Racconigi Bargain

The Racconigi Bargain was a secret agreement between King Victor Emmanuel III of Italy and Tsar Nicholas II of the Russian Empire, concluded on 24 October 1909 at the Castle of Racconigi, in Italy.
Its terms included:

If Russia or Italy concluded agreements concerning Eastern Europe with another power, the other party of the agreement would also participate in such new agreement.
Italy recognised that Russian interests in the Turkish Straits should be controlled by Russia. In return, Russia recognised Italian interests in Tripoli and Cyrenaica.

From Italy's point of view, the Racconigi Bargain facilitated Italy's preparations for the Italo-Turkish War two years later during which Italy conquered Tripoli and Cyrenaica.
