Al-Maris (Arabic: المريس‎‎) was a Medieval Arabic name for Lower Nubia, the region of the Nile around the first and second cataracts, including Aswan. Because most of the sources for Nubian history during the period are in Arabic, it is sometimes used interchangeably with the Nubian region of Nobadia. The northern section of al-Maris was part of Fatimid Upper Egypt and was semi-independent under the Kanz ad-Dawla between 1046 and 1077 AD. The Kanz ad-Dawla Nasir invaded Nubia in 1066 but was repulsed and his territory raided.
