Some say, paper was born in Egypt with the appearance of "papyrus", though it was not exactly paper: papyrus was made from compressed reed stalks, not from a pulp. And paper made from a pulp was originally introduced in China and was made from mulberry tree inner bark. Gradually the technology came to America: in 1690 the first paper mill was opened. First paper in Europe, from where it found its way to America, wasn't made from trees: pulp of cotton and linen rag fibers was used.
