Thurayya Palace
The Thurayya Palace ( ar, قصر الثريا, Qaṣr al-Thurayyā, Palace of the Pleiades) was a caliphal palace built in East Baghdad by the Abbasid caliph al-Mu'tadid (). It lay at the Musa Canal, adjacent to the Great Divide, where the canal split in three, some two miles east from the older Hasani Palace, and most likely outside the city wall built around East Baghdad in the 11th century. The Thurayya, Hasani, Firdus Palace, Firdus, and Taj Palace, Taj palaces combined into a sprawling palace complex, the "Abode of the Caliphate" (), comprising several major and minor residences and gardens. This remained the main caliphal residence for the remainder of the Abbasid Caliphate. The Thurayya was connected with the Hasani by an underground passage, which allowed the caliph, his harem, and his servants to move between the palaces unseen. This passage continued to be used until the great floods of 1074 flooded the entirety of East Baghdad. The historian Mas'udi reports that the pa ...

Baghdad 150 To 300 AH
Baghdad (; ar, بَغْدَاد , ) is the capital of Iraq and the list of largest cities in the Arab world, second-largest city in the Arab world after Cairo. It is located on the Tigris near the ruins of the ancient city of Babylon and the Sassanid Empire, Sassanid Persian capital of Ctesiphon. In 762 CE, Baghdad was chosen as the capital of the Abbasid Caliphate, and became its most notable major development project. Within a short time, the city evolved into a significant cultural, commercial, and intellectual center of the Muslim world. This, in addition to housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi-religious environment, garnered it a worldwide reputation as the "Center of Learning". Baghdad was the largest city in the world for much of the Abbasid era during the Islamic Golden Age, peaking at a population of more than a million. The city was largely Siege of Baghdad (1258), destroyed at the hands of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleiades
The Pleiades (), also known as The Seven Sisters, Messier 45 and other names by different cultures, is an asterism and an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. At a distance of about 444 light years, it is among the nearest star clusters to Earth. It is the nearest Messier object to Earth, and is the most obvious cluster to the naked eye in the night sky. It is also observed to house the reflection nebula NGC 1432, an HII Ionized region. The cluster is dominated by hot blue luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be left over material from their formation, but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing. This dust cloud is estimated to be moving at a speed of approximately 18 km/s relative to the stars in the cluster. Computer sim ...

Caliph
A caliphate or khilāfah ( ar, خِلَافَة, ) is an institution or public office under the leadership of an Islamic steward with the title of caliph (; ar, خَلِيفَة , ), a person considered a political-religious successor to the Islamic prophet Muhammad and a leader of the entire Muslim world (ummah). Historically, the caliphates were polities based on Islam which developed into multi-ethnic trans-national empires. During the medieval period, three major caliphates succeeded each other: the Rashidun Caliphate (632–661), the Umayyad Caliphate (661–750), and the Abbasid Caliphate (750–1258). In the fourth major caliphate, the Ottoman Caliphate, the rulers of the Ottoman Empire claimed caliphal authority from 1517. Throughout the history of Islam, a few other Muslim states, almost all hereditary monarchies such as the Mamluk Sultanate (Cairo) and Ayyubid Caliphate, have claimed to be caliphates. The first caliphate, the Rashidun Caliphate, was established in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
