Carlos Alberto "Chacho" Álvarez is an Argentine politician. He was Vice President of Argentina during the first 10 months of President Fernando de la Rúa's term, and headed the ALADI Secretariat from 2011 to 2017.

The December 2001 crisis, sometimes known as the Argentinazo, was a period of civil unrest and rioting in Argentina, which took place during December 2001, with the most violent incidents taking place on 19 and 20 December in the capital, Buenos Aires, Rosario and other large cities around the country. It was preceded by a popular revolt against the Argentine government, rallying behind the motto "All of them must go!", which caused the resignation of then-president Fernando de la Rúa, giving way to a period of political instability during which five government officials performed the duties of the Argentine presidency. This period of instability occurred during the larger period of crisis known as the Argentine great depression, an economic, political, and social crisis that lasted from 1998 until 2002.
