The Khordad Movement Anniversary is observed in Iran on June 5 each year, commemorating a significant event in the country's history that took place in 1963. This movement emerged as a protest against the imprisonment of Ayatollah Ruhollah Khomeini, a prominent political and religious leader who opposed the Shah and criticized the United States and Israel. Khomeini's arrest followed a speech in which he likened the Shah, Mohammad Reza Pahlavi, to the tyrant Yazid I, prompting widespread demonstrations across Iranian cities. In response, the Shah declared martial law and imposed a curfew to restore order. While official reports indicate that 380 people were killed or wounded during the protests, the true number is likely higher due to unreported casualties. The anniversary serves as a reminder of the historical struggle for political and social change in Iran.
