The series of rebellions and riots was resumed in October 1630, when Aslan, deposed Ban of Oltenia, led the local boyars into open revolt, aiming to crown himself Prince. Though this movement also presented itself as nativist to some degree, Aslan was himself a Greek on his father's side; its immediate cause was another tax hike, which had driven the lesser boyars into insolvency.Rezachevici (1978), pp. 73–74, 83–84 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.Rezachevici (1978), pp. 73–74 According to various reports, Catargiu "invaded" land retained by the Craiovești house in Romanați County, splitting the Agas inheritance; as a tax farmer, Matei was also confronted with the massive flight of his fiscal base into the Principality of Transylvania.Rezachevici (1978), p. 74; Stoicescu, pp. 209, 218. See also Mioc, pp. 42–45; Papazoglu & Speteanu, pp. 43–44 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."
