India (East Syriac ecclesiastical province)
Metropolitanate of India (Syriac: Beth Hindaye) was an East Syriac ecclesiastical province of the Church of the East, at least nominally, from the seventh to the sixteenth century. The Malabar region (Kerala) of India had long been home to a thriving Eastern Christian community, known as the Saint Thomas Christians.
