Aga Khan in the context of "Fatimah"

The Fatimid dynasty (Arabic: الفاطميون, romanized: al-Fāṭimiyyūn) was an Arab dynasty that ruled the Fatimid Caliphate, between 909 and 1171 CE. Descended from Fatima and Ali, and adhering to Isma'ili Shi'ism, they held the Isma'ili imamate, and were regarded as the rightful leaders of the Muslim community. The line of Nizari Isma'ili imams, represented today by the Aga Khans, claims descent from a branch of the Fatimids. The Alavi Bohras, predominantly based in Vadodara, also claim descent from the Fatimids.

The Fatimid dynasty emerged as the leaders of the clandestine early Isma'ili missionary movement (da'wa) in the ninth century CE, ostensibly acting on behalf of a hidden imam, implied at the time to be Muhammad ibn Isma'il. The Isma'ili da'wa spread widely across the Islamic world, then ruled by the Abbasid Caliphate. In 899, the future first Fatimid caliph, Abdallah, proclaimed himself to be the expected imam, causing a rift in the Isma'ili da'wa as the Qarmatians, who did not recognize his imamate, split off. In the meantime, Isma'ili agents had managed to conquer large parts of Yemen and Ifriqiya, as well as launch uprisings in Syria and Iraq. Fleeing Abbasid persecution to Ifriqiya, Abdallah proclaimed himself openly and established the Fatimid Caliphate in 909. From there, the Fatimid imam–caliphs extended their rule over most of the Maghreb as well as Sicily, before conquering Egypt in 969. Founding Cairo as their new capital, for the next two centuries, the Fatimids would be based in Egypt and identified with the country. At their height, the Fatimids claimed control or suzerainty over much of North Africa, Sicily, Egypt, the Levant, the Hejaz, Yemen, and Multan.

Nizari Isma'ilis (Arabic: النزارية, romanized: al-Nizāriyya) are the largest segment of the Ismailis, who are the second-largest branch of Shia Islam after the Twelvers. Nizari teachings emphasise the independent legal jurisprudence or ijtihad—though they reject legal reasoning, or usul—pluralism (the acceptance of racial, ethnic, cultural and inter-religious differences) and social justice. Nizaris, along with Twelvers, adhere to the Jaʽfari school of jurisprudence. The Aga Khan, currently Aga Khan V, is the spiritual leader and Imam of the Nizaris. The global seat of the Ismaili Imamate is in Lisbon, Portugal.

The official religion of Pakistan is Islam, as enshrined by Article 2 of the Constitution, and is practised by an overwhelming majority of 96.35% of the country's population. The remaining 3.65% practice Hinduism, Christianity, Ahmadiyya (considered a non-Muslim group as per the Pakistani constitution), Sikhism, Zoroastrianism and other religions.

Muslims comprise a number of sects: the majority practice Sunni Islam (estimated at 85-90%), while a minority practice Shia Islam (estimated at 10-15%). Most Pakistani Sunni Muslims belong to the Hanafi school of jurisprudence, which is represented by the Barelvi and Deobandi traditions. However, the Ahl-i Hadith movement has also gained popularity together with Wahhabi influence from the Middle East. The majority of Pakistani Shia Muslims belong to the Twelver Islamic law school, with significant minority groups who practice Ismailism, which is composed of Nizari (Aga Khanis), Mustaali, Dawoodi Bohra, Sulaymani, and others.

A reign is the period of a person's or dynasty's occupation of the office of monarch of a nation (e.g., Saudi Arabia, Belgium, Andorra), of a people (e.g., the Franks, the Zulus) or of a spiritual community (e.g., Catholicism, Tibetan Buddhism, Nizari Ismailism). In most hereditary monarchies and some elective monarchies (e.g., Holy Roman Empire) there have been no limits on the duration of a sovereign's reign or incumbency, nor is there a term of office. Thus, a reign usually lasts until the monarch dies, unless the monarchy itself is abolished or the monarch abdicates or is deposed.

In elective monarchies, there may be a fixed period of time for the duration of the monarch's tenure in office (e.g., Malaysia).

Shah Rahim al-Hussaini (Persian: رحیم الحسینی;‎ born 12 October 1971), known as the Aga Khan V (Persian: آقاخان پنجم, romanized: Āqā Khān Panjum), is a religious leader, philanthropist (through the Aga Khan Development Network), and businessman. He is the 50th hereditary Imam of the Shia Nizari Isma'ili Muslims, a branch of Islam. He is the descendant from Muhammad through his daughter, Fatima, and his cousin and son-in-law, Ali. The Qasimi Nizari Ismailis maintain that they are the only Shi‘i group today led by a living, present, hereditary Imam.

He is the second of four children of Shah Karim al-Husseini, who went by the title Aga Khan IV, and succeeded as the Nizari Imam following his father's death on 4 February 2025. He is the fifth person in the family to hold the title Aga Khan. Upon assuming the Imamate, he inherited his father's estate, which had been valued at over US$13.3 billion by Vanity Fair in 2013.

The Ismaili Centres are symbolic markers of the permanent presence of the Nizari Ismailis in the countries and regions in which they are established, characterised by the Aga Khan IV as 'ambassadorial buildings'. Each building is architecturally unique and functions as a jamatkhana (place of worship), but also incorporates spaces for social and cultural gatherings, intellectual engagement and reflection, as well as spiritual contemplation. They facilitate mutual exchange and seek to foster understanding between diverse peoples, communities and faiths. Collectively and individually, the Centres represent the Nizari Ismaili community’s intellectual and spiritual understanding of Islam, as well as the community’s social conscience, outlook and attitude towards the societies in which it lives.
