The Plaza de toros El Progreso disaster was a crowd collision tragedy that occurred about 8:30 p.m. on 31 January 1965 when in the tunnel and crew ramp of the venue, through which the people who had enjoyed the evening show of Mexican popular music were coming out and at the same time the public who would attend the night show were trying to enter.[1]
