In what specific context would you use the 'trapassato remoto' tense?

The 'trapassato remoto' (past anterior) tense in Italian is used almost exclusively in formal writing, particularly in historical narratives or literature, to indicate an action that was completed *beforeanother past action, both of which are typically expressed in the 'passato remoto' (remote past) tense. It shows a sequence of events in the past where one action had to be fully finished before the next one began. Essentially, it's the 'past perfect' of the 'passato remoto'. For instance, in the sentence 'Dopo che ebbe finito di parlare, si sedette' (After he had finished speaking, he sat down), 'ebbe finito' is the 'trapassato remoto' and 'si sedette' is the 'passato remoto'. The action of finishing speaking occurred before the action of sitting down. Outside of formal contexts, it's very rare to encounter the 'trapassato remoto' in spoken or informal written Italian; the 'passato prossimo' (present perfect) and 'trapassato prossimo' (past perfect) tenses would be used instead to express similar relationships between past actions.
