Shakespeare reveals his preoccupation with fate in Romeo and Juliet through Romeo’s premonition.

Just before he goes to the capulet party where, Romeo and Juliet met and fell in love, Romeo says “For my mind misgives some consequences yet hanging in the stars bitterly begin this fearful date”

This demonstrates the idea of fate because when he says “hanging in the stars”, he is referring to heaven, and thus God’s will.

Another evidence of fate is when friar Lawrence is running to get top Romeo and he falls over. This is an evince of fate because if he did not trip he would of got to Romeo before he killed himself.
