In 1813-14 Rich spent some time in Europe, and on his return to Bagdad devoted himself to the study of the geography of Asia Minor, and collected much information in Syrian and Chaldaean convents concerning the Yezidis.
Of these, 126 monasteries and 90 convents were situated in the city, 51 monasteries and 22 convents in the suburbicariates.
The law of 1873 created a special charitable and religious fund of the city, while it left untouched 23 monasteries and 49 convents which had either the character of private institutions or were supported by foreign funds.
The proceeds of the sale of the suppressed convents and monasteries were partly converted into pensions for monks and nuns, and partly allotted to the municipal charity boards which had undertaken the educational and charitable functions formerly exercised by the religious orders.
In exempt convents the head of the monastery or priory exercised jurisdiction subject to an appeal to the pope.
