Napoleon the Little and Napoleon le Petit oleh Victor Hugo

According to Wikipedia: Napoleon le Petit was an influential political pamphlet by Victor Hugo which condemned the reign of Napoleon III, Emperor of the French. Hugo lived in exile in Guernsey for most of Napoleon IIIs reign, and his criticism of the monarch was significant as he was one of the most prominent Frenchmen of the time, and was revered by many. It includes the concept of two and two make five as a denial of truth by authority, a notion later used by George Orwell in Nineteen Eighty-Four. Volumes were smuggled into France (eg. in bales of hay, and between metal sheets as a tin of sardines), read at secret meetings, and hand-copied.
