The Hyksos brought several technical innovations to Egypt, as well as cultural imports such as new musical instruments and foreign loanwords. The changes introduced include new techniques of bronze-working and pottery, new breeds of animals, and new crops. In warfare, they introduced the horse and chariot, the composite bow, improved battle axes, and advanced fortification techniques. These cultural advances received from the Hyksos became a decisive factor in Egypt’s later success in building an empire in the Middle East during the New Kingdom.
