Bahíyyih Khánum was the only daughter of Baháʼu'lláh, the founder of the Baháʼí Faith, and Ásíyih Khánum. She was born in 1846 with the given name Fatimih Sultan, and was entitled "Varaqiy-i-'Ulyá" or "Greatest Holy Leaf". Brought up through the trying times her family lived through, in adulthood she served the interests of the religion and was even occasionally trusted with running the affairs of the religion. Greatly favoured by Bahá'u'lláh, she is seen within the Baháʼí Faith as one of the greatest women to have lived. According to Baháʼís, every dispensation has one particular holy woman or "immortal heroine". In the time of Jesus it was the Virgin Mary, the time of Muhammad it was his daughter Fatima Zahra and during the Báb's dispensation it was Táhirih. Baháʼís believe that Bahíyyih Khánum is the outstanding heroine of the Baháʼí dispensation.

Baháʼu'lláh was the founder of the Baháʼí Faith. He was born to an aristocratic family in Persia and was exiled due to his adherence to the messianic Bábí Faith. In 1863, in Iraq, he first announced his claim to a revelation from God and spent the rest of his life in further imprisonment in the Ottoman Empire. His teachings revolved around the principles of unity and religious renewal, ranging from moral and spiritual progress to world governance.
