Wow. These are some really insightful ideas and inspiring moments in world and specifically American history. I tend to think, like others, that the most important day in history is connected to a sacrifice, like so many of the days mentioned above. As a Christian, I believe the most important sacrifice which has ever occurred happened on the day Jesus died on the cross for the sins of the world. All the sacrifices of mankind are noteworthy, of course, and I appreciate this trip through some of those world-changing moments.
There are many to choose from - too many really. But I guess I'd say April 9, 1865, the end of the Civil War in the United States and more importantly, the end of slavery. This was a radical departure from our entire history as a nation up to that point, and important progress for humanity.
I think July 4th, 1776 marked one of the most significant days in modern world history. Even though freedom and liberty in 1776 did not apply to all peoples yet, it offered the idea that people had the right to self government. It was the first time in world history that the needs of the many were as worthy as the needs of the one. The fruition of this idea has yet to be attained, perhaps it is unattainable however I believe it to mark a turning point in the human experience. Since 1776 many nations around the world have moved closer to this ideology, that people have the right to be free.
I agree with Ms-mcgregor about both August 6, 1945 and July 7, 1967, but I would also have to say the September 11, 2001 will go down in history as the day we realized that the main conflict of modern history was not to be about economic systems (communism, captialism etc..) but about religious and cultural ideology as Western judeo-christian based democracy came into conflict with Eastern Muslim based totalitarianism.
When we look back many thousands of years, what we find is that people built things to be remembered by. We remember (and can still see) the Egyptian Pyramids and the much younger Roman Coliseum. These structures obviously had much importance to those that built them, and we still marvel at them now. What structures will we leave? If we imagine our distant descendants looking back at us and determining what was important to us, what will they see? The structure that commemorates that important event, that most important day of days, hasn't been built yet; but it will be, and if we're lucky we'll see it in a few more years. But even if we don't see it in our lifetimes, a generation or two from now will be traveling back and forth to it. The first permanent settlement on the Moon, when it is finally in ruins many years after its built, will be the new version of what we consider to be our ancient ruins. But to specify a day to remember a few thousand years from now, when our descendants look back, the single most important day, in whatever calendar they're using, will translate to July 20, 1969.
The assassination of Archduke Ferdinand on June 28, 1914. So much started with that date: modern warfare, socialism, communism, existentialism.
That depends on one's worldview. As a student of history, I would have to pick August 6, 1945, the day the United States dropped the first atom bomb on Hiroshima, Japan. Suddenly, for the first time in world history, mankind now had the ability to totally destroy himself. This weapon, and the more powerful weapons which have followed it, now make another world war unthinkable--or a least horrifically unimaginable. And, until recently it seemed with the balance of power between the United States and the USSR, mankind just might prevent such a disaster. However, with the breakup of the Soviet Union and the rise of terrorism in the world, the nuclear scenario now once again seems possible if we do not find a way to rid ourselves of the nuclear threat.
On the other hand, I also consider June 7, 1967 to be a very important day, religiously. That was the day that Israel retook the city of Jerusalem. On a purely personal level, I consider that day to be the day that restarted the clock towards the second coming of Christ. In a way, both days, to me, seem to dovetail. Mankind enabled himself to destroy his kind on August 6, 1945 and God will come again to prevent that destruction.
Just found this question and string of posts. The first post was 100% on target: it does depend on one's worldview. Frankly, I believe the single most important event in history is the bodily resurrection of the Lord Jesus Christ from the grave. Short answer but a longer explanation. It presupposes there is a Creator God Who not only directly created man in His Image, but that man rebelled and thrust the entire creation and his posterity into sin. It presupposes not only the Fall of man but the Promise of a Redeemer (Genesis 3:15), the Law which convicts men of sin and shows us we are totally incapable of meeting the requirements of a Holy God; a righteous God Who demands justice balanced His love and grace which would provide the perfect Representative to take the penalty, the virgin birth of Jesus, His sinless life, His vicarious/substitutionary death, and God's acceptance and (as well) His approval of both the active and passive obedience of His Son (note that the Jews understood that His claim to be the (sic) Son of God was Jesus' identifying Himself as equal with God (the Father).
"That if thou shalt confess with thy mouth the Lord Jesus, and believe in thine heart that God hath raised Him from the dead, thou shalt be saved." (Roman 10.9)
Fools. The most important day in history, without a doubt, is September 26th, 1983. On this day, a Soviet lieutenant colonel, Stanislav Petrov was on duty when a satellite warning system malfunctioned and warned Petrov of a missile attack. However Petrov (correctly) disregarded the notification as a false alarm. If he had responded to warning as protocol directed him to, he would have notified his Soviet superiors, which would have most likely prompted a nuclear attack on the United States and the rest of the western world. This would have then prompted all out nuclear war and would have likely led the world into a period of nuclear holocaust. All of the days that have been beforehand specified as the most important are, without a doubt, exceedingly important and changed the course of world events, but if Stanislav Petrov had not done what he did, there would be no more world.
ok... so, this may be a little late; but is worth a read.
im pretty sure that the most important day in all of history (as we know it) is sometime in 1439. when gutenberg perfected the printing press; making mass communication possible.
unfortunately, there are too many people who believe everything they read, hear and see. most of which has been manipulated and disfigured by the controlling and well paid hands who control the media today.
and while all other posts have included both amazing accomplishments and horrific tragedies; none would ever have been publicly announced without the beginning and evolution of mass communication.
Was it that warm August day on which Dr King shared his beautiful dream with the rest of the World? August 28, 1963 is the first candidate.
The second is the Moon landing on July 20, 1969.
The third is the nuclear bombing of Hiroshima on August 6, 1945.
Or was it October 12, 1492? July 4, 1776?
February 21, 1848 is the alternative. The whole 1848 year is among the most important in history.
Among the most important dates in American history are also September 11, 2001 and November 4, 2008. No one of us will ever forget those two days.
Wasn't June 6, 1944 one of the most important days in WWII?
And I have to agree when it comes to June 28, 1914, but we shall not forget June 28, 1919, too - Versailles Agreement created the modern Europe as we know it today.
Think about it.
