I want to know the answer to the following question:
What is the result of the incorporation of independent kingdoms and sultanates?
All the background I'm provided with is that "The creation of modern-day Eritrea is a result of the incorporation of independent, distinct kingdoms and sultanates (for example, Medri Bahri and the Sultanate of Aussa) eventually resulting in the formation of Italian Eritrea.". Is that enough to answer the question?
Answer: yes
