The Battle of Ain Jalut (or Ayn Jalut, in Arabic: عين جالوت, the "Spring of Goliath") took place on 3 September 1260 between Mamluks and the Mongols in the southeastern Galilee, in the Jezreel Valley, not far from Zir'in. The battle marked the high-water point of Mongol conquests, and was the first time a Mongol advance had ever been permanently beaten back in direct combat on the battlefield.

After previous battlefield defeats, the Mongols had always returned and avenged their loss, ultimately defeating their enemies. The Battle of Ain Jalut marked the first time they were unable to do so. The Mongol Ilkhanate leader Hulagu Khan was not able to advance into Egypt, and the Khanate he established in Persia was only able to defeat the Mamluks once in subsequent expeditions, briefly reoccupying Syria and parts of Galilee for a few months in 1300.

When Möngke Khan became Great Khan in 1251, he immediately set out to implement his grandfather Genghis Khan's plan for world empire. To lead the task of subduing the nations of the West, he selected his brother, another of Genghis Khan's grandsons, Hulagu Khan.

Ain (French pronunciation: [ɛ̃]; Arpitan: En) is a department named after the Ain River on the eastern edge of France. Being part of the region Rhône-Alpes and bordered by the rivers Saône and Rhône, the department of Ain enjoys a privileged geographic situation. It has an excellent transport network (TGV, highways) and benefits from the proximity to the international airports of Lyon and Geneva.

Ain is composed of four geographically different areas (Bresse, Dombes, Bugey and Pays de Gex) which – each with its own characteristics – contribute to the diversity and the dynamic economic development of the department. In the Bresse agriculture and agro-industry are dominated by the cultivation of cereals, cattle breeding, milk and cheese production as well as poultry farming. In the Dombes, pisciculture assumes greater importance as does viticulture in the Bugey. The high diversification of the department's industry is accompanied by a strong presence of the plastics sector in and around Oyonnax (so-called "Plastics Valley").

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.
