Question: How old was Angela Merkel when Kohl resigned his honorary chairman position at CDU? Passage:As Chancellor Kohl was strongly committed to European integration and French–German cooperation in particular; he was also a steadfast ally of the United States and supported Reagan's more aggressive policies in order to weaken the Soviet Union. Kohl's 16-year tenure was the longest of any German Chancellor since Otto von Bismarck. He oversaw the end of the Cold War and the German reunification, for which he is generally known as Chancellor of Unity. Together with French President François Mitterrand, Kohl was the architect of the Maastricht Treaty, which established the European Union (EU) and the euro currency. Kohl was also a central figure in the eastern enlargement of the European Union, and his government led the effort to push for international recognition of Croatia, Slovenia, and Bosnia and Herzegovina when the states declared independence. He played an instrumental role in solving the Bosnian War. Domestically, Kohl's policies focused on economic reforms and later also on the process of integrating the former East Germany into the reunited Germany, and he moved the federal capital from the "provisional capital" Bonn back to Berlin, although he himself never resided there because the government offices were only relocated in 1999. Kohl also greatly increased federal spending on arts and culture. After his chancellorship, Kohl's reputation suffered domestically because of his role in the CDU donations scandal and he had to resign from his honorary chairmanship of the CDU after little more than a year in January 2000, but he was partly rehabilitated in later years. The later Chancellor Angela Merkel started her political career as Kohl's protegée.

Question: When was the man who was a commander for the Russo-Turkish War born? Passage:In 1625, at Lake Kurukove in Kremenchuk, the Treaty of Kurukove was signed between the Cossacks and the Poles. Since the establishment of Cossack Hetmanate, the city was part of the Chyhyryn Polk (regiment). Following the Russo-Polish War (1654–1667) and Treaty of Andrusovo, the city was secured by Tsardom of Russia and became part of the Myrhorod Polk (regiment) within the left-bank Cossack Hetmanate. The city played a key role of the Russian colonization policy of Ukraine and their strive for the shores of Black Seas as regional administrative center of the early Novorossiya Governorate and Yekaterinoslav Vice-regency (Namestnichestvo). With creation of Novorossiya Governorate, in Kremenchuk was created Dnieper Pikers Regiment and coincidentally few years later (1768–69) in the neighboring regions of Poland started out so called Koliyivshchyna (literally the Piker's unrest). Here in 1786 started his military career the Russian general Alexander Suvorov when he was appointed a commander the local garrison (in preparation of the 1787–1792 Russo-Turkish War).
