However, in 1966 the Argentine Government was overthrown in a Coup, replacing Isabel Martínez de Peron with Jorge Rafael Videla, leader of the Militaristic Junta. Whilst this Junta was less than friendly with the Falklands, and cutted many deals, it seemed unlikely that they'd take any action against the Falklands. However, in 1971, Leopoldo Galtieri became the new President of the Junta. Four months into his leadership, his popularity proved to be extremely low, and a plan was hatched to improve public morale.
On the April 2nd 1971, Argentine troops landed in South Georgia, and overthrew the small group of Royal Marines still stationed there.

In 1982 the first free elections for over two decades were held, with Raúl Alfonso elected as President, and promptly reversed Bignone's amnesties. Over the next few years he was to take out democratic reforms, preventing any further coups.

Whilst Spanish remained in official and educational use alongside English, many Argentines emigrated back to the mainland, though many stayed too.
