In 1325, when Ibn Battuta was 20 years old, he started travelling, as he wanted to go on a Pilgrimage to Mecca, which is called as Hajj as all Muslims wanted to go there so he was also interested to go there. But, in actual his travelling time went to about 29 years and during which he almost covered 75,000 miles distance, and this was actually equivalent to that of 44 modern countries. During his travelling, he had much adventurous life, and also he met with many dangers on his way, like once he was attacked by bandits, and once he was almost drowned in a sinking ship. He had a few marriages, lovers during his travelling and he also became the father of several children, all this happened during his travelling.
