Lords of Middle-earth, Volume II, subtitled "The Mannish Races", is a supplement published by Iron Crown Enterprises (I.C.E.)
in 1987 for the fantasy role-playing game Middle-earth Role Playing (MERP), itself based on the works of J.R.R.
This was followed by a large number of supplements, including a series of three books describing every named character that appears in Tolkien's Middle-earth works.
The first of these was Lords of Middle-earth, Volume I: The Immortals (1985), and the second was Lords of Middle-earth, Volume II: The Mannish Races, a 112-page softcover book designed by Peter Fenlon, with cover art by Angus McBride and interior art by Liz Danforth.
