Juan Manuel de Rosas
The United Provinces of Rio de la Plata at the time were being unified by the dictator Juan Manuel de Rosas and tried to recover the Uruguayan territory (Platine War), not excluding also the possibility of aid to the Riograndense separatists. Juan Manuel de Rosas, the Argentine dictator, offered support so that David Canabarro continued the fight. Juan Manuel de Rosas was removed from power in Argentina in a confrontation involving Brazilian troops.
