I'm sure all of us are familiar with the phrase "Pride comes before the fall." Interestingly enough, this common saying may hold some significant weight according to an article from The Speculator entitled: "On Wall Street, Pride Signals a Fall."

In this article, pride is referred to a hubris which is defined as: "Presumption, originally toward the gods; pride, excessive self-confidence." 

Looking at the world of business, we can see how hubris affects success. When businesses are doing well, their leaders often start to develop hubristic views. The hubris feeling often leads to boasting and a sense of feeling "above the world." This overconfidence and pride is often followed by a drop in business. 
To test this, The Speculator writers looked at magazine covers featuring CEO's and company leaders. Data showed that companies appearing on covers like Forbes and Time started doing worse after the issue was published. If we look at this, it seems to make sense. Someone who agrees to be on the cover of a prestigious magazine most likely thinks highly of themselves and their company. They are full of hubris, and that triggers their decline. The article then goes on to show similar results with companies who purchase stadiums and who start to take over other corporations.
This sense of hubris ties in directly with tragedy. If we consider Oedipus from Sophocles' play, we are shown a clear example of hubris. Oedipus is a powerful king and the savior of his people. He sees himself as a lofty individual, and in his efforts to prove his nobility, he uncovers the secret incest that brings shame upon him. Likewise, his brother-in-law/ uncle Kreon is also full of hubris in Antigone. He is very proud and eager to show his power by punishing Antigone for her crimes. In the end, his confident ways lead to the suicides of both his son and wife.

Hubris has left its mark upon once-successful individuals. Its distinct ability to cause destruction is a good indicator to us all that we need to eat our daily helping of humble pie.
 
There's no surprise in the fact that Antigone, the sequel to Oedipus the King, is a tragedy. It's only fitting that the continuation of such a dark, tragic tale be just as full of suffering and sorrow. 

First off, we have our hero, Antigone. She is a brave girl who represents goodness and virtue.  Antigone is our tragic hero and therefore must make some sort of error. In her case, Antigone's mistake is based on her love for family. She is willing to break the law in order to bury her disgraced brother, and she if noble enough to own up to the crime, even though it means death. In my opinion, Antigone is a strong heroine figure because of her selflessness and compassion. These noble traits make her downfall all the more sorrowful and tragic.

I suppose just a little bit of back story might be helpful in understanding the tragedy of this story. Essentially, Antigone's twin brothers battled it out to see who would be the new king of Thebes. They both killed each other, but because Polyneices was the rebellious brother he was not honored with burial but left to be ripped up by the dogs. Also, Antigone's egotistical jerk-of-an-uncle Kreon decided to enforce the law that if anyone tries to give the body a proper burial, they will be killed.

So all that said, what makes Antigone a tragedy is all the death that takes place because of this in the tragic outcome. First, after she is caught, Antigone is sentenced to die by being sealed in a tomb and left to starve. When Kreon's son Haimon (who is also Antigone's fiancé) hears of this, he breaks into her tomb to rescue her, only to find she has hung herself. In response he kills himself, and then his mother kills herself out of grief. So in short we have one big suicide party going on down at Thebes.  In all seriousness though, I believe this ending is meant to teach the reader specifically about love.
I found this ending rather interesting because it closely relates to one of the most popular tragedies of all time, Romeo and Juliet. In both stories we have two lovers killing themselves when they can no longer be together. The fact that this theme lasted in tragic tradition all the way from Sophocles to Shakespeare shows that love is a strong catalyst in human suffering. Throughout history, the emotion of love has strongly influenced the lives of men and women. What these two works of tragedy may be trying to teach us is that love is a powerful thing that reaches beyond death and sacrifice.
