During the seventh century BCE, the power of the Egyptian empire had waned substantially. The territory had been ruled by foreign invaders (from Libya and Nubia) for several generations and the state was greatly weakened by internal conflict and decentralization of power. The rising Assyrian Empire, which emerged in the Middle East, took advantage of this situation and conquered most of Egypt in the seventh century.

The Sack of Jerusalem took place during the tenth century BCE. It is generally believed that the Egyptian forces were led by one of the Libyan rulers of Egypt, most likely Shoshenq I. Although, there is a considerate amount of disagreement among historians and Egyptologists owing to the paucity of reliable historical evidence from this time period. 

We know the most about the Sea Peoples from Egyptian accounts such as the Great Karnak Inscription of Merneptah, although similar phenomena are described in Levantine, Anatolian and Mesopotamian sources, suggesting a massive marine migration of loosely affiliated peoples who disrupted the stability of the entire region. These migrations and invasions were an essential, although not the only, element in what is described as the Bronze Age Collapse. Rather than the powerful empires consolidating their strength and spheres of influences, instead this resulted in the destruction of long-standing states (the Hittite Empire and Mycenaean Greece), as well as the immense weakening of Egypt during its transition from the New Kingdom to the Third Intermediate Period. Egypt eventually weakened to the point that it became susceptible to conquest by the Assyrians, and then in turn the Babylonians, Persians, Greeks and Romans. While the Sea Peoples are sometimes blamed from the collapse of Mycenaean civilization, an alternative postulation is that the Sea Peoples themselves consisted of native Greeks displaced by political and environmental factors, forcing them to travel by sea to populate and invade Egypt and the Levant. This is supported by linguistic and archaeological evidence of the Philistines, who appear to have spoken an Indo-European language related to Greek, and whose art and pottery strongly resembles earlier Greek forms. 

King Kashta of Kush invaded Egypt during the 8th Century BCE, conquering the country. The emperors of Kush then ruled as pharaohs of Egypt for the 25th dynasty, until they were removed by the Assyrians. 

The Battle of Megiddo was fought in 609 BCE. It was part of a larger conflict between the declining Assyrian Empire and the ascending Neo-Babylonian Empire. The Egyptians were led by Necho II, an Assyrian puppet ruler. The Battle of Megiddo was fought between Egypt and the Kingdom of Judah (a would-be ally of the Neo-Babylonians). It ended in victory for the forces of Egypt and Necho II, which captured Judah and joined up with the Assyrian army at Carchemish. It proved to be a pyrrhic victory, however, as the combined Egyptian and Assyrian army was promptly destroyed by the forces of Nebuchadnezzar II and the Neo-Babylonian Empire.

The Battle of Carchemish was fought in 605 BCE. It was contended by an alliance of Assyria and Egypt and an alliance of Babylon and Persia. It ended in the complete destruction of the Egyptian army, the downfall of the Assyrian Empire, and the ascendancy of the Neo-Babylonian Empire.

The Elephantine papyri are a collection of brief papyri written in Aramaic by the Jewish community of Elephantine, on the Nile in Upper Egypt. They were written over a long period, but especially during the 5th century BCE, and it is likely that the Jewish community of Elephantine originated as an Israelite garrison which was sent centuries earlier by the King of Judah in order to assist its weak Egyptian ally against incursions from the Nubians. The papyri show that the Elephantine Jews worshiped the Israelite god Yahweh but within a polytheistic Egyptian setting and constructed their own temple to Yahweh at Elephantine, while still keeping in close contact with the Jews of the Land of Israel and sending contributions to the Jerusalem Temple. The other answers roughly correspond  to the Great Hymn to the Aten (commissioned by Pharaoh Akhenaten), the Book of the Dead (the funerary texts), the Amarna letters (the diplomatic correspondence) and the Great Karnak Inscription (Merneptah's narration of his battles against the Sea Peoples).

The Battle of Megiddo was fought in the seventh century BCE, between the forces of Egypt (led by Necho II) and the Kingdom of Judah. It was part of a larger war between Assyria and the Neo-Babylonian Empire. The Battle of Megiddo ended in victory for the Egyptians and allowed Necho II to claim the Kingdom of Judah as a vassal state.

The Brooklyn Papyrus is an ancient medical text dating from around 450 BCE. It is significant as one of the oldest existing medical documents, and it systematically described different types of snakes, then provided possible remedies for the bite of each. It also has remedies for spider and scorpion bites. The means of curing the snakebites included practical remedies as well as spells to be performed by a healing priest. 

The Earl of Carnarvon funded an archaeological expedition in Egypt in the early twentieth century. It was on this expedition that the legendary tomb of Tutankhamun was found and opened. The Earl died shortly after, which encouraged the spread of the “curse of the mummy” in popular culture. The “curse of the mummy” suggests that anyone who opens a dead Pharaoh’s tomb risks incurring the wrath of the deceased and will certainly die shortly thereafter.
