Beygtach Haji (i.e. saint), a Turkish dervish, founder of religious orders. This pious Mussulman, who, from his virtuous reputation, was called Vely, instituted an order of dervishes, which was called, from the name of the founder, Beygtachis. The reputation which his prophecies and miracles had gained for him determined Amurath I to employ him to consecrate the standard of the new militia. He consented, and, approaching the army, ordered them to conquer in all their undertakings, and gave them the name of Yeni Chery. The tomb of this monk, who died at Querc Chehr in 1367 or 1368, is found at the village of Beyzektach upon the European shore of the Bosphorus, not far from Galata. This is a place of pilgrimage which is highly respected by Mussulmans. See Hoefer, Nouv. Biog. Generale, s.v.
