 After the decline of Latin at the end of the New Latin era started to be perceived, there were attempts to counteract the decline and to revitalize the use of Latin for international communication.In 1815, Miguel Olmo wrote a booklet proposing Latin as the common language for Europe, with the title ("Leisure of Villaudric to the eight great princes who ordained world peace at Vienna in 1815, an extraordinary book about the Latin language and a Latin state to be founded").In the late 19th century, Latin periodicals advocating the revived use of Latin as an international language started to appear.
