Umayyad architectureUmayyad architecture developed in the Umayyad Caliphate between 661 and 750, primarily in its heartlands of Syria and Palestine. It drew extensively on the architecture of older Middle Eastern and Mediterranean civilizations including the Sassanian Empire and Byzantine Empire, but introduced innovations in decoration and form. Under Umayyad patronage, Islamic architecture began to mature and acquire traditions of its own, such as the introduction of mihrabs to mosques, a trend towards aniconism in decoration, and a greater sense of scale and monumentality compared to previous Islamic buildings.
SahnA sahn (صَحْن, ), is a courtyard in Islamic architecture, especially the formal courtyard of a mosque. Most traditional mosques have a large central sahn, which is surrounded by a riwaq or arcade on all sides. In traditional Islamic design, residences and neighborhoods can have private sahn courtyards. The sahn is a common element in religious buildings and residences throughout the Muslim world, used in urban and rural settings. The cloister is its equivalent in European medieval architecture and its religious buildings.
Abbasid architectureAbbasid architecture developed in the Abbasid Caliphate between 750 and 1227, primarily in its heartland of Mesopotamia (modern Iraq). The great changes of the Abbasid era can be characterized as at the same time political, geo-political and cultural. The Abbasid period starts with the destruction of the Umayyad ruling family and its replacement by the Abbasids, and the position of power is shifted to the Mesopotamian area.
Abbasid dynastyThe Abbasid dynasty or Abbasids (Banu al-ʿAbbās) were an Arab dynasty that ruled the Abbasid Caliphate between 750 and 1258. They were from the Qurayshi Hashimid clan of Banu Abbas, descended from Abbas ibn Abd al-Muttalib. The Abbasid Caliphate is divided into three main periods: Early Abbasid era (750–861), Middle Abbasid era (861–936) and Later Abbasid era (936–1258). A cadet branch of the dynasty also ruled as ceremonial rulers for the Mamluk Sultanate as Caliph (1261–1517), until their conquest by the Ottoman Empire.
Riwaq (arcade)A riwaq (or rivaq, رواق or ) is an arcade or portico (if in front of entrances) open on at least one side. It is an architectural design element in Islamic architecture and Islamic garden design. A riwaq often serves as the transition space between interior and outdoor spaces. As portico or arcade structure, it provides shade and adjustment to sunlight in hot climates, and cover from rain in any locale. As an arcade element the structure is often found surrounding and defining the courtyards (sahn) of mosques and madrasas, and used for covered circulation, meeting and rest, and ritual circumambulation.
Bayt al-malBayt al-mal (بيت المال) is an Arabic term that is translated as "House of money" or "House of wealth." Historically, it was a financial institution responsible for the administration of taxes in Islamic states, particularly in the early Islamic Caliphate. It served as a royal treasury for the caliphs and sultans, managing personal finances and government expenditures. Further, it administered distributions of zakat revenues for public works. Modern Islamic economists deem the institutional framework appropriate for contemporary Islamic societies.
Cairo CitadelThe 'Citadel of Cairo or Citadel of Saladin' (Qalaʿat Salāḥ ad-Dīn) is a medieval Islamic-era fortification in Cairo, Egypt, built by Salah ad-Din (Saladin) and further developed by subsequent Egyptian rulers. It was the seat of government in Egypt and the residence of its rulers for nearly 700 years from the 13th to the 19th centuries. Its location on a promontory of the Mokattam hills near the center of Cairo commands a strategic position overlooking the city and dominating its skyline.
