 The Oltenian Matei Basarab, a former "Aga" in the Wallachian military forces, provided Aslan with significant backing, as did other boyars whom Leon had had replaced.According to various reports, Catargiu "invaded" land retained by the Craiovești house in Romanați County, splitting the "Aga"s inheritance; as a tax farmer, Matei was also confronted with the massive flight of his fiscal base into the Principality of Transylvania.Moreover, Leon held boyars "responsible for levying taxes in the territories under their jurisdiction, thus making them liable for those taxes that had to be covered by eventual fugitives from their estates."
