Early conquests
It seems man began making maps around 6th century BC. The ancient Romans made maps as they expanded their empire. The ancient Chinese were also making maps by at least the 5th century. The first emperor of China, Qin Shihuang (259 BC - 210 BC), needed maps when he unified the country. Some Chinese maps that are around 2,500 years old still exist.
The oldest map of the world was made by a Greek called Ptolemy. He made it around 150 AD. In those days, there were many places in the world people didn't know about. The map included Europe, China and India.
Getting around
At some time in our life - probably many times - we all have to use a map.
A map is a drawing of an area - or even the whole world - on a flat surface. The formal word for this is cartography. Someone who makes maps is called a cartographer.
