The terminology differs between Nuclear Physics and High Energy Physics.

NP says "history" (c.f. MCNP, SCALE) where HEP says "event" (c.f. Geant4, Root).

In HEP and Geant4, generally there is a single primary particle per event, so event = history. Generating multiple primary particles in a single event is unusual, because those primary particles will interact independently, and the term "event" is intended to represent what happens to one of them. But if you do that, then what you say is the closest translation between these terms.
