Kerma, Nepata and Meroe were Nubia's largest population centres. The rich agricultural lands of Nubia supported these cities. Ancient Egyptian rulers sought control of Nubia's wealth, including gold, and the important trade routes within its territories. Nubia's trade links with Egypt led to Egypt's domination over Nubia during the New Kingdom period. The emergence of the Kingdom of Meroe in the 8th century BC led to Egypt being under the control of Nubian rulers for a century, although they preserved many Egyptian cultural traditions. Nubian kings were considered pious scholars and patrons of the arts, copying ancient Egyptian texts and even restoring some Egyptian cultural practices. After this, Egypt's influence declined greatly. Meroe became the centre of power for Nubia and cultural links with sub-Saharan Africa gained greater influence.
