On April 20, 1999, two senior students at Columbine High School, Eric Harris, and Dylan Klebold carried out a mass shooting that resulted in the deaths of 12 students and one teacher, and the injury of 21 others, before both of the perpetrators committed suicide.

The attack began when Harris and Klebold arrived at the school armed with firearms, knives, and bombs. They parked their car in the school’s parking lot and began their assault by setting off a propane bomb in the cafeteria, which failed to detonate properly. The two then walked into the school’s library and began shooting at students who were studying there.

The library was the site of the majority of the casualties, with 10 of the fatalities and many injuries occurring there. Harris and Klebold then moved on to other parts of the school, where they continued to shoot at students and teachers. They also set off several more bombs that they had placed throughout the school.

The attack lasted for about an hour before Harris and Klebold committed suicide in the school’s library. The shooting was one of the deadliest school shootings in American history and sparked a national conversation about gun control, school safety, and the impact of violence in media on youth.

After the shooting, investigators discovered that Harris and Klebold had been planning the attack for over a year. They had created homemade bombs and amassed a large arsenal of weapons. They also kept detailed journals and videos documenting their plans and their desire to inflict as much damage as possible.

The attack on Columbine High School was a tragic event that left a lasting impact on the community and the nation as a whole. It spurred efforts to improve school safety and prevent similar tragedies from occurring in the future.

The motive behind this?

The motive behind the Columbine High School shooting remains a complex and controversial topic, and there is no single definitive answer as to why Harris and Klebold carried out the attack.

However, based on the evidence gathered from their personal journals, videos, and other writings, it appears that the two students were motivated by a combination of factors. They were reportedly social outcasts who felt bullied and rejected by their peers, and they harbored deep-seated anger and resentment towards the school and society in general.

Harris and Klebold also had a fascination with violence and had reportedly idolized previous mass shooters such as the Oklahoma City bomber Timothy McVeigh. They had created a detailed plan for the attack and had hoped to inflict as much damage as possible before taking their own lives.

Some experts have also suggested that mental illness may have played a role in the attack. Harris was diagnosed with psychopathy and Klebold with depression, and it is possible that their mental health issues contributed to their decision to carry out the shooting.

Ultimately, the motivations behind the Columbine High School shooting remain a complex and debated issue, and there is no one clear answer as to why Harris and Klebold carried out the attack.



On April 20, 1999, Eric Harris and Dylan Klebold, two students at Columbine High School in Littleton, Colorado, carried out one of the deadliest school shootings in American history. The attack left 13 people dead and more than 20 others injured before the two perpetrators turned the guns on themselves.


Eric Harris and Dylan Klebold were both seniors at Columbine High School. In the months leading up to the shooting, they had become increasingly isolated and had begun to harbor feelings of anger and resentment towards their classmates and the school. They had also been experimenting with explosives and had been planning the attack for several months.

The Attack:

On the morning of April 20, Harris and Klebold arrived at the school armed with guns, knives, and explosives. They began shooting outside of the school, then entered the building, where they continued to fire at students and staff. They also planted several bombs around the school, some of which detonated, causing additional damage.

The attack lasted for nearly an hour, during which time Harris and Klebold taunted and terrorized their victims. They specifically targeted students who they felt had bullied or mistreated them in the past, but also killed and injured others indiscriminately.

The Aftermath:

The Columbine shooting had a profound impact on the country, and sparked a national conversation about gun control, mental health, and school safety. The tragedy also led to changes in the way that law enforcement and school officials respond to threats of violence.

In the years since the shooting, there have been numerous investigations and analyses of the motives behind Harris and Klebold’s actions. It is clear that they were motivated by a deep sense of anger and despair, and felt that the attack was a way to gain power and revenge against those who they felt had wronged them.

In the aftermath of the shooting, there were also questions raised about the role of violent media and video games in inspiring the perpetrators. While there is no evidence to suggest that violent media directly caused the shooting, the incident did bring renewed attention to the debate over the impact of media on youth violence.


The Columbine High School shooting was a tragic and senseless act of violence that left a lasting impact on the country. While there have been many theories and investigations into the motivations behind the attack, the reasons why Harris and Klebold carried out the shooting remain complex and multifaceted. The tragedy also serves as a reminder of the need for continued efforts to promote mental health, gun control, and school safety in our communities.
