Brotherhood of the Higher Realm Army (BOTHRA) is an Islamic group that seeks to purify Islam through violence. They are led by Pakistani cleric Shaykh Ali Tilani, who established the organization in the early 1980's. Most BOTHRA cells are located in northern Pakistan and North America. BORTHA members have purchased isolated rural compounds in North America to live communally, practice their faith, and insulate themselves from western culture.

BORTHA members have attacked a variety of targets that they view as enemies of Islam, including Muslims they regard as heretics. Attacks during the 1980's included assassinations and firebombing across the United States. BOTHRA members in the United States have been convicted of criminal violations, including murder and fraud.
