Read the full account

La Scala heritage and Britannica date Un giorno di regno’s unsuccessful 5 September 1840 premiere. Impresario Merelli and singers share the night. Later triumphs are not this flop.

Context

Family deaths earlier in 1840 are neighbouring. Nabucco 1842 is a later recovery row.

Giuseppe Verdi’s documented role is bounded by other offices and collaborators named in the sources below.

Merelli’s seasons; Verdi asked to be released from contracts after the disaster.

Why it matters

A premiered failure is a labour-market tightness path for a working composer.
