In 1879, Germany formed the Dual Alliance with Austria-Hungary, an agreement of mutual military assistance in the case of an attack from Russia, which was not satisfied with the agreement of the Congress of Berlin. The establishment of the Dual Alliance led Russia to take a more conciliatory stance and in 1887, the so-called Reinsurance Treaty was signed between Germany and Russia. In it, the two powers agreed on mutual military support in the case that France attacked Germany or an Austrian attack on Russia. Russia turned its attention eastward to Asia and remained largely inactive in European politics for the next 25 years. In 1882, Italy, seeking supporters for its interests in North Africa against France's colonial policy, joined the Dual Alliance, which became the Triple Alliance. In return for German and Austrian support, Italy committed itself to assisting Germany in the case of a French attack.
