The Iran crisis of 1946, also known as the Azerbaijan Crisis in the Iranian sources, was one of the first crises of the Cold War, sparked by the refusal of Joseph Stalin's Soviet Union to relinquish occupied Iranian territory, despite repeated assurances. The end of World War II should have resulted in the end of the Allied joint occupation of Iran. Instead, Pro-Soviet Iranians proclaimed the separatist Azerbaijan People's Government and the Kurdish separatist Republic of Mahabad. The United States pressure on the Soviet Union to withdraw is the earliest evidence of success with the new strategy of Truman Doctrine and containment.

The Iranian Revolution was a series of events that culminated in the overthrow of the Pahlavi dynasty under Shah Mohammad Reza Pahlavi, and the replacement of his government with an Islamic republic under the Grand Ayatollah Ruhollah Khomeini, a leader of one of the factions in the revolt.

The Persian Revolt was a campaign led by Cyrus the Great in which the province of ancient Persis, which had been under Median rule, declared its independence and fought a successful revolution, separating from the Median Empire.

The Samanid Civil War of 888 was a conflict between the Samanid brothers, Nasr I, ruler of Samarkand and amir of all of the Samanid territories, and Ismail I, who was ruler of Bukhara and Khwarazm. The war took place three years after the Samanid Civil War of 885, which ended with a status quo ante bellum. This time, however, the war ended with a decisive victory for Ismail I. In the aftermath of the war, the victorious brother showed a great deal of respect to his elder and defeated brother and, according to a legend, Ismail even kissed Nasr's hand as a sign of apology. Apparently, Nasr lost much of his power, but he wasn't removed from the Samanid throne; instead, Ismail became de facto ruler of the empire and after death of his brother, he became the amir.

The Sasanian civil war of 589–591 was a conflict that broke out in 589, due to the great deal of dissatisfaction among the nobles towards the rule of Hormizd IV.
