The Tempest is generally regarded as Shakespeare's last sole-authored play, written around 1610–11. Set on an enchanted island, it explores the nature of power, the ethics of control, and whether forgiveness can genuinely replace revenge — questions that connect directly to Jacobean colonialism and Shakespeare's own relationship with his art.
What is The Tempest about — and why does power matter so much for analysis?
Prospero, the rightful Duke of Milan, was usurped by his brother Antonio twelve years before the action begins and exiled to an island with his infant daughter Miranda. On the island he has enslaved Caliban (the island's original inhabitant) and Ariel (a spirit), using his magic to control both. When his enemies' ship passes near, he raises the tempest of the title to bring them to the island — and then orchestrates every event that follows: Miranda and Ferdinand's love, the conspiracies against Alonso, the drunken plot by Trinculo and Stephano. At the end he forgives his enemies, relinquishes his magic, and prepares to return to Milan.
The word "control" appears in almost every relationship in the play. Prospero controls Ariel, Caliban, Miranda, Ferdinand, and through his magic the island itself. The central analytical question is: does the play endorse this control or interrogate it? The answer is not simply "endorse" — and the most interesting essays hold the tension between Prospero's legitimate grievances and his problematic methods.
What are the key themes?
| Theme | What it explores | Key moments |
|---|---|---|
| Power and control | Who controls whom; whether control is legitimate or tyrannical | Prospero over Ariel, Caliban, and the other characters; the usurpation backstory |
| Colonialism | Prospero's arrival and control as a model of colonial occupation | Caliban's account of being enslaved; his language given to him by Prospero |
| Forgiveness vs revenge | Whether forgiveness is strength or weakness; its conditions | Prospero's choice in Act 5; Ariel's speech about compassion |
| Freedom and slavery | Ariel's yearning for freedom; Caliban's servitude; Miranda's isolation | "This island's mine" (Caliban, Act 1 Scene 2); Ariel's repeated appeals |
| Magic and knowledge | Whether Prospero's power is legitimate; its relationship to art and creativity | The books Prospero values above his dukedom; the "farewell to magic" speech |
| Social order and disruption | Who belongs where; the parallel conspiracies | Gonzalo's utopian speech; the drunkards' plot; the court conspirators |
Who are the key characters?
Prospero is the play's central figure — and one of Shakespeare's most deliberately ambiguous. He is the wronged man seeking justice; he is also the enslaver who refuses Caliban any acknowledgement of the island's prior ownership. His manipulation of everyone on the island, including his own daughter, ranges from benevolent to coercive. His renunciation of magic in Act 5 ("This rough magic I here abjure") is often read as Shakespeare's own farewell to the theatre — a parallel that makes Prospero both more sympathetic and more authorially self-aware.
Caliban is the play's most contested figure in performance and criticism. Prospero and Miranda describe him as savage, monstrous, and inherently evil. Caliban describes himself as the rightful inhabitant of the island: "This island's mine by Sycorax my mother." His claim has full force. Post-colonial criticism (from the 1960s onwards) reads Caliban as a figure for colonised peoples — given the coloniser's language, denied his own, and then condemned as inferior for not fully mastering it. Shakespeare gives Caliban the play's most beautiful speech about the island ("the isle is full of noises"), which sits uneasily beside Prospero's characterisation of him.
Ariel is bound to Prospero by a debt — Prospero freed Ariel from imprisonment by Sycorax. But Ariel's service is also compelled: when Ariel asks for freedom, Prospero threatens punishment. Ariel is the play's most ambiguous spirit figure, neither fully servant nor fully free. Their function in the plot — as Prospero's instrument — also makes Ariel the character through whom many of the play's moral questions about power and obligation are channelled.
Miranda has far less independent agency than most of Shakespeare's female protagonists. She has lived on the island with only her father since infancy and has been educated entirely by him. Her wonder at other human beings ("O brave new world that has such people in't") is genuine and moving, but it is also the product of a severely limited frame of reference. Her relationship with Ferdinand is partly engineered by Prospero, who manipulates them both while pretending not to.
