A ribāṭ is an Arabic term, initially designating a small fortification built along a frontier during the first years of the Muslim conquest of the Maghreb to house military volunteers, called murabitun, and shortly after they also appeared along the Byzantine frontier, where they attracted converts from Greater Khorasan, an area that would become known as al-ʻAwāṣim in the ninth century CE.

A caravanserai was a roadside inn where travelers (caravaners) could rest and recover from the day's journey. Caravanserais supported the flow of commerce, information and people across the network of trade routes covering Asia, North Africa and Southeast Europe, most notably the Silk Road. Often located along rural roads in the countryside, urban versions of caravanserais were also historically common in cities throughout the Islamic world, and were often called other names such as khan, wikala, or funduq.
