The 1969 Sudanese coup d'état was a successful coup, led by Colonel Gaafar Nimeiry, against the government of President Ismail al-Azhari. The coup signaled the end of Sudan's second democratic era, and saw the beginning of Nimeiry's 16 year rule.

The Arab Cold War was a political rivalry in the Arab world from the early 1950s to the late 1970s, as part of the wider Cold War. It is generally accepted that the beginning of the Arab Cold War is marked by the Egyptian revolution of 1952, which eventually led to Gamal Abdel Nasser becoming president of Egypt in 1956. Thereafter, newly formed Arab republics, defined by revolutionary secular nationalism and inspired by Nasser's Egypt, engaged in political rivalries with conservative traditionalist Arab monarchies, led by Saudi Arabia. The Iranian Revolution of 1979 is widely seen as the end of this period of internal conflict and rivalry. Ayatollah Ruhollah Khomeini was installed as the leader of Iran's theocratic government. A new era of Arab-Iranian tensions followed, overshadowing the bitterness of intra-Arab strife.
