Amarna Period

The Amarna period was a time during the 18th Dynasty, from 934 to 897 B.C., during which the capital of Egypt was transferred from Thebes to Amarna. This began under the reign of Akhenaten, and lasted through to the time of Horemheb. A lot is known about this period, more so in the traditional history.

This began in 934 B.C., during the reigns of Amenhotep III and Akhenaten. Akhenaten changed the religion of Egypt to a monotheism, and moved the capital of Egypt to Akhetaten (Amarna) in this year. Four years later, Solomon of Israel died, and the kingdom was split into Judah (ruled by Rehoboam) and Israel (ruled by Labaya/Jeroboam). As Labaya was the brother-in-law of Akhenaten, this renewed interest in the Levant for Egypt.

In 925 B.C., Akhenaten invaded Judah and captured Jerusalem, putting an Egyptian official (Abdi-Hiba) there to watch over Rehoboam. A civil war between Labaya and Rehoboam caused the Egyptians in the Levant to call on Akhenaten, and later Ay, to help. This led to a large-scale correspondence now known as the Amarna letters.

This period of monotheism continued into the reign of Tutankhamen, who reverted Egypt back to the old religion. He died, and an interregnum followed from 904 to 897 B.C. in which Horemheb ruled as commander of the Egyptian army. Following this, Horemheb declared himself pharaoh, and moved the capital back to Thebes.
