Lake Nasser (Arabic: بحيرة ناصر‎ Boħēret Nāṣer, Egyptian Arabic: [boˈħeːɾet ˈnɑːsˤeɾ]) is a vast reservoir in southern Egypt, and northern Sudan, and is one of the largest man-made lakes in the world. Strictly, "Lake Nasser" refers only to the much larger portion of the lake that is in Egyptian territory (83% of the total), with the Sudanese preferring to call their smaller body of water Lake Nubia (Egyptian Arabic: بحيرة نوبية Boħēret Nubeyya, [boˈħeːɾet nʊˈbejjæ]). The area of Sudan-administered Wadi Halfa Salient was largely flooded by Lake Nasser/Lake Nubia.

The lake is some 550 km long and 35 km across at its widest point, which is near the Tropic of Cancer. It covers a total surface area of 5,250 km² and has a storage capacity of some 157 km³ of water.

The lake was created as a result of the construction of the Aswan High Dam across the waters of the Nile between 1958 and 1971. The lake is named after Gamal Abdel Nasser, one of the leaders of the Egyptian Revolution of 1952, and the second President of Egypt, who initiated the High Dam project.

Nubia is a region along the Nile river, which is located in northern Sudan and southern Egypt.

There were a number of small Nubian kingdoms throughout the Middle Ages, the last of which collapsed in 1504, when Nubia became divided between Egypt and the Sennar sultanate resulting in the Arabization of much of the Nubian population. Nubia was again united within Ottoman Egypt in the 19th century, and within Anglo-Egyptian Sudan from 1899 to 1956.

The name Nubia is derived from that of the Noba people, nomads who settled the area in the 4th century, with the collapse of the kingdom of Meroë. The Noba spoke a Nilo-Saharan language, ancestral to Old Nubian. Old Nubian was used in mostly religious texts dating from the 8th and 15th centuries AD. Before the 4th century, and throughout classical antiquity, Nubia was known as Kush, or, in Classical Greek usage, included under the name Ethiopia (Aithiopia).

Historically, the people of Nubia spoke at least two varieties of the Nubian language group, a subfamily which includes Nobiin (the descendant of Old Nubian), Kenuzi-Dongola, Midob and several related varieties in the northern part of the Nuba Mountains in South Kordofan. A variety (Birgid) was spoken (at least until 1970) north of Nyala in Darfur but is now extinct.

Ramesses II (c. 1303 BC – July or August 1213 BC; Egyptian: *Riʻmīsisu, alternatively transcribed as Rameses  /ˈræməsiːz/ and Ramses /ˈræmsiːz/ or /ˈræmziːz/), referred to as Ramesses the Great, was the third Egyptian pharaoh (reigned 1279 BC – 1213 BC) of the Nineteenth dynasty. He is often regarded as the greatest, most celebrated, and most powerful pharaoh of the Egyptian Empire. His successors and later Egyptians called him the "Great Ancestor." Ramesses II led several military expeditions into the Levant, re-asserting Egyptian control over Canaan. He also led expeditions to the south, into Nubia, commemorated in inscriptions at Beit el-Wali and Gerf Hussein.

At age fourteen, Ramesses was appointed Prince Regent by his father Seti I. He is believed to have taken the throne in his late teens and is known to have ruled Egypt from 1279 BC to 1213 BC for 66 years and 2 months, according to both Manetho and Egypt's contemporary historical records. He was once said to have lived to be 99 years old, but it is more likely that he died in his 90th or 91st year. If he became Pharaoh in 1279 BC as most Egyptologists today believe, he would have assumed the throne on May 31, 1279 BC, based on his known accession date of III Shemu day 27. Ramesses II celebrated an unprecedented 14 sed festivals (the first held after thirty years of a pharaoh's reign, and then every three years) during his reign—more than any other pharaoh. On his death, he was buried in a tomb in the Valley of the Kings; his body was later moved to a royal cache where it was discovered in 1881, and is now on display in the Cairo Museum.
