King Mansa Musa, the owner and Lord of the Mines governed his people with strict law yet making sure no one lack food and cloths. And when he determined to travel to Mecca, he unknowingly and single handedly caused the worlds well know Gold crush where all who saw and welcomed him; even the Sorcerer of Luxor went home with not less than five kilograms of pure yellow metal we all know today as gold.
The Lord of Wangara in a company of his Ghanata Sahara elite soldiers and score of servants distributed and dashed enough gold on his way to Mecca that; port Alexandria in Egypt had enough gold to buy a moderate European Kingdom.
