Kilij Arslan I was the Sultan of Rûm during a very transformative era. He ruled the Sultanate from 1092 until his death in 1107. His name, which means "Sword Lion," reflects his role as a military leader. He was the first Turkish and Muslim commander to fight against the Crusaders. These were large groups of soldiers traveling from Western Europe. His reign was defined by his efforts to establish independent rule and defend his lands.

Kilij Arslan's path to leadership began with significant political difficulty. His father, Suleiman ibn Qutalmish, died in 1086. Following this death, Kilij Arslan became a hostage of Sultan Malik Shah I. He was held in Isfahan until the Sultan died in 1092. After a quarrel among his jailers, Kilij Arslan was released. He then marched with the Turkish Oghuz Yiva tribe army. He established his capital at Nicaea, replacing the governor appointed by the previous Sultan.

During this time, the Seljuk Empire was changing rapidly. After Malik Shah I died, many different groups began competing for power. These groups included the Danishmends, the Mangujekids, and the Saltuqids. Other groups like the Artuqids and the Akhlat-Shahs also sought independence. To help manage these political tensions, Kilij Arslan married Ayşe Hatun. She was the daughter of Emir Tzachas. This marriage was an attempt to create an alliance against the Byzantine Empire. They had four sons: Malik Shah, Mesud I, Arab, and Toghrul.

In 1096, the People's Crusade arrived at Nicaea. This group was led by Peter the Hermit and Walter the Penniless. They captured a fort called Xerigordon, which was a four-day march from the capital. Kilij Arslan sent a force to starve the Crusaders out of the fort. He also used spies to trick the Crusaders into an ambush. Later, near the village of Civetot, his army met a large group of unarmed civilians. In this encounter, approximately 17,000 out of 20,000 Christians died.

In May 1097, the main First Crusade began to pose a much larger threat. This army was led by various nobles from Western Europe. Because Kilij Arslan was busy fighting the Danishmends, he was away from Nicaea when the Crusaders arrived. They besieged his capital and defeated him in battle on May 21. The city surrendered to the Byzantines. During this conflict, the Crusaders captured his wife and children.

His wife was sent to Constantinople, but she was eventually returned to him without a ransom due to his relationship with Alexios I Komnenos.

Kilij Arslan did not stop fighting after the loss of Nicaea. He used guerrilla warfare and hit-and-run tactics to harass the Crusader army. He also tried to destroy crops and water sources to stop them from collecting supplies. In June 1101, he and the Danishmends attempted an ambush near Dorylaeum. Although his horse archers could not break the Crusader knight lines, the battle earned him respect. The Gesta Francorum stated that if the Turks had been Christian, they would be the finest of all races.

He found significant success during the Crusade of 1101. He defeated a Crusader force at the Battle of Mersivan. He also won a major victory at Heraclea Cybistra. This victory was important because it proved that Crusader knights were not invincible. Following these successes, he moved his capital to Konya. He also successfully defended the city against forces led by William II of Nevers.

In his final years, Kilij Arslan moved toward the east. He conquered territories such as Harran, Diyarbakr, and Mosul. However, he was eventually defeated at the Khabur River by Muhammad I Tapar. While trying to escape across the river, Kilij Arslan drowned. In January 2021, archaeologists led by Professor Ahmet Tanyıldız discovered his grave. They found the site of his and his daughter Saide Hatun's graves in Silvan, Diyarbakır. The researchers dug two metres deep across a 35-square-metre area in Orta Çeşme Park.
