Final answer:
The early theocracies changed to dynasties due to changes in royal authority and the rise of the nobility, among other factors.
Step-by-step explanation:
The early theocracies gradually changed to dynasties due to various factors. In ancient Egypt, for example, dynastic divisions were created by an Egyptian priest named Manetho in the 3rd century BCE. These dynasties were formed based on kinship or the location of the rulers' seat of power. As time went on, changes in royal authority and the rise of the nobility led to the transition from theocracies to dynasties.
During the Intermediate Period in Egypt, royal authority weakened and the nobility grew in power. This shift in power dynamics played a role in the shift from theocratic rule to dynastic rule. Additionally, the collapse of centralized power in North Africa and changing military realities contributed to the rise of dynasties in the Muslim-held portions of the Mediterranean.
In summary, the early theocracies gradually changed to dynasties due to factors such as changes in royal authority, the rise of the nobility, and changing military and political landscapes.
