 Third, and related to the previous point, historians are sometimes interested in answering a “how” question: “How did this outcome come to pass? What were the processes through which the outcome occurred?” How did the Prussian Army succeed in defeating the superior French Army in 1870? How did the Polish trade union Solidarity manage to bring about the end of Communist rule in Poland in 1989? Here the pragmatic interest of the historian’s account derives from the antecedent unlikelihood of the event in question: how was this outcome possible? This too is an explanation; but it is an answer to a “how possible” question rather than a “why necessary” question.
