Hasan bin Ali bin Muhammad bin Jafar bin Al Husain bin Muhammad bin Sabah al-Hasan Sabah
AD He was born in 1050 in the Persian city of Com to the family of Twalvarsia. His family moved to Roy in his early days. There he became interested in metaphysical subjects and studied subjects such as language, philosophy and mathematics at home under a teacher.At that time, Ray was one of the pioneers of Ismaili ideas. They were growing up in Persia and the eastern part of Egypt. The Ismailis of Persia did not have to struggle to gain popularity because of their support for the Fatimi Caliphate in Cairo and because the people were dissatisfied with the Saljuq rulers. It was during this time that Hassan Sabah became fascinated with Ismaili's activities and later became a member of it.He later became the father of the Nizari Ismaili Empire and was known as the Old Man of the Mountain during Moroccan polo (a different type of ball game).
The fact that he was able to bring the people of Alborz in the northern mountains of Iran to the concept of Nisari Ismailism in the 11th century is a prime example of his early activism.He then allied himself with Fatimi Khalifa of Cairo at the age of 17. However, he did not want to be involved in Fatima's activities and wanted to continue his studies. However, his small-scale activities and intellect influenced Abul Malik bin Attas and suggested that he go to Cairo for further study.But he did not go to Cairo, but decided to lead some of Fatimi's plans for growth. It was then that Nizamul Mulk, the most accomplished minister in the Seljuk Empire and a fierce enemy of the Fatima, learned of this, and in 1076 he was forced to leave Rye and move to Cairo.He arrived in Cairo in about two years. During that trip, he visited many important cities and countries, including Isfahan. In the meanwhile, he had made all the preparations for the growth of the Fatimids and the fulfillment of its goals.
Sabah devoted his life and study in Cairo to preparing sermons. However, his army chief, Badr al-Jamali, found out that all these speeches were in favor of the Fatimis, and imprisoned and later deported him.
Later his target was persia.His campaign, which focused on the northern part of Persia and the people of Alborz, who were in complete opposition to Turkish rule, was a complete success. But Nizamul Mulk knew all this and used various tactics to capture Sabah. But not only did he fail in all of this, but he later infiltrated the Saljuki and was responsible for the deaths of Nizamul Mulk and his son Thapar, the powerful ruler of the Saljuki empire, Sultan Malik Shah.
