Question: What position did the man who defeated the last song emperor of the country Zeng Jize lived in hold?

<P0-S0> Marquis Zeng Jize () (1839 – April 12, 1890), one of China's earliest ministers to London, Paris and Saint Petersburg, played an important role in the diplomacy that preceded and accompanied the Sino-French War (August 1884–April 1885). <SEP> <P1-S0> following the defeat of the usurper known as constantine iii, jovinus was proclaimed emperor at mainz in 411, a puppet supported by gundahar, king of the burgundians, and goar, king of the alans. <P1-S1> jovinus kept his position in gaul for two years, long enough to issue coinage that showed him wearing the imperial diadem. <P1-S2> he was supported by a number of local gallo-roman nobles who had survived constantine's defeat. <SEP> <P2-S0> The Song dynasty is divided into two distinct periods, Northern and Southern. <P2-S1> During the Northern Song (Chinese: 北宋; 960 -- 1127), the Song capital was in the northern city of Bianjing (now Kaifeng) and the dynasty controlled most of what is now Eastern China. <P2-S2> The Southern Song (Chinese: 南宋; 1127 -- 1279) refers to the period after the Song lost control of its northern half to the Jurchen Jin dynasty in the Jin -- Song Wars. <P2-S3> During this time, the Song court retreated south of the Yangtze and established its capital at Lin'an (now Hangzhou). <P2-S4> Although the Song dynasty had lost control of the traditional ``birthplace of Chinese civilization ''along the Yellow River, the Song economy was still strong, as the Southern Song Empire contained a large population and productive agricultural land. <P2-S5> The Southern Song dynasty considerably bolstered its naval strength to defend its waters and land borders and to conduct maritime missions abroad. <P2-S6> To repel the Jin, and later the Mongols, the Song developed revolutionary new military technology augmented by the use of gunpowder. <P2-S7> In 1234, the Jin dynasty was conquered by the Mongols, who took control of northern China, maintaining uneasy relations with the Southern Song. <P2-S8> Möngke Khan, the fourth Great Khan of the Mongol Empire, died in 1259 while besieging the city of Chongqing. <P2-S9> His younger brother Kublai Khan was proclaimed the new Great Khan, though his claim was only partially recognized by the Mongols in the west. <P2-S10> In 1271, Kublai Khan was proclaimed the Emperor of China. <P2-S11> After two decades of sporadic warfare, Kublai Khan's armies conquered the Song dynasty in 1279. <P2-S12> The Mongol invasion led to a reunification under the Yuan dynasty (1271 -- 1368). <SEP> <P3-S0> initially, byrd's label (mca records) had not planned for "the keeper of the stars" to be a single, until his publicist realized that the song had been receiving positive feedback for it in concert. <P3-S1> the fourth single from byrd's "no ordinary man" album, "the keeper of the stars" spent twenty weeks on the "billboard" hot country singles & tracks (now hot country songs) charts, reaching a peak position of number two. <SEP> <P4-S0> Kublai (; ; ) was the fifth Khagan (Great Khan) of the Mongol Empire ("Ikh Mongol Uls"), reigning from 1260 to 1294 (although due to the division of the empire this was a nominal position). <P4-S1> He also founded the Yuan dynasty in China as a conquest dynasty in 1271, and ruled as the first Yuan emperor until his death in 1294.
