A trusted ensign, passed over for promotion, talks a great general into murderous jealousy of his own faithful wife, then watches the ruin he engineered.

Mental models
Iago's power comes from reputation. He is called honest so often that his word outweighs the evidence of those telling the truth. Credibility, once granted, is hard to revoke.
It is a reminder to weigh claims by their substance rather than by the standing of the person making them, since trust can be the very channel through which deception travels.
Iago rarely accuses. He hints, hesitates, and warns Othello against jealousy, letting Othello complete the thought himself. The victim feels he reached the conclusion on his own.
It exposes a method of manipulation: an idea a person assembles for themselves is held more firmly than one they were simply handed.
The handkerchief means nothing on its own, but once Othello is primed to suspect, the object becomes the confirmation he wanted. Meaning is supplied by the watcher, not the thing.
It warns that someone braced to believe the worst will read intention into neutral details, so a single planted item can stand in for evidence that does not exist.
Summary
Othello is a tragedy of a manufactured jealousy. Iago, ensign to the Moorish general Othello, has been passed over for promotion in favor of Cassio, and he opens the play already resolved to destroy his commander while wearing the face of a loyal servant. His first act is to rouse Desdemona's father against her secret marriage to Othello.
Othello answers the charge of bewitching Desdemona by describing an honest courtship: she loved him for the dangers he had passed, and he loved her for the pity she gave them. The Venetian state, needing him against the Turks, sends him to govern Cyprus, and Desdemona insists on following. For a moment the marriage stands clear and strong, with the threat removed before any battle.
On Cyprus, Iago begins his real work. He engineers a drunken brawl that costs Cassio his lieutenancy, then advises Cassio to seek Desdemona's help in winning it back. With Cassio always at her side pleading, Iago has only to drop hints to Othello and to caution him against the very jealousy he is provoking. He never makes a direct accusation; he lets suspicion do its own growing.
Othello demands proof, and Iago supplies the appearance of it: a handkerchief, Othello's first gift to his wife, picked up after she drops it and planted in Cassio's room. Around this single object Iago builds a story Othello is now desperate to believe. The general's language darkens, his trust in Desdemona collapses, and he resolves to kill her for an offense she never committed.
The end gathers in a single night. Othello smothers Desdemona in their bed, still loving her as he condemns her. Emilia, Iago's wife, exposes the lie of the handkerchief and is killed by Iago for it. Learning the truth, Othello kills himself, asking only to be spoken of as one who loved too much and was too easily worked upon. Iago, captured, refuses to explain himself and is left to punishment.
