Among the most important events is the military coup in Chile in 1973, which resulted in the fall of President Salvador Allende and the establishment of the military dictatorship of Augusto Pinochet. This event profoundly marked the history of Latin America and had significant international repercussions.
In Portugal, the date of September 11 is also remembered for the worst rail disaster in national history, which occurred in 1985. This railway accident caused a high number of fatalities and left deep scars in the Portuguese collective memory.
The countless events that have marked this date demonstrate how September 11 has become a day laden with historical significance, associating itself with moments of tragedy, violence, and political change in different parts of the world.
