Imperia is a statue at the entrance of the harbour of Konstanz, Germany, commemorating the Council of Constance that took place there between 1414 and 1418.

The erection of the statue caused controversy, but it was on the private property of a rail company that did not object to its presence.

Although the two men resemble Pope Martin V (elected during the council) and Emperor Sigismund (who called the council), and they wear the papal tiara and imperial crown, Lenk has stated that these figures "are not the Pope and not the Emperor, but fools who have acquired the insignia of secular and spiritual power.

The story is a harsh satire of the Catholic clergy's morals, where Imperia seduces cardinals and princes at the Council of Constance and has power over them all.

The historical Imperia that served as the source material of Balzac's story was a well-educated Italian courtesan who died in 1512, nearly 100 years after the council, and never visited Konstanz.
