John Henry Tunstall (6 March 1853 – 18 February 1878), born in
London, England, became a
rancher and merchant in
Lincoln County, New Mexico, where he competed with ethnic Irish merchants and politicians who ran the town of
Lincoln and the county. He was the first man killed in what developed as the
Lincoln County War, an economic and political conflict that resulted in armed warfare, perhaps compounded by ethnic rivalries between an Irish group and others of English descent.
