Zubaidah bint Ja'far

Zubaidah bint Ja`far ibn al-Mansur (زبيدة بنت جعفر بن المنصور) (died 26 Jumada I 216 AH / 10 July 831 CE) was the best known of the Abbasid princesses, and the wife and double cousin of Harun al-Rashid. She is particularly remembered for the series of wells, reservoirs and artificial pools that provided water for Muslim pilgrims along the route from Baghdad to Mecca and Medina, which was renamed the Darb Zubaidah  in her honor. The exploits of her and her husband, Harun al-Rashid, form part of the basis for The Thousand and One Nights.

Biography
Zubaidah's birthdate is unknown; it is known that she was at least a year younger than Harun. Her father, Ja'far was a brother of the Abbasid caliph al-Mahdi. Her mother, Salsal, was an elder sister of al-Khayzuran, second and most powerful wife of al-Mahdi, and mother of the future caliphs Musa al-Hadi and Harun al-Rashid.

Zubaidah is a pet name, given by her grandfather, caliph al-Mansur. The name means "little butter ball". Zubaidah's real name at birth was Sukhainah or Amat al-'Aziz". Later, Zubaidah got a kunya, Umm Ja'far (meaning Mother of Ja'far), which reflects her royal lineage as a granddaughter of caliph Abu Ja'far al-Mansur and a wife of caliph Abu Ja'far Harun al-Rashid.

She was the granddaughter of the Abbasid caliph Al-Mansur, through his son Ja'far, and cousin of al-Rashid (c. 763 or 766–809), who she later married (Dhu al-Hijjah 165 AH/July 782 CE). The Abbasid caliph Muhammad al-Amin, who had a double royal lineage, was Zubaidah's son. Her stepson was 'Abdullah al-Ma'mun, who also became a caliph after the civil war with al-Amin.

It is said that Zubaidah's palace 'sounded like a beehive' because she employed one hundred women maids who had memorized the Qur'an.

On her fifth pilgrimage to Mecca she saw that a drought had devastated the population and reduced the Zamzam Well to a trickle of water. She ordered the well to be deepened and spent over 2 million dinars improving the water supply of Makkah and the surrounding province. "This included the construction of an aqueduct from the spring of Hunayn, 95 kilometers to the east, as well as the famed "Spring of Zubayda" on the plain of Arafat, one of the ritual locations on the Hajj. When her engineers cautioned her about the expense, never mind the technical difficulties, she replied that she was determined to carry out the work "were every stroke of a pickax to cost a dinar", according to Ibn Khallikan. "

In 792, Harun had Muhammad receive the oath of allegiance (bay'ah) with the name of al-Amīn ("The Trustworthy"), effectively marking him out as his main heir, while Abdallah was not named second heir, under the name al-Maʾmūn ("The Trusted One") until 799.

She also improved the pilgrim route across nine hundred miles of desert between Kufa and Mecca. The road was paved and cleared of boulders and she assembled water storages at intervals. The water tanks also caught the surplus rainwater from storms that occasionally drowned people.

Ibn Battuta, referring to Zubaidah, states that "every reservoir, pool or well on this road which goes from Mecca to Baghdad is due to her munificient bounty...had it not been for her concern on behalf of this road, it would not be usable by anyone." He specifically mentions the water reservoirs at Birkat al-Marjum and al-Qarurah.

Zubaidah hired a staff of assistants to manage her properties and to act on her behalf in numerous business ventures, independent of Harun. Her private home was also administered in a luxurious manner. Her meals were presented on gold and silver plates instead of the simple leather tray commonly used at the time, and she introduced the fashion trend of wearing sandals stitched with gems. She was also carried on a palanquin made of silver, ebony, and lined with silk.

She built herself a palace with a large carpeted banquet hall supported by pillars made of ivory and gold. Verses of the Qur'an were engraved on the walls in gold letters. The palace was encircled by a garden full of uncommon animals and birds. She had a pet monkey attired as a cavalry soldier and hired 30 servants to attend to the monkey's needs. Zubaidah's visitors, including high-ranking generals, were required to kiss the monkey's hand. In addition, a slew of slave girls followed her everywhere she went and each knew the Qur'an by heart.

She rebuilt Tabriz after a disastrous earthquake in 791.

Her husband, Harun al-Rashid died in March 809 while at Tus. He was succeeded by Muhammad al-Amin. He continued the progressive policies of his father. The first two years of his reign were generally peaceful, however al-Amin tried to remove his half-brother as his heir. Which caused civil war. Her son was killed by al-Ma'mun's supporters in 813 and her son was succeeded by al-Ma'mun. Her stepson (also adopted son of Zubaidah) gave her the same respect and position as her son, al-Amin.

Marriage
She was the first wife Harun al-Rashid. Harun and Zubaidah married in 781–82, at the residence of Muhammad bin Sulayman in Baghdad. She had one son. Muhammad, the future caliph al-Amin, was born in April 787.

Abdallah, the future al-Ma'mun, was born in Baghdad on the night of the 13 to 14 September 786 CE to Harun al-Rashid and his concubine Marajil, from Badghis. On the same night, which later became known as the "night of the three caliphs", his uncle al-Hadi died and was succeeded by al-Ma'mun's father, Harun al-Rashid, as ruler of the Abbasid Caliphate. Marajil died soon after his birth, and Abdallah was raised by Harun's wife, Zubaidah.

Death
Zubaidah died in 831, during the reign of her stepson al-Ma'mun.
