Meta- (from Greek: μετά = "after", "beyond", "adjacent", "self"), is a prefix used in English (and other Greek-owing languages) to indicate a concept which is an abstraction from another concept, used to complete or add to the latter.

In epistemology, the prefix meta- is used to mean about (its own category). For example, metadata are data about data (who has produced them, when, what format the data are in and so on). Also, metamemory in psychology means an individual's knowledge about whether or not they would remember something if they concentrated on recalling it. Furthermore, metaemotion in psychology means an individual's emotion about his/her own basic emotion, or somebody else's basic emotion.

Another, slightly different interpretation of this term is "about" but not "on" (exactly its own category). For example, in linguistics a grammar is considered as being expressed in a metalanguage, or a sort of language for describing another language (and not itself).

Any subject can be said to have a meta-theory which is the theoretical consideration of its meta-properties, such as its foundations, methods, form and utility.

An ethnic group is a group of people who share a common ethnicity. That is, its members identify with each other through a common heritage, consisting of a common culture, including a shared language or dialect. The group's ethos or ideology may also stress common ancestry, religion, or race.

The process that results in the emergence of an ethnicity is called ethnogenesis.

The terms ethnicity and ethnic group are derived from the Greek word ἔθνος ethnos, normally translated as "nation". The terms refer currently to people thought to have common ancestry who share a distinctive culture.

Herodotus is the first who stated the main characteristics of ethnicity in the 5th century BC, with his famous account of what defines Greek identity, where he lists kinship (Greek: ὅμαιμον - homaimon, "of the same blood"), language (Greek: ὁμόγλωσσον - homoglōsson, "speaking the same language"), cults and customs (Greek: ὁμότροπον - homotropon, "of the same habits or life").

The term "ethnic" and related forms from the 14th through the middle of the 19th century were used in English in the meaning of "pagan, heathen", as ethnikos (Greek: ἐθνικός, literally "national") was used as the LXX translation of Hebrew goyim "the nations, non-Hebrews, non-Jews".

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.
