Boran
Boran (also spelled Buran, Middle Persian: ; New Persian: پوراندخت, "Pūrāndokht") was Sasanian queen (or "banbishn") of Iran from 630 to 632, with an interruption of some months.
She was the daughter of king (or "shah")
Khosrow II  and the Byzantine princess Maria.
She is the second of only three women to rule in Iranian history, the others being Musa of Parthia, and Boran's sister Azarmidokht.
In 628, her father was overthrown and executed by her brother-husband Kavad II, who also had all Boran's brothers and half-brothers executed, initiating a period of fractionalism within the empire.
Kavad II died some months later, and was succeeded by his eight-year-old son Ardashir III, who after a rule of nigh two years, was killed and usurped by the Iranian military officer Shahrbaraz.
Boran shortly ascended the throne with the aid of the military commander Farrukh Hormizd, who helped her to overthrow Shahrbaraz.
She and her sister were the only legitimate heirs who could rule at the time.
Boran inherited a declining empire that was engulfed in a civil war between two major factions, the Persian ("Parsig") and Parthian ("Pahlav") noble-families.
She was committed to reviving the memory and prestige of her father, during whose reign the Sasanian Empire had grown to its largest territorial extent.
She was however not long afterwards replaced by Khosrow II's nephew Shapur-i Shahrvaraz, whose reign was even briefer than hers, being replaced by Azarmidokht, who was a "Parsig" nominee.
She was in turn deposed soon afterwards and killed by the "Pahlav" under Farrukh Hormizd's son Rostam Farrokhzad, who restored Boran to the throne, thus making her queen for a second time.
During her second reign, power was mostly in the hands of Rostam, which caused dissatisfaction among the "Parsig" and led to a revolt, during which Boran was killed by strangulation.
She was succeeded by her nephew Yazdegerd III, the last Sasanian ruler, making her the penultimate ruler of the Sasanian Empire.
Albeit her two tenures of rule were shortlived, she did try to bring stability to Iran by the implementation of justice laws, reconstruction of the infrastructure, and by lowering taxes and minting coins.
Diplomatic wise, she desired good relations with her western neighbours–the Byzantines, whom she had an embassy sent to, which was well received by emperor Heraclius (610–641).

Khosrow II
Khosrow II (Chosroes II in classical sources; Middle Persian: "Husrō(y)"), also known as Khosrow Parviz (New Persian: , "Khosrow the Victorious") was the last great Sasanian king (shah) of Iran, ruling from 590 to 628, with an interruption of one year.
He was the son of Hormizd IV (reigned 579–590) and the grandson of Khosrow
I (reigned 531–579).
Khosrow II was the last king of Iran to have a lengthy reign before the Muslim conquest of Iran, which began five years after his execution.
He lost his throne, then recovered it with Roman help, and, a decade later, went on to emulate the feats of the Achaemenids, conquering the rich Roman provinces of the Middle East; much of his reign was spent in wars with the Byzantine Empire and struggling against usurpers such as Bahram Chobin and Vistahm.
During the climactic Byzantine–Sasanian War of 602–628, Khosrow expanded deep into western Asia Minor, eventually besieging the Byzantine capital of Constantinople in 626 alongside Avar and Slavic allies.
Following the failure of the siege, Heraclius started a counterattack, undoing all territorial gains by Khosrow in the Levant, most of Anatolia, the western Caucasus, and Egypt, eventually marching into the Sassanian capital of Ctesiphon.
The Byzantines also regained the True Cross, which Khosrow had captured following his conquest of the Levant during the same 602–628 war.
In works of Persian literature such as the "Shahnameh" and "Khosrow and Shirin", a famous tragic romance by Nizami Ganjavi (1141–1209), a highly elaborated fictional version of Khosrow's life made him one of the greatest heroes of the culture, as much as a lover as a king.
"Khosrow and Shirin" tells the story of his love for the Aramean or Roman princess Shirin, who becomes his queen after a lengthy courtship strewn with mishaps and difficulties.
