Love and the particular conceptualisation of love during the Renaissance dominate this play. Love is the driving force behind much of the plot and it motivates many of the characters in their actions.
Love in the play
Love, lack of love, or betrayal in love seems to underpin key moments within the drama.
Love obviously intersects with tragedy in the text, and where there is betrayal or the thought of betrayal in love, then that is where we expect to see disorder and chaos emerge.
Historical context
In the Renaissance, we have to bear in mind that most love that happened did not always happen in the romantic way we might conceive of it now.
Marriages were often arranged or completed for practical purposes, with the hope that love might grow and develop between two people.
In this sense, love was a political decision, about retaining social cohesion and alignments.
Othello and Desdemona
It was not about falling in love in the way we conceive of it now. It was an arrangement.
But Othello and Desdemona’s love seems to be genuine and romantic. Desdemona makes it clear that she loves Othello dearly and is committed to him in Act One Scene Three.
You could argue that her love for Othello must be so strong to go against convention and face the wrath of her father.
Love and chaos
Brabantio most obviously represents the old order and wishes Desdemona to marry upon his recommendation.
Although Desdemona and Othello do seem to have a genuine love, perhaps Shakespeare is suggesting that their union breaks the order because of the chaos that their marriage unleashes.
On the other hand, if it were not for the interference of Iago, their marriage may have continued without difficulty.
Love: Iago and Emilia
Iago is a very solitary figure in the play, and you could argue that no-one seems to genuinely care for him.
Iago'sjealousy and bitterness
Iago is motivated by jealousy over Cassio. You could also argue that he is bitter because there is a suggestion that Emilia has slept with Othello.
Iago's marriage
His marriage to Emilia seems to have failed because the two of them are not close.
In this way, their marriage is political for both of them are in the service of Othello: Iago in his army and Emilia as his wife’s maidservant.
It could be argued that the deeper reason for Iago’s motivation for revenge is his loneliness and lack of love.
Emilia
Emilia is a character who also seems stuck in a loveless marriage.
She has probably followed convention in marrying Iago, but it seems that she has come to understand just how he operates.
When she learns of his machinations she clearly hates him for what he has done.
Their love always however, seemed to be an arrangement with both of them cynical about the way men and women operate.
