The castle was built a long time ago in the year 865. Legend says a king built it after seeing an eagle. The eagle perched on a rock as a sign. This is why the fort's name means "Eagles' Teaching." Hasan took over the castle in the year 1090. He did this by winning over the people in the valley first.

Hasan's life was full of travel and study. He was born in the city of Qom in the 1050s. As a young man, he moved to the city of Rayy. He studied many languages and math there. When he was seventeen, he joined the Isma'ili movement. He traveled for two years to reach Cairo in Egypt. He arrived in Cairo on August 30, 1078. During his travels, he went to places like Iraq and Syria. He even visited Armenia and Azerbaijan.

Many people remember Hasan by a special name. The traveler Marco Polo called him the "Old Man of the Mountain." This name came from his mountain home. Hasan's group had many followers called fida'i. These were people who were very devoted to their cause. Hasan's followers had great libraries at the castle. They kept books on science and religion there. He also made a big change for his group. He decided they should use the Persian language for their holy books. This helped their ideas spread through many lands.

He spent most of that time reading, writing, and praying.

Hasan-i Sabbah was a significant religious and military leader in the 11th and 12th centuries.

He founded the Nizari Isma'ili state and the Nizari Isma'ili sect. This group is often known in Western history as the Order of Assassins. Hasan ruled from his mountain stronghold from 1090 to 1124 AD. Beyond his leadership, he was a highly educated scholar. He studied mathematics, specifically geometry, and astronomy. He also explored philosophy and epistemology, which is the study of how we know things. His intellectual depth made him a central figure in the Persian world.

Hasan's early life began in the city of Qom, Persia, during the 1050s. His family was part of the Twelver Shia community. His father was a Kufan Arab who had migrated from Iraq to Qom. Later, the family moved to the city of Rayy. Rayy was a major center for radical Islamic thought and religious study. In Rayy, Hasan mastered several subjects, including languages and palmistry. He also studied the complex principles of philosophy and mathematics. This rigorous education prepared him for his future roles as both a scholar and a leader.

At age 17, Hasan underwent a major religious conversion. He swore allegiance to the Fatimid caliph in Cairo. This commitment led him on a long journey to Egypt. He began his travels in 1076 and spent two years moving through various regions. He visited Isfahan, where he was hosted by a former teacher named Resi Abufasl. His route took him through Arran, which is modern-day Azerbaijan, and Armenia. During his time in Armenia, he was expelled from a town following a heated religious discussion. He eventually reached Damascus and then Palestine before arriving in Egypt on August 30, 1078.

Hasan's time in Cairo was marked by both intense study and political tension. He became a full missionary, but he also encountered opposition. He supported Nizar, the elder son of the Imam-Caliph al-Mustansir, for the succession. This caused trouble with the Chief of the Army, Badr al-Jamali. Hasan was briefly imprisoned, but he was released after a minaret collapsed in the jail. This event was seen as a positive omen. After being deported, he survived a shipwreck and eventually returned to Persia in 1081. He then spent his time traveling and preaching throughout the Persian lands.

In 1088, Hasan found the perfect base for his mission: Alamut Castle.

The castle sits in the Rudbar area of the Alborz mountains. It overlooks a valley roughly 50 kilometers long and 5 kilometers wide. The fortress was originally built around the year 865. Legend says a king named Wah Sudan ibn Marzuban built it after seeing an eagle perch on a rock. He named the fort Aluh Amu(kh)t, meaning "Eagles' Teaching." Hasan took control of the castle in 1090 through a patient, two-year strategy. He first won over the local villagers before infiltrating the fort with his converts.

Hasan's leadership at Alamut was characterized by both scholarship and strict devotion. He was known for his austere lifestyle, which meant living very simply. He spent much of his 35-year residence in the castle reading, writing, and praying. He was a polymath, meaning he was an expert in many different fields. He knew the Qur'an by heart and understood many different Muslim texts. He also studied alchemy, medicine, architecture, and various scientific disciplines. One major change he made was declaring Persian the language for Nizari holy literature. This decision ensured that Nizari texts were written in Persian for centuries.

Outside of Persia, Hasan and his followers became famous through travelers like Marco Polo. Polo referred to the leaders of the sect as the "Old Man of the Mountain." He described their court as a place where young men learned languages, etiquette, and martial skills. The castle also held impressive libraries filled with scientific and religious books. The Nizari doctrine included the idea of a hidden imam who provides spiritual guidance. The followers, known as fida'i, were individuals who offered their lives to their cause. This intense devotion was a core part of the Nizari identity during Hasan's rule.

Hasan's legacy continues to influence history and popular culture. His life has been the subject of many books and stories. For example, the novel *Alamut* by Vladimir Bartol was published in 1938. In 1977, the British rock group Hawkwind even released a song titled "Hassan I Sahba." His followers once called him "Sayyidna," which means "Our Master." Although his mausoleum in Rudbar was later demolished by the Mongols, his impact on Persian history remains. He remains a complex figure who blended deep scientific knowledge with powerful religious leadership.
