Islamic architecture developed from the 7th century onward in countries where Islam became dominant. Key features of Islamic architecture include mosques, tombs, and palaces. The earliest mosques were simple square enclosures surrounded by reeds. Over time, mosques developed architectural elements like minarets, mihrabs, iwans, courtyards, and domes. Islamic architecture spread across regions through trade routes and military conquests, adapting to local materials and climates. Mosques became focal points for communities and incorporated elements symbolizing religious beliefs and social functions.
