Modern history

In 1969 workers and students took to the streets and organized strikes in what has been dubbed the " Rosariazo " against the dictatorship. A few years later, in 1976, the military dictatorship made hundreds of dissident citizens " disappear " in what is known as the Dirty War.

In 1983, Argentina returned to democratic rule, but in 1989, hyperinflation caused the economic collapse of the country. In Rosario there were riots and looting episodes. Under the Menem administration, the situation worsened as the industrial sector of the city was dismantled by foreign competition, and agricultural exports stagnated. In 1995, unemployment in the area reached 21.1% and a large part of Rosario's population fell below the poverty line.

Since the recovery of the national economy that followed the 2001 collapse, Rosario's economic situation has improved. The boom in agricultural exports has caused a large increase in consumer spending and investment. The Socialist Party has won mayoral races in the city in every election since Councilman Héctor Cavallero 's 1989 election. Cavallero's successor, Hermes Binner (elected in 1995), was elected Governor of Santa Fe in 2007 and became the runner-up in the 2011 presidential election on the FAP ticket. Mayor Miguel Lifschitz 's administration, elected in 2007, took advantage of the economic boom to invest heavily in public works as well as in public health (which takes up about a quarter of the whole budget). Mayor Mónica Fein became, in 2011, the first Socialist woman elected mayor in Argentine history.

After the 1990s, Rosario became a major city of the illegal drug trade in Argentina, headed by a drug dealing family called "Los Monos" ("The Monkeys"). Early during 2018, it was estimated by national news sources that a turf war between local drug gangs ("Los Funes" and "Los Camino") was costing an average of one life every twenty five hours.
