The plot of The Inca of Perusalem is set in an exaggerated historical context, where the last ruler of the Inca Empire, now living in exile in Europe, is invited to a grand event by the British aristocracy. The "Inca" of the title is an absurd character, dressed in elaborate and outdated regalia, whose status as an emperor is largely symbolic. His role in the play serves as a metaphor for the decay of once-powerful empires and the absurdity of colonialist ideals. The Inca’s interactions with the British elite expose the pretensions of European aristocrats and their misguided notions of grandeur, civilization, and superiority.The play uses humor and irony to critique the absurdities of imperialism, portraying the Inca not as a noble leader, but as a relic of a bygone era who is unable to reconcile the glories of his past with the present reality. Shaw also satirizes the British aristocracy, showing how they cling to outdated notions of cultural and racial superiority, while being indifferent to the actual conditions of the world around them. The play subtly suggests that the self-importance of the Inca and the British aristocrats is a form of illusion, and neither group is truly in touch with the realities of modern society.
