There is considerably richer documentary material, such as correspondence and chronicler's notes on religious books, preserved from the 17th and 18th century, that evidences that Arbanasi reached its economic blossoming between the second half of the 17th and the end of the 18th century. The settlement had over 1,000 houses at the time, its population consisting mostly of eminent merchant families who traded in Transylvania (mostly Sibiu and Braşov), the Danubian Principalities, Russia and Poland. Handicrafts were well-developed, with copper- and goldsmithing, vine-growing and silk production playing an important part. The homes of the rich merchants, as well as the five churches built in the years of progress, bear record of the economic upsurge and prosperity.
