Geography 🗾

Invention/Contribution:

• Muslim scholars became world leaders in geography between the 9th–14th centuries.

• Al-Idrisi (1100–1165) created the Tabula Rogeriana, one of the most accurate world maps of its time, for King Roger II of Sicily.

• Al-Biruni (973–1048) measured Earth’s circumference with near-modern accuracy and described continents and seas.

• Ibn Battuta (1304–1369) traveled over 75,000 miles, recording cultures, cities, and landscapes in his famous travelogue.

• Muslim geographers mapped trade routes, rivers, mountains, and climates, linking science with exploration.

Why it matters:

• Corrected and expanded Greek, Indian, and Persian knowledge of the world.

• Guided travelers, merchants, and pilgrims across continents.

• Laid foundations for European exploration and cartography.

“He who knows geography knows himself.”

Al-Idrisi, Nuzhat al-Mushtaq (12th century)

From desert caravans to ocean voyages, Muslims charted the world with science and curiosity. Al-Idrisi drew a world map that guided travelers for centuries, while Al-Biruni calculated Earth’s size with precision. The legendary traveler Ibn Battuta journeyed across Africa, Asia, and Europe, recording the diversity of God’s creation. For Muslims, geography was more than maps — it was knowledge that connected people, cultures, and faith across the globe.
