Muhammad al-Idrisi in the context of "Geography and cartography in medieval Islam"

Geography (from Ancient Greek γεωγραφία geōgraphía; combining gê 'Earth' and gráphō 'write', literally 'Earth writing') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines."

The history of geography as a discipline spans cultures and millennia, being independently developed by multiple groups, and cross-pollinated by trade between these groups. Geography as a discipline dates back to the earliest attempts to understand the world spatially, with the earliest example of an attempted world map dating to the 9th century BCE in ancient Babylon. Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (c. 276 BC – c. 195/194 BC). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). During the Middle Ages, geography was influenced by Islamic scholars, like Muhammad al-Idrisi, producing detailed maps of the world. The Age of Discovery was influential in the development of geography, as European explorers mapped the New World. Modern developments include the development of geomatics and geographic information science.

Medieval Islamic geography and cartography were the study of geography and cartography in the Muslim world during the Islamic Golden Age (variously dated between the 8th century and 16th century). Muslim scholars made advances to the map-making traditions of earlier cultures, explorers and merchants learned in their travels across the Old World (Afro-Eurasia). Islamic geography had three major fields: exploration and navigation, physical geography, and cartography and mathematical geography. Islamic geography reached its apex with Muhammad al-Idrisi in the 12th century.

The history of Sicily has been influenced by numerous ethnic groups. It has seen Sicily controlled by powers, including Carthaginian, Greek, Roman, Vandal and Ostrogoth, Byzantine, Arab, Norman, Aragonese, Spanish, Austrians, but also experiencing important periods of independence, as under the indigenous Sicanians, Elymians, Sicels, the Greek-Siceliotes (in particular Syracuse with its sovereigns), and later as County of Sicily, and Kingdom of Sicily. The Kingdom was founded in 1130 by Roger II, belonging to the Siculo-Norman family of Hauteville. During this period, Sicily was prosperous and politically powerful, becoming one of the wealthiest states in all of Europe. As a result of the dynastic succession, the Kingdom passed into the hands of the Hohenstaufen. At the end of the 13th century, with the War of the Sicilian Vespers between the crowns of Anjou and Aragon, the island passed to the latter. In the following centuries the Kingdom entered into the personal union with the Spaniard and Bourbon crowns, while preserving effective independence until 1816. Sicily was merged with the Kingdom of Italy in 1861.Although today an Autonomous Region, with special statute, of the Republic of Italy, it has its own distinct culture.

Sicily is both the largest region of the modern state of Italy and the largest island in the Mediterranean Sea. Its central location and natural resources ensured that it has been considered a crucial strategic location due in large part to its importance for Mediterranean trade routes. Cicero and al-Idrisi described respectively Syracuse and Palermo as the greatest and most beautiful cities of the Hellenic World and of the Middle Ages.

Mombasa (/mɒmˈbæsə/ mom-BASS-ə; also US: /-ˈbɑːsə/ -⁠BAH-sə) is a coastal city in southeastern Kenya along the Indian Ocean. It was the first capital of British East Africa, before Nairobi was elevated to capital status in 1907. It now serves as the capital of Mombasa County. Buildings in the CBD are blue and white, representing the Indian Ocean. It is the country's oldest (c. 900 A.D.) and second-largest city after Nairobi, with a population of about 1,208,333 people according to the 2019 census.

Mombasa's location on the Indian Ocean made it a historical trading centre, and it has been controlled by many countries because of its strategic location. Kenyan school history books place the founding of Mombasa as 900 AD. It must have been already a prosperous trading town in the 12th century, as the Arab geographer al-Idrisi mentions it in 1151. It was a part of the Kilwa Sultanate from approximately the early 14th century until the dissolution of the sultanate in 1513. The oldest stone mosque in Mombasa, Mnara, was built c. 1300. The Mandhry Mosque, built in 1570, has a minaret that contains a regionally specific ogee arch. The city later came under the occupation and control of the Omani Empire in the late 17th century.

Arabia Deserta (Latin for lit. 'Deserted Arabia'), also known as Arabia Magna (lit. 'Great Arabia'), signified the desert interior of the Arabian Peninsula, delineated to the northeast by the Euphrates. In ancient times, this land was populated by nomadic Bedouin tribes.

Arabia Deserta was one of three regions into which the Romans divided the Arabian peninsula: Arabia Deserta (or Arabia Magna), Arabia Felix, and Arabia Petraea. As a name for the region, it remained popular into the 19th and 20th centuries, and was used in Charles M. Doughty's Travels in Arabia Deserta (1888).
