On June 28th, 1966, the constitutional Argentinian President Arturo Illia was overthrown by a military putsch led by Lt. General Juan Carlos Onganía. The Congress elected in 1963 and all political parties were dissolved. The Rector, the Senate of the University of Buenos Aires (UBA), and the Councils of most of the University Schools severely condemned the putsch, with its implied breakdown of all democratic procedures. On July 29th, the Universities were put under the direct control of the military Government and their autonomy was curtailed. That evening the Federal Police invaded the School of Exact and Natural Sciences (Facultad de Ciencias Exactas y Naturales, FCEN) of UBA, brutally attacking the professors and students who had gathered and taking hundreds into police stations for several days. Similar invasions were perpetrated in the School of Architecture and in the School of Philosophy and Letters (FFyL) of the UBA. The Dean and Vice-Dean of the FCEN and the Dean of the School of Architecture were beaten. This episode, known as the "Night of the Long Sticks" (Noche de los bastones largos, or NBL) has been the object of numerous reports and studies.