Ferdinand and Gonzalo serve structural purposes: Ferdinand tests the romantic plot (the love between the younger generation as the constructive counterpart to the destructive resentment of the older), while Gonzalo's utopian speech in Act 2 Scene 1 presents an ideal commonwealth that is immediately mocked by the conspirators and never realised — a measure of the gap between idealism and human nature.
What context is essential for high-mark answers?
The Sea Venture shipwreck. In 1609, the Sea Venture, a ship carrying English settlers to Virginia, was wrecked in a storm off Bermuda. The survivors spent nine months on the island before building new vessels and continuing to Jamestown. William Strachey's account of the wreck circulated in manuscript before publication and is strongly believed to have influenced Shakespeare's opening tempest. This historical background connects the play directly to English colonial expansion in the early seventeenth century.
The Jacobean colonial context. The play was written in 1610–11, during the early years of English colonial settlement in Virginia (Jamestown was founded in 1607). Debates about the rights of colonised peoples, whether they could be enslaved, and whether "savagery" was natural or produced by circumstance were live political and theological questions. Caliban's character is directly shaped by these debates.
The court masque. Act 4 Scene 1 contains a masque — a formal entertainment featuring gods and spirits — performed for Ferdinand and Miranda's betrothal. Masques were elaborate, expensive court entertainments associated with James I's court. Prospero's production of the masque figures him as an author-director; its sudden interruption ("Our revels now are ended") when he remembers Caliban's conspiracy produces one of the play's most philosophically rich speeches.
Shakespeare's career and the "farewell" reading. The Tempest was believed for many years to be Shakespeare's final play, written shortly before he retired to Stratford. Many critics and directors have read Prospero's renunciation of his "rough magic" as Shakespeare's own farewell to the stage. Whether or not this biographical reading is historically accurate, it adds a layer of self-referentiality to Prospero's character that is worth acknowledging in analysis.
Frequently asked questions
How should I write about Caliban?
Caliban should be analysed with both available perspectives in view. Prospero and Miranda's reading (savage, monstrous, naturally inferior) was the dominant reading for centuries and should be understood in context — it reflects Jacobean colonial assumptions. The post-colonial reading (Caliban as dispossessed native, given language and then condemned by it) is equally valid textually. Strong essays present both, show where textual evidence supports each, and ask what it means that Shakespeare gives Caliban the play's most poetic speech about the island.
What is the significance of Prospero's books?
Prospero values his books above his dukedom — they are the source of his knowledge and his power. When Antonio usurped him, Gonzalo ensured the books came with him into exile. The books represent the relationship between learning and power: Prospero's mastery of the island derives from study. His final act is to drown his books along with his staff, relinquishing the power they give him. This makes the books both the source of his tyranny and the thing he willingly destroys as part of his moral reckoning.
Is The Tempest's ending genuinely forgiving?
This is one of the play's most productive questions. Prospero forgives his enemies and frees Ariel. But Caliban receives no apology, no restoration of the island, and no acknowledgement that his claim was legitimate — only a grudging "this thing of darkness I / Acknowledge mine." Ariel is freed but has served for years under threat. Miranda and Ferdinand have been manipulated without their knowledge. The ending is not simply warm reconciliation; it is more complicated, and essays that note this complexity are far stronger than those that read it as uncomplicated forgiveness.
How does Prospero relate to Shakespeare himself?
The "farewell to magic" reading — Prospero as Shakespeare, his books as the plays, the island as the stage — is a long-standing critical tradition. The speech "Our revels now are ended" and the Epilogue, in which Prospero/actor directly addresses the audience to be released by applause, both support this reading. Whether you adopt it or treat it as a critical interpretation to consider, it is worth mentioning: many exam boards reward candidates who show awareness of different critical approaches, including biographical ones.
