What Dynasties built the Great wall?

During the Zhou Dynasty there were a lot of feudal states which each built part of the wall to defend against the invaders from the north of China. The wall was joined together in the Qin Dynasty and they added on to it so it was really built by the Qin Dynasty. Several other dynasties later also repaired and added on to the wall, such as Han, Sui, an Jin. The last to do so was the Ming Dynasty.
