The Western Xia Dynasty (Chinese: 西夏; pinyin: Xī Xià; Wade-Giles: Hsi Hsia; literally "Western Xia") or the Tangut Empire, was known to the Tanguts and the Tibetans as Minyak.

The state existed from 1038 to 1227 AD in what are now the northwestern Chinese provinces of Ningxia, Gansu, eastern Qinghai, northern Shaanxi, northeastern Xinjiang, southwest Inner Mongolia, and southernmost Outer Mongolia, measuring about eight hundred thousand square kilometers. The state suffered from devastating destruction by the Mongols who founded Yuan Dynasty (1271–1368), including most of its written records and architecture. Its founders and history therefore remained controversial until recent research conducted both in the West and within China. They occupied the area of important trade route between North China and Central Asia, the Hexi Corridor. The Western Xia made significant achievements in literature, art, music, and architecture, which was characterized as "shining and sparkling". Their extensive stance among the other empires of the Liao, Song, and Jin was attributable to their effective military organizations that integrated cavalry, chariots, archery, shields, artillery (cannons carried on the back of camels), and amphibious troops for combats on land and water.

Genghis Khan (/ˈɡɛŋɡɪs ˈkɑːn/ or /ˈdʒɛŋɡɪs ˈkɑːn/,Mongol: [tʃiŋɡɪs xaːŋ] ( listen); 1162? – August 1227), born Temujin, was the founder and Great Khan (emperor) of the Mongol Empire, which became the largest contiguous empire in history after his death.

He came to power by uniting many of the nomadic tribes of northeast Asia. After founding the Mongol Empire and being proclaimed "Genghis Khan", he started the Mongol invasions that resulted in the conquest of most of Eurasia. These included raids or invasions of the Kara-Khitan Khanate, Caucasus, Khwarezmid Empire, Western Xia and Jin dynasties. These campaigns were often accompanied by wholesale massacres of the civilian populations – especially in Khwarezmia. By the end of his life, the Mongol Empire occupied a substantial portion of Central Asia and China.

Before Genghis Khan died, he assigned Ögedei Khan as his successor and split his empire into khanates among his sons and grandsons. He died in 1227 after defeating the Western Xia. He was buried in an unmarked grave somewhere in Mongolia at an unknown location. His descendants went on to stretch the Mongol Empire across most of Eurasia by conquering or creating vassal states out of all of modern-day China, Korea, the Caucasus, Central Asian countries, and substantial portions of modern Eastern Europe, Russia and the Middle East. Many of these invasions resulted in the large-scale slaughter of local populations, which have given Genghis Khan and his empire a fearsome reputation in local histories.
