Macmillan dictionary tell us that history can be either countable or uncountable, so, for example it is correct to say "a history of the Romans" or "the book provides a comprehensive history of the Second World War," and, although I'm comfortable with this usage of the indefinite article before this word, I'm troubled to figure out whether the following snippet, quoting a comment from History.SE, is proper English or not.
"real reconstruction" is vague: you can't reconstruct a history, and if it is a term of art then it is very obscure. (Link)
As far as I understand, the "a history" there is wrong and it would be better to write "history" or "a story", but I don't know why.
Can anybody explain?
