerly so zealously upheld, and offered his friendship to the revolutionary nation, against which he had so lately hurled a violent manifesto. The French, with equal inconsistency on their part, abandoned the popular cause, and, after having murdered their own sovereign and threatened every European throne with destruction, accepted the alliance of a foreign king. Both parties, notwithstanding the contrariety of their principles and their mutual animosity, were conciliated by their political interest. The French, solely bent upon conquest, cared not for the liberty of other nations; Prussia, intent upon self- aggrandizement, was indifferent to the fate of her brother sovereigns. Peace was concluded between France and Prussia at Basel, April 5, 1795. By a secret article of this treaty, Prussia confirmed the French republic in the possession of the whole of the left bank of the Rhine, while France in return richly indemnified Prussia at the expense of the petty German states. This peace, notwithstanding its manifest disadvantages, was also acceded to by Austria, which, on this occasion, received the unfortunate daughter of Louis XVI. in exchange for Semonville and Maret, the captive ambassadors of the republic, and the members of the Convention seized by Dumouriez. Hanover[3] and Hesse-Cassel participated in the treaty and were included within the line of demarcation, which France, on her side, bound herself not to transgress. The countries lying beyond this line of demarcation, the Netherlands, Holland, and Pfalz-Juliers, were now abandoned to France, and Austria, kept in check on the Upper Rhine, was powerless in their defence. In this manner fell Luxemburg and Düsseldorf. All the Lower Rhenish provinces were systematically plundered by the French under pretext of establishing liberty and equality.[4] The Batavian republic was permitted to subsist, but dependent upon France; Belgium was annexed to France, A.D. 1795.
