Given the question: Information: - Boran ( Middle Persian : ; 590 -- 628 or 631 ) was the daughter of the Sasanian emperor Khosrau II. She was the first and one of only two women on the throne of the Sasanian Empire ( the other was her sister and successor Azarmidokht ) . Various authors place her reign between one year and four months to two years . Her name appears as Brn ( or Burn ) on her coinage . The Persian poet Ferdowsi refers to her as Porandokht in his epic poem , the Shahnameh . She was committed to revive the memory and prestige of her father , during whose reign the Sasanian Empire had grown to its largest territorial extent . - Middle Persian is the Middle Iranian language or ethnolect of southwestern Iran that during the Sasanian Empire (224654) became a prestige dialect and so came to be spoken in other regions of the empire as well. Middle Persian is classified as a Western Iranian language. It descends from Old Persian and is the linguistic ancestor of Modern Persian. - The Old Persian language is one of the two directly attested Old Iranian languages (the other being Avestan). Old Persian appears primarily in the inscriptions, clay tablets, and seals of the Achaemenid era (c. 600 BCE to 300BCE). Examples of Old Persian have been found in what is now present-day Iran, Romania (Gherla), Armenia, Bahrain, Iraq, Turkey and Egypt, the most important attestation by far being the contents of the Behistun Inscription (dated to 525 BCE). Recent research into the vast Persepolis Fortification Archive at the Oriental Institute at the University of Chicago have unearthed Old Persian tablets (2007). This new text shows that the Old Persian language was a written language in use for practical recording and not only for royal display. - The Parthian Empire (247BC 224AD), also known as the Arsacid Empire, was a major Iranian political and cultural power in ancient Iran and Iraq. Its latter name comes from Arsaces I of Parthia who, as leader of the Parni tribe, founded it in the mid-3rd century BC when he conquered the region of Parthia in Iran's northeast, then a satrapy (province) in rebellion against the Seleucid Empire. Mithridates I of Parthia (r."c".171138BC) greatly expanded the empire by seizing Media and Mesopotamia from the Seleucids. At its height, the Parthian Empire stretched from the northern reaches of the Euphrates, in what is now central-eastern Turkey, to eastern Iran. The empire, located on the Silk Road trade route between the Roman Empire in the Mediterranean Basin and the Han Empire of China, became a center of trade and commerce. - Persian Empire refers to any of a series of imperial dynasties centered in Persia (modernday Iran). The first of these was the Achaemenid Empire established by Cyrus the Great in 550 BC with the conquest of Median, Lydian and Babylonian empires. It covered much of the Ancient world when it was conquered by Alexander the Great. Several later dynasties "claimed to be heirs of the Achaemenids". Persia was then ruled by the Parthian Empire which supplanted the Hellenistic Seleucid Empire, and then by the Sassanian Empire which ruled up until mid 7th century. - Azarmidokht (Middle Persian: zarmgdukht) was Sasanian queen of Persia from to 630 to 631, and daughter of Khosrow II. She ruled Persia after her cousin Shapur-i Shahrvaraz. - Iran (, also , ; ' ), also known as Persia, officially the Islamic Republic of Iran (' ), is a sovereign state in Western Asia.

Comprising a land area of , it is the second-largest country in the Middle East and the 18th-largest in the world. With 82.8 million inhabitants, Iran is the world's 17th-most-populous country. It is the only country with both a Caspian Sea and an Indian Ocean coastline. The country's central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, make it of great geostrategic importance. Tehran is the country's capital and largest city, as well as its leading economic center. - Islam (' ;) is a religion articulated by the Quran, a text considered by its adherents to be the verbatim word of God ('), and, for the vast majority of adherents, the teachings and normative example (called the "sunnah", composed of accounts called "hadith") of Muhammad (5708 June 632 CE). It is the world's second-largest religion and the fastest-growing major religion in the world, with over 1.7 billion followers or 23% of the global population, known as Muslims. Islam is an Abrahamic monotheistic religion that upholds that God is one and incomparable and that the purpose of existence is to worship God.

It was the political and cultural base of the Arsacid dynasty, rulers of the Parthian Empire (247 BC 224 AD). - The Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire in the East during Late Antiquity and the Middle Ages, when its capital city was Constantinople (modern-day Istanbul, which had been founded as Byzantium). It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, cultural, and military force in Europe. Both "Byzantine Empire" and "Eastern Roman Empire" are historiographical terms created after the end of the realm; its citizens continued to refer to their empire as the "Roman Empire" (tr. ), or "Romania", and to themselves as "Romans". - The Sasanian Empire (or ), also known as Sassanian, Sasanid, Sassanid or Neo-Persian Empire), known to its inhabitants as rnshahr in Middle Persian, was the last imperial dynasty in Persia (Iran) before the rise of Islam, ruled by and named after the Sasanian dynasty from 224 to 651 AD.
