Polylobed Arch
A multifoil arch (or polyfoil arch), also known as a cusped arch, polylobed arch, or scalloped arch, is an arch characterized by multiple circular arcs or leaf shapes (called foils, lobes, or cusps) that are cut into its interior profile or intrados. The term ''foil'' comes from the old French word for "leaf." A specific number of foils is indicated by a prefix: trefoil (three), quatrefoil (four), cinquefoil (five), sexfoil (six), octofoil (eight). The term multifoil or scalloped is specifically used for arches with more than five foils. The multifoil arch is characteristic of Islamic art and architecture; particularly in the Moorish architecture of al-Andalus (Iberian Peninsula) and North Africa and in Mughal architecture of the Indian subcontinent. Variants of the multifoil arch, such as the trefoil arch, are also common in other architectural traditions such as Gothic architecture.  Origins The first multifoil arches were developed by the Umayyads and can be found in a sm ...

Middle East
The Middle East (term originally coined in English language) is a geopolitical region encompassing the Arabian Peninsula, the Levant, Turkey, Egypt, Iran, and Iraq. The term came into widespread usage by the United Kingdom and western European nations in the early 20th century as a replacement of the term Near East (both were in contrast to the Far East). The term "Middle East" has led to some confusion over its changing definitions. Since the late 20th century, it has been criticized as being too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of West Asia, but without the South Caucasus. It also includes all of Egypt (not just the Sinai Peninsula, Sinai) and all of Turkey (including East Thrace). Most Middle Eastern countries (13 out of 18) are part of the Arab world. The list of Middle Eastern countries by population, most populous countries in the region are Egypt, Turkey, and Iran, whil ...

Abbasid Caliphate
The Abbasid Caliphate or Abbasid Empire (; ) was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib (566–653 CE), from whom the dynasty takes its name. After overthrowing the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132  AH), they ruled as caliphs based in modern-day Iraq, with Baghdad being their capital for most of their history. The Abbasid Revolution had its origins and first successes in the easterly region of Khurasan, far from the Levantine center of Umayyad influence. The Abbasid Caliphate first centered its government in Kufa, modern-day Iraq, but in 762 the caliph al-Mansur founded the city of Baghdad as the new capital. Baghdad became the center of science, culture, arts, and invention in what became known as the Golden Age of Islam. By housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi- ...
