  Ibn Mardanish, also known as the Wolf King, was a powerful Muslim king in the Iberian Peninsula in the 12th century. He established his own dominion over the cities of Murcia, Valencia, and Dénia after the decline of the Almoravids. Like the Iberian Christian kings, he opposed the spread of the Almohad caliphate, and his reign shows that the "Reconquista" was not a conflict between two clearly divided factions of Christians and Muslims, but of rival kingdoms of both religions that sometimes faced each other in combat or joined in alliances against each other in various contexts. Ibn Mardanish came from a family originally descended from Visigoths who had converted to Islam. He hired Christian mercenaries from Barcelona, Castile, and Aragon to help him preserve the lands of his kingdom, and signed treaties with the republics of Pisa and Genoa, which had strong bases and commercial relations with his kingdom. His reign was marked by conquests and territorial expansions, and h

  Introducing the Banu Musa brothers, Muhammad, Ahmad, and al-Hasan, three Persian geniuses who received education under al-Ma'mun’s direction, and were enrolled at the House of Wisdom in Baghdad.  The three brothers were commissioned by al-Maʾmūn to measure the length of a degree of latitude and therefrom the circumference of the earth; they carried this task out successfully in the desert plain near Senjār in northern Mesopotamia (Nallino, pp. 420-35). They also made astronomical observations together at Baghdad. They worked together as well as separately: Jafar Muhammad was an expert on mathematics and astronomy, Ahmad excelled in technology, and al-Hasan on mathematics. Muhammed knew the works of both Euclid and Ptolemy, and was considered by contemporaries to be an expert mathematician, astronomer, and philosopher. All but three of the books attributed by scholars to the Banu Musa are now lost. The oldest brother, Moḥammad, was also the most productive, though only one of his

  Astronomy made enormous strides during the Islamic Golden Age (8th–14th centuries CE), when intellectuals made ground-breaking discoveries and inventions. The naming and identifying of stars, with Arabic names such Fomalhaut, Algol, Vega, and Altair still in use today, was one of the most notable contributions. Muslim astronomers created new methods and tools for watching and measuring the skies throughout this time by studying and expanding upon the work of Greek, Indian, and Persian astronomers. The astrolabe, a portable device used to measure the locations of stars and planets, was one of the most crucial tools. The earliest precise solar calendar, which is still employed in some regions of the world today, was created by Muslim astronomers. The naming and identifying of stars by Islamic astronomers may have been their most important contribution. They cataloged and recorded the positions of numerous stars in addition to giving them names. This improved navigational accuracy and c

The Great Mosque of Cordoba, also known as the Mosque-Cathedral of Cordoba, is one of Spain's most recognizable structures and a representation of the rich intellectual and cultural legacy of the Islamic Golden Period. The mosque, which was constructed in the eighth century and later repaired and expanded, was converted into a cathedral after Córdoba was conquered by Christians in the thirteenth century. Its importance as a hub of knowledge and invention throughout the Islamic Golden Period, however, cannot be emphasized. The Mosque-Cathedral served as the epicenter of this intellectual and artistic renaissance in Córdoba, which was at the time a major hub of Islamic learning and cultural success. Al-Zahrawi, a physician and surgeon widely considered as the pioneer of modern surgery, was one of the most significant individuals connected to the mosque. He authored the Al-Tasrif, a significant medical work that was translated into Latin and used as a standard medical reference in Eur

The Battle of Yarmouk was a major historical event that took place in 636 AD. It was fought between the armies of the Muslim Caliphate and the Eastern Roman Empire. The battle is considered to be one of the most significant battles in the history of Islam, as it marked the beginning of the Muslim conquests of the Levant. The battle took place near the Yarmouk River, which is located in modern-day Syria. The Muslim forces were led by Khalid ibn al-Walid, who was one of the most successful military commanders in Islamic history. The Roman forces were led by Heraclius, who was the Emperor of the Eastern Roman Empire. The Muslim army was vastly outnumbered, with only 40,000 soldiers compared to the Roman army's 200,000. However, the Muslim army was highly disciplined and had a strong cavalry. Khalid ibn al-Walid used his military tactics to outmaneuver the Roman army and take control of the battlefield. The battle lasted for six days, with both sides suffering heavy losses. However, th
