Freedom of Speech Day is observed in some Spanish-speaking countries, including Venezuela, Peru, and Uruguay, every September 20. This day celebrates freedom of speech and expression, fundamental human rights in a democratic society. The observance commemorates the anniversary of the capture of Rome on September 20, 1870, which marked the end of papal authority and the transition to democratic values in Italy, including freedom of speech. The event is significant as it symbolizes the establishment of the Kingdom of Italy as a constitutional monarchy. Freedom of opinion and expression is recognized as a human right under Article 19 of the Universal Declaration of Human Rights adopted by the UN General Assembly in 1948. In addition to Freedom of Speech Day, other observances related to this right include World Press Freedom Day on May 3.
