The Song Dynasty (Chinese: 宋朝; pinyin: Sòng Cháo; Wade-Giles: Sung Ch'ao; IPA: [sʊ̂ŋ tʂʰɑ̌ʊ̯]) was a ruling dynasty in China between 960 and 1279; it succeeded the Five Dynasties and Ten Kingdoms Period, and was followed by the Yuan Dynasty. It was the first government in world history to issue banknotes or paper money, and the first Chinese government to establish a permanent standing navy. This dynasty also saw the first known use of gunpowder, as well as first discernment of true north using a compass.
The Song Dynasty is divided into two distinct periods: the Northern Song and Southern Song. 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 inner China. The Southern Song (Chinese: 南宋, 1127–1279) refers to the period after the Song lost control of northern China to the Jin Dynasty. During this time, the Song court retreated south of the Yangtze River and established their capital at Lin'an (now Hangzhou). Although the Song Dynasty had lost control of the traditional birthplace of Chinese civilization along the Yellow River, the Song economy was not in ruins, as the Southern Song Empire contained 60 percent of China's population and a majority of the most productive agricultural land. The Southern Song Dynasty considerably bolstered its naval strength to defend its waters and land borders and to conduct maritime missions abroad.
Kublai Khan ( /ˈkuːblə ˈkɑːn/; Mongolian: Хубилай хаан, Xubilaĭ xaan; Middle Mongolian: Qubilai Qaγan, "King Qubilai"; September 23, 1215 – February 18, 1294), born Kublai (Mongolian: Хубилай, Xubilaĭ; Middle Mongolian: Qubilai; Chinese: 忽必烈; pinyin: Hūbìliè; also spelled Khubilai) and also known by the temple name Shizu (Chinese: 元世祖; pinyin: Yuán Shìzǔ; Wade–Giles: Yüan Shih-tsu), was the fifth Great Khan of the Mongol Empire from 1260 to 1294 and the founder of the Yuan Dynasty in China.
As he was the second son of Tolui and Sorghaghtani Beki, and a grandson of Genghis Khan, he claimed the title of Khagan of the Ikh Mongol Uls (Mongol Empire) in 1260 after the death of his older brother Möngke in the previous year, though his younger brother Ariq Böke was also given this title in the Mongolian capital, Karakorum. Kublai won the battle against Ariq Böke in 1264 and the succession war marked the beginning of disunity in the empire. Kublai's real power was limited to China and Mongolia (which was the Yuan Dynasty, or the Mongol Dynasty) after the victory over Ariq Böke, though his influence still remained in the Ilkhanate and, to a far lesser degree, in the Golden Horde in the western parts of the Mongol Empire. If one counts the Mongol Empire at that time as a whole, his realm reached from the Pacific to the Urals, from Siberia to modern day Afghanistan – one fifth of the world's inhabited land area.
