What did Genghis Khan want to accomplish by dividing his empire between his four sons? He wanted to guarantee each son had an equal share of the empire.
He wanted to make daily governing easier and let his sons share power.
He wanted to make sure one of his sons was selected to be the Great Khan.
He wanted to see which son was the strongest and most capable ruler.

Hamlet's fourth soliloquy is probably his most famous one - "to be or not to be."it is rather different from his previous soliloquies because now he is contemplating something that didn't come up before - suicide. he is thinking whether it is worth it to fight to find his father's murderer when in the end all of them are going to die, so why not die sooner than later. he is contemplating if he should go on fighting or just kill himself and end it all, which is why this soliloquy in particular is rather depressing, hesitant, and gives a deeper insight into hamlet's madness.
