Flattery
Flattery (also called adulation or blandishment) is the act of giving excessive compliments, generally for the purpose of ingratiating oneself with the subject.
Historically, flattery has been used as a standard form of discourse when addressing a king or queen. In the Renaissance, it was a common practice among writers to flatter the reigning monarch, as Edmund Spenser flattered Queen Elizabeth I in The Faerie Queene, William Shakespeare flattered King James I in Macbeth and Niccolò Machiavelli flattered Lorenzo II de' Medici in The Prince.
