Why Do We Remember This Date and Not That One?
Ask any American what happened on September 11, 2001, and the answer comes instantly. Ask what happened on September 12th — or on the many September 11ths before 2001 — and the room goes quiet.
Memory is not neutral. The dates we collectively remember are not simply the most important ones. They are the ones that powerful institutions — governments, media, schools — chose to commemorate, teach, and repeat.
September 11, 1973: a US-backed coup overthrows Chile’s democratically elected president Salvador Allende. Thousands are killed and tortured in the months that follow. It is also a September 11th. It does not share the same weight in American consciousness.
This isn’t a conspiracy. It’s just how cultural memory works. Commemoration requires resources. Resources flow toward events that reinforce national narratives — sacrifice, resilience, unity. Events that complicate those narratives get quietly filed away.
The Holocaust has Yom HaShoah. The atomic bombings of Hiroshima and Nagasaki have August 6th and 9th. But the Armenian Genocide, the Rwandan Genocide, the transatlantic slave trade — their anniversaries exist in history books but not in the shared emotional calendar of most people outside the communities most affected.
Whose pain gets a date on the calendar is, ultimately, a political question dressed up as a historical one.
None of this means we should stop commemorating. Remembering matters. But it’s worth asking, every time a date is marked with ceremony: who decided this one? What was left out to make room for it?
The dates we forget reveal as much as the dates we remember. Sometimes more.
