What is a "moor"? What factor is race in this play?

The word Moor refers to the Islamic Arabic inhabitants, having dark skin, in Europe at the time. Othello ascends to the rank of the Venetian military, a city - much like Elizabethan England when the play was written - rife with racism. A general in the army, Othello holds a distinguished place in the Duke's court due to his victories in battle, but not an equal one. He suffers barbs and preconceived notions, yet Othello is esteemed and wins the love of the daughter of a nobleman. However, Brabantio is enraged by Othello's marriage to Desdemona and claims Othello used magic to compel her to run to his "sooty bosom". Race is a factor in the tragedy both in those who seek to destroy Othello, and the victims of the schemes - Othello and Desdemona. Perhaps the most pernicious form of race as an instrument of division is Othello's own view of himself as an outsider, which makes him more susceptible to Iago's plan.
