Rückversicherungsvertrag
In 1887, German and Russian alignment was secured by means of a secret Reinsurance Treaty arranged by Otto von Bismarck. However, in 1890, Bismarck fell from power, and the treaty was allowed to lapse in favor of the Dual Alliance (1879) between Germany and Austria-Hungary. That development was attributed to Count Leo von Caprivi, the Prussian general who replaced Bismarck as chancellor. It is claimed that Caprivi recognized a personal inability to manage the European system as his predecessor had and so was counseled by contemporary figures such as Friedrich von Holstein to follow a more logical approach, as opposed to Bismarck's complex and even duplicitous strategy. Thus, the treaty with Austria-Hungary was concluded despite the Russian willingness to amend the Reinsurance Treaty and to sacrifice a provision referred to as the "very secret additions" that concerned the Turkish Straits.
