Answer: Old Kingdom
Step-by-step explanation:
During the Old Kingdom period in ancient Egypt, pyramids were the most common royal tombs. The Old Kingdom period lasted from around 2686 BCE to 2181 BCE. Pharaohs, who were the rulers of ancient Egypt, commissioned the construction of these monumental structures to serve as their final resting places.
Pyramids were built to honor and protect the pharaoh's body after death and ensure their successful journey into the afterlife.
