A recent social media post by "Mor Edge Insight" has ignited discussion regarding the profound historical contributions stemming from ancient Iran, particularly those attributed to Zoroastrian roots. The tweet asserts that "Almost everything that has come out of Iran over the past 3 millennia that has any real world scientific or technological or geographic significance and value comes from Zoroastrian roots." It further claims that "Even algebra which is wrongly credited to Islam has Zoroastrian origins," and highlights Zoroastrianism as "one of the oldest, if not the oldest, monotheistic religions," noting that "Islam almost wiped it out entirely."
Zoroastrianism, founded by the prophet Zoroaster in ancient Persia, is indeed recognized as one of the world's oldest monotheistic religions, with scholars suggesting its origins as early as 1500-1000 BCE. This ancient faith, centered on the struggle between good and evil and the worship of Ahura Mazda, significantly influenced the development of concepts like heaven, hell, and judgment day in later Abrahamic religions, as noted by the BBC.
Ancient Iran, during periods when Zoroastrianism was the dominant faith, made numerous advancements. These contributions include the establishment of the Royal Road and the world's first formal postal system under the Achaemenid Empire, as detailed by World History Encyclopedia. Early medical knowledge, such as the use of anesthesia during Caesarean sections, is also referenced in ancient Persian texts like the Shahnameh, suggesting a rich scientific tradition.
However, the claim regarding algebra's Zoroastrian origins requires clarification. The systematic development of algebra as an independent mathematical discipline is widely credited to Muhammad ibn Musa al-Khwarizmi, a Persian mathematician active during the Islamic Golden Age in the 9th century CE. His seminal work, Al-Jabr, introduced methods for solving linear and quadratic equations, giving the field its name. While al-Khwarizmi was of Persian descent, and some historical accounts suggest his forebears may have been Zoroastrian, his groundbreaking contributions occurred within the context of Islamic scholarship in Baghdad.
The tweet accurately reflects the historical impact of the Islamic conquest on Zoroastrianism. Following the 7th-century AD conquest, Zoroastrianism, once the state religion of three Persian dynasties, saw a significant decline in its number of adherents and its status, surviving today as a minority religion primarily in parts of Iran and India.
