Ur-Nammu (or Ur-Namma, Ur-Engur, Ur-Gur, ca. 2047-2030 BC short chronology) founded the Sumerian 3rd dynasty of Ur, in southern Mesopotamia, following several centuries of Akkadian and Gutian rule. His main achievement was state-building, and Ur-Nammu is chiefly remembered today for his legal code, the Code of Ur-Nammu, the oldest known surviving example in the world.

Year-names are known for 17 of Ur-Nammu's 18 years, but their order is uncertain. One year-name of his reign records the devastation of Gutium, while two years seem to commemorate his legal reforms: "Year in which Ur-Nammu the king put in order the ways (of the people in the country) from below to above", and "Year Ur-Nammu made justice in the land".

Among his military exploits were the conquest of Lagash and the defeat of his former masters at Uruk. He was eventually recognized as a significant regional ruler (of Ur, Eridu, and Uruk) at a coronation in Nippur, and is believed to have constructed buildings at Nippur, Larsa, Kish, Adab, and Umma. He was known for restoring the roads and general order after the Gutian period.

Zecharia Sitchin (July 11, 1920 – October 9, 2010) was an Azerbaijani-born American author of books proposing an explanation for human origins involving ancient astronauts. Sitchin attributes the creation of the ancient Sumerian culture to the Anunnaki, which he states was a race of extra-terrestrials from a planet beyond Neptune called Nibiru. He believed this hypothetical planet of Nibiru to be in an elongated, elliptical orbit in the Earth's own Solar System, asserting that Sumerian mythology reflects this view. Sitchin's books have sold millions of copies worldwide and have been translated into more than 25 languages.

Sitchin's ideas were rejected by scientists and academics, who dismiss his work as pseudoscience and pseudohistory. Sitchin's work has been criticized for flawed methodology and mistranslations of ancient texts as well as for incorrect astronomical and scientific claims.

Sitchin was born in the then Azerbaijan SSR of the Soviet Union, but was raised in Palestine. He received a degree in economics from the University of London, and was an editor and journalist in Israel, before moving to New York in 1952. While working as an executive for a shipping company, he taught himself Sumerian cuneiform and visited several archaeological sites.

Saddam Hussein Abd al-Majid al-Tikriti (Arabic: صدام حسين عبد المجيد التكريتي Ṣaddām Ḥusayn ʿAbd al-Maǧīd al-Tikrītī; 28 April 1937 – 30 December 2006) was the fifth President of Iraq, serving in this capacity from 16 July 1979 until 9 April 2003. A leading member of the revolutionary Arab Socialist Ba'ath Party, and later, the Baghdad-based Ba'ath Party and its regional organisation Ba'ath Party – Iraq Region, which espoused ba'athism, a mix of Arab nationalism and Arab socialism, Saddam played a key role in the 1968 coup, later referred to as the 17 July Revolution, that brought the party to long-term power of Iraq.

As vice president under the ailing General Ahmed Hassan al-Bakr, and at a time when many groups were considered capable of overthrowing the government, Saddam created security forces through which he tightly controlled conflict between the government and the armed forces. In the early 1970s, Saddam nationalized oil and other industries. The state-owned banks were put under his control, leaving the system eventually insolvent mostly due to the Iran–Iraq War, the Gulf War, and UN sanctions. Through the 1970s, Saddam cemented his authority over the apparatuses of government as oil money helped Iraq's economy to grow at a rapid pace. Positions of power in the country were filled with Sunnis, a minority that made up only a fifth of the population.
