Sixteen members of an Amish splinter group accused of terrorizing the Amish of eastern Ohio in bizarre beard-cutting attacks are scheduled to go on trial Monday in federal court in Cleveland.

Samuel Mullet Sr., the leader of the breakaway group that prosecutors and former members describe as cultlike, has been charged along with nine other men and six women with multiple counts including conspiracy, hate crimes, kidnapping and destroying evidence.

The assaults on the pacifist, plain-living Amish drew national attention because of their unusual nature — the forcible shearing of men’s beards and women’s long hair, both of which are central to Amish identity.

Former followers of Mr. Mullet also provided lurid details about his domination of some 18 families, many of them his close relatives, in an isolated settlement near Bergholz, Ohio. In a court document filed this month, federal authorities said Mr. Mullet had confined followers in chicken coops for days or weeks to “cleanse” them of impure thoughts or other sins, and had also had adult members hit one another with thick wooden paddles.
