The phrase "11 sep feriado" is a Spanish term that functions as a proper noun. In this construction, "feriado" is the noun, meaning "holiday" or "public holiday." The preceding date, "11 sep" (September 11th), acts as a specific adjectival designator, identifying which holiday is being referenced. Therefore, the entire phrase names a specific, singular event: the September 11th holiday.
This term refers to a public holiday historically observed in Chile to commemorate the coup d'tat of September 11, 1973. On that date, the democratically elected government of President Salvador Allende was overthrown by the Chilean armed forces, led by General Augusto Pinochet. The event initiated a 17-year military dictatorship and remains one of the most significant and divisive moments in modern Chilean history.
The observance of this date as a "feriado" is highly controversial and reflects deep political and social divisions within Chile. For supporters of the Pinochet regime, the day represents national liberation from a socialist government. For opponents and victims of the dictatorship, it is a day of mourning that marks the loss of democracy and the beginning of widespread human rights abuses. Consequently, the legal status of the holiday has been subject to political debate and has changed over time, often being enacted or repealed depending on the political orientation of the government in power.
