The Integration and Development Movement (Spanish: Movimiento de Integración y Desarrollo, MID) is a developmentalist[9] political party founded by Arturo Frondizi in Argentina.

Flying to Caracas, Venezuela in 1956, Argentine wholesaler and publisher Rogelio Julio Frigerio secretly negotiated an agreement between his friend, the centrist UCR's 1951 vice-presidential nominee Arturo Frondizi, and exiled populist leader Juan Perón.

They inherited a difficult economic situation: declining exports and a growing need for costly imported motor vehicles, machinery and fuel, moreover, had caused Argentina to run trade deficits in seven out the past ten years.

Unable to finance these easily, Frondizi's predecessors had resorted to "printing" money to cover the nation's yawning current account deficits, causing prices to rise around sixfold.

Those among Frondizi's former allies who objected to this move backed progressive Buenos Aires Province Governor Oscar Alende, who ran on the UCRI ticket (its last) and finished second; this group later established the Intransigent Party.

Freezing wages for prolonged stretches, deregulating financial markets and encouraging a flood of foreign debt and of imports, the dictatorship's policies helped undo much of what Frondizi and Frigerio had installed twenty years earlier.

[16][17] Allowing elections in 1983, the dictatorship left an insolvent Argentina, its business and consumer confidence almost shattered and its international prestige damaged following the 1982 Falklands War, an invasion Frigerio opposed.
