Convocation

Convocation, an assemblage of the English clergy, with little or no legislative power, summoned and prorogued by an archbishop under authority of the Crown; one under the Archbishop of Canterbury, held at Canterbury, and one under the Archbishop of York, held at York, consisting each of two bodies, an Upper of bishops, and an Under of lesser dignitaries and inferior clergy, in separate chambers, though they originally met in one.
