When we look at Shakespeare's "Othello" we see several themes that underlie the whole play from beginning to end. It is certainly not hard to conclude that it is probably Shakespeare's most controversial play. There is a clear theme of racism throughout, one which was firmly embedded in the Venetian society which rejects the marriage of Othello and Desdemona as erring, 'against all rules of nature,' [1.3.102] Nothing separates Othello from, 'the wealthy curled darlings of our nation,' [1.2.68] except skin-color - he matches or even exceeds them in reputation.
