The greatest of the court artists enriched the Ottoman Empire with many pluralistic artistic influences: such as mixing traditional Byzantine art with elements of Chinese art.
Document 6: Somalis: The peaceful introduction of Islam in the early medieval era of Somalia's history brought Islamic architectural influences from Arabia and Persia. This had the effect of stimulating a shift in construction from drystone and other related materials to coral stone, sundried bricks, and the widespread use of limestone in Somali architecture.

The name refers to unusual minaret with three balconies (Turkish: üç şerefeli).The architect of the mosque is not known. It is built of Burgaz limestone with a main dome that is 24 m in diameter. When first built the dome was the largest in any Ottoman building. The mosque was severely damaged by fire in 1732 and by an earthquake in 1748 but was repaired on the order of Mahmut I.The two blue and turquoise underglaze-painted tile panels in the tympana of the windows were probably produced by the same group of tilemakers who had decorated the Yeşil Mosque (1419–21) in Bursa where the tiles are signed as "the work of the masters of Tabriz" (ʿamal-i ustadan-i Tabriz). The running pattern of the Chinese influenced floral border tiles is similar to those in the small Muradiye Mosque in Edirne.In the Şakaiki Numaniye Taş Köprü Zade  relates how 'Certain accursed ones of no significance' were burnt to death by Mahmut Paşa who accidentally set fire to his beard in the process.
Document 11: Somalis: The birth of Islam on the opposite side of Somalia's Red Sea coast meant that Somali merchants, sailors and expatriates living in the Arabian Peninsula gradually came under the influence of the new religion through their converted Arab Muslim trading partners. With the migration of fleeing Muslim families from the Islamic world to Somalia in the early centuries of Islam and the peaceful conversion of the Somali population by Somali Muslim scholars in the following centuries, the ancient city-states eventually transformed into Islamic Mogadishu, Berbera, Zeila, Barawa and Merca, which were part of the Berberi civilization.

With the beginning of the Indus civilization around the middle of the 3rd millennium BCE, an advanced urban culture developed for the first time in the region, with large buildings, some of which survive to this day. Mohenjo Daro, Harappa, and Kot Diji are among the pre-Islamic settlements that are now tourist attractions. The rise of Buddhism and the influence of Greek civilisation led to the development of a Greco-Buddhist style, starting from the 1st century CE. The high point of this era was the Gandhara style. An example of Buddhist architecture is the ruins of the Buddhist monastery Takht-i-Bahi in Khyber-Pakhtunkhwa.

The role of domes in Islamic architecture has been considerable. Its usage spans centuries, first appearing in 691 with the construction of the Dome of the Rock mosque, and recurring even up until the 17th century with the Taj Mahal.
