Hulagu Khan in the context of "Ariq Böke"

Mongol invasions of Anatolia occurred at various times, starting with the campaign of 1241–1243 that culminated in the Battle of Köse Dağ. Real power over Anatolia was exercised by the Mongols after the Seljuks surrendered in 1243 until the fall of the Ilkhanate in 1335. Because the Seljuk sultan rebelled several times, in 1255, the Mongols swept through central and eastern Anatolia. An Ilkhanate garrison was stationed near Ankara. Remains of the Mongol cultural heritage still can be seen in Turkey, including tombs of a Mongol governor and a son of Hulagu.

By the end of the 14th century, most of Anatolia was controlled by various Anatolian beyliks due to the collapse of the Seljuk dynasty in Rum. The Turkmen beyliks were under the control of the Mongols through declining Seljuk sultans. The Beyliks did not mint coins in the names of their own leaders while they remained under the suzerainty of the Ilkhanids. The Ottoman ruler Osman I was the first Turkish ruler who minted coins in his own name in the 1320s. Since the minting of coins was a prerogative accorded in Islamic practice only to be a sovereign, it can be considered that the Ottomans became independent of the Mongol Khans.

The 13th century was the century which lasted from January 1, 1201 (represented by the Roman numerals MCCI) through December 31, 1300 (MCCC) in accordance with the Julian calendar.

The Mongol Empire was founded by Genghis Khan, which stretched from Eastern Asia to Eastern Europe. The conquests of Hulagu Khan and other Mongol invasions changed the course of the Muslim world, most notably the Siege of Baghdad (1258) and the destruction of the House of Wisdom. Other Muslim powers such as the Mali Empire and Delhi Sultanate conquered large parts of West Africa and the Indian subcontinent, while Buddhism witnessed a decline through the conquest led by Bakhtiyar Khilji. The earliest Islamic states in Southeast Asia formed during this century, most notably Samudera Pasai. The Kingdoms of Sukhothai and Hanthawaddy would emerge and go on to dominate their surrounding territories.

The Mongol campaign against the Nizaris of the Alamut period (the Nizari Ismaili state) began in 1253 after the Mongol invasion of the Khwarazmian Empire and a series of Nizari–Mongol conflicts. The campaign was ordered by the Great Khan Möngke and was led by his brother, Hülegü. The campaign against the Nizaris and later the Abbasid Caliphate was intended to establish a new khanate in the region—the Ilkhanate.

Hülegü's campaign began with attacks on strongholds in Quhistan and Qumis amidst intensified internal dissensions among Nizari leaders under Imam Muhammad III of Alamut whose policy was fighting against the Mongols. His successor, Rukn al-Din Khurshah, began a long series of negotiations in face of the implacable Mongol advance. In 1256, the Imam capitulated while besieged in Maymun-Diz and ordered his followers to do likewise according to his agreement with Hülegü. Despite being difficult to capture, Alamut ceased hostilities too and was dismantled. The Nizari state was thus disestablished, although several individual forts, notably Lambsar, Gerdkuh, and those in Syria continued to resist. Möngke Khan later ordered a general massacre of all Nizaris, including Khurshah and his family.

Baiju Noyan or Baichu (Mongolian: ᠪᠠᠶᠢᠵᠤ ᠨᠣᠶᠠᠨ; Chagatai: بایجو نویان; Chinese: 拜住; pinyin: Bàizhù; in European sources: Bayothnoy; fl. died c. 1258) was a Mongol commander in Persia, Armenia, Anatolia and Georgia. He was appointed by Ögedei Khan to succeed Chormagan. He was the last direct imperial governor of the Mongol Near East; after his death Hulagu's descendants inherited domains he once commanded.

Tolui (c. 1191 – 1232) was the youngest son of Genghis Khan and Börte. A prominent general during the early Mongol conquests, Tolui was a leading candidate to succeed his father after his death in 1227 and ultimately served as regent of the Mongol Empire until the accession of his brother Ögedei two years later. Tolui's wife was Sorghaghtani Beki; their sons included Möngke and Kublai, the fourth and fifth khans of the empire, and Hulagu, the founder of the Ilkhanate.

Tolui was less active than his elder brothers Jochi, Chagatai, and Ögedei during their father's rise to power, but once he reached adulthood he was considered the finest warrior of the four. He commanded armies under his father during the first invasion of Jin China (1211–1215), and his distinguished service during the Mongol invasion of the Khwarazmian Empire secured his reputation. After the fall of the cities of Transoxiana in 1220, Genghis dispatched Tolui early the following year to subjugate the region of Khorasan, which had begun to cause trouble for the Mongol armies. Tolui executed his orders with ruthless efficiency, assaulting the major cities of Merv, Nishapur, and Herat, and subjugating numerous others. Medieval chroniclers attributed more than three million deaths to the massacres he ordered at Nishapur and Merv; while these figures are considered exaggerated by modern historians, they are evidence of the abnormal brutality of Tolui's campaign.

Surqaghtani Beki (or simply Bekhi; c. 1190 – 1 March 1252), posthumously Empress Xianyi Zhuangsheng, was a Keraite princess and daughter-in-law of Genghis Khan. Married to Tolui, Genghis' youngest son, Sorghaghtani became one of the most powerful and competent people in the Mongol Empire. She made policy decisions at a pivotal moment that led to the transition of the Mongol Empire towards a more cosmopolitan and sophisticated style of administration. She raised her sons to be leaders and maneuvered the family politics so that all four of her sons, Möngke Khan, Hulagu Khan, Ariq Böke, and Kublai Khan, went on to inherit the legacy of their grandfather.

Given her enormous impact at such a critical point of the mighty Mongol Empire, she is likely one of the most influential and powerful women in history. Sorghaghtani was a Christian, specifically a member of the Church of the East (often misleadingly referred to as "Nestorianism"). As a moving spirit behind the Mongol Empire, Sorghaghtani is responsible for much of the trade openings and intellectual exchange of the largest contiguous empire in world history.

Kitbuqa Noyan (died 1260), also spelled Kitbogha, Kitboga, or Ketbugha, was an Eastern Christian of the Naimans, a group that was subservient to the Mongol Empire. He was a lieutenant and confidant of the Mongol Ilkhan Hulagu, assisting him in his conquests in the Middle East including the sack of Baghdad in 1258. When Hulagu took the bulk of his forces back with him to attend a ceremony in Mongolia, Kitbuqa was left in control of Syria, and was responsible for further Mongol raids southwards towards the Mamluk Sultanate based in Cairo. He was killed in 1260 at the Battle of Ain Jalut, which was the first major loss of the Mongolian advances and halted their expansion into Arabia and Europe.
