1580 was a significant year in the resolution of disputes between the Carmelites. On 22 June, Pope Gregory XIII signed a decree, entitled "Pia Consideratione", which authorised the separation of the old (later "calced") and the newly reformed, "Discalced" Carmelites. The Dominican friar Juan Velázquez de las Cuevas was appointed to oversee the decision. At the first General Chapter of the Discalced Carmelites, in Alcalá de Henares on 3 March 1581, John of the Cross was elected one of the "Definitors" of the community, and wrote a constitution for them. By the time of the Provincial Chapter at Alcalá in 1581, there were 22 houses, some 300 friars and 200 nuns among the Discalced Carmelites.
