1. Ibn Battuta (1304-1369)
In 1325, at the age of only 21, Ibn Battuta set out on the hajj, a pilgrimage made by Muslims, from his homeland of Morocco to Mecca. Thus began a 75,000-mile journey that would take him across the Islamic world and beyond, over a span of two decades. Battuta travelled through Syria, onward to Turkey, down the eastern coast of Africa to India, and eventually reached Indonesia and China.
