The name Saigon was used officially in 1698, when Lord Nguyen Phuc Chu sent Mr. Nguyen Huu Canh to this region to create various districts and to form a government for this southern outpost. Because of its strategic location for trade and commerce as well as military importance, Saigon continued to grow and became a bonafide city. By 1772, Mr. Nguyen Cuu Dam began to fill many of the canals to form streets.
