Constitution Day is observed in Iran every August 6, commemorating the events of the Iranian Constitutional Revolution of 1905–1911. This day marks the anniversary of Mozaffar ad-Din Shah Qajar's agreement in August 1906 to establish a majlis (parliament) that would limit the Shah's power, following widespread protests against royal corruption and foreign dominance over Persian resources. Although the current Constitution of the Islamic Republic of Iran was adopted in December 1979, Constitution Day specifically honors the Persian Constitution of 1906. It is not a public holiday, but it serves as a significant observance reflecting on Iran's historical struggle for parliamentary democracy. The day is particularly noted for its connection to the protests that took place in the gardens of the British Embassy in Tehran, where over 10,000 men camped out demanding political reform.
