{{APIRef("History API")}}

PopStateEvent is an interface for the {{domxref("Window/popstate_event", "popstate")}} event.

A popstate event is dispatched to the window every time the active history entry changes between two history entries for the same document. If the history entry being activated was created by a call to history.pushState() or was affected by a call to history.replaceState(), the popstate event's state property contains a copy of the history entry's state object.
