A slap made loyalty visible—and dangerous

A ruler who struck an adviser during conversation could turn an ordinary exchange into a test with no safe answer. The adviser had to respond in front of the person who controlled their position, while knowing that any reaction might be read as evidence of disloyalty.

Why the test could not give a clear answer

A flinch might be a reflex, not a political judgment. Staying still might signal discipline—or fear. An adviser who protested could be defending personal dignity, but a ruler might interpret the protest as defiance. Because the king decided what each response meant, the test measured less about private loyalty than about how well courtiers could anticipate his expectations.

That uncertainty could itself serve a purpose. Advisers might become more cautious, carefully managing their expressions and words to avoid giving offense. The spectacle also reminded everyone nearby that access to power came with personal risk. But a test built on intimidation could not reliably distinguish faithful counsel from fearful obedience.

The telling detail is that even a flinch could become political: in a court where the ruler controlled the interpretation, the adviser’s body could be treated as evidence before they had a chance to explain it.
