クレメンス・フォン・メッテルニヒ
After 1815 Austria's policy as set by Klemens von Metternich was based on a realistic acceptance of Russia's political predominance in Moldavia and Wallachia. He obtained from Tsar Nicholas I some economic concessions during the 1830s. The two powers began to co-operate, with the mutual aim of preserving the status quo.
