"Prioritätsstreit" is just a german word for a priority dispute, i.e. the question who was the first to come up with calculus, not something to indicate that this would be a priority to the German volk. If my memory serves me right, Leibniz didn't much mind about the whole business.

but why write the german word for it in the english article if it isn't somewhat relevant?

Because Leibniz was German, and thus knowledge of the word's relevance to the topic might be useful in further reading?
