20th Century
The territory of Inini, consisting of most of the interior of French Guiana, was created in 1930. It was abolished in 1946.
During World War II the local government declared its allegiance to the Vichy government, despite widespread support for Charles de Gaulle. This government was later removed by the Free French Forces in August 1944.
French Guiana became an overseas département of France on 19 March 1946.
The infamous penal colonies, including Devil's Island, were gradually phased out and then formally closed in 1951. At first, only those freed prisoners who could raise the fare for their return passage to France were able to go home, so French Guiana was haunted after the official closing of the prisons by numerous freed convicts leading an aimless existence in the colony.
Visitors to the site in December 1954 reported being deeply shocked by the conditions and the constant screams from the cell-block still in use for convicts who had gone insane and which had only tiny ventilation slots at the tops of the walls under the roof. Food was pushed in and bodies removed once a day.
In 1964 Kourou was chosen to be launch site for rockets, largely due to its favourable location near the equator. The Guiana Space Centre was built and became operational in 1968. This has provided some local employment and the mainly foreign technicians, and hundreds of troops stationed in the region to prevent sabotage, bring a little income to the local economy.
The 1970s saw the settlement of Hmong refugees from Laos in the county, primarily to the towns of Javouhey and Cacao. The Green Plan (Plan Vert) of 1976 aimed to improve production, though it had only limited success. A movement for increased autonomy from France gained momentum in the 70s and 80s, along with the increasing success of the Parti Socialiste Guyanais.
Protests by those calling for more autonomy from France have become increasingly vocal. Protests in 1996, 1997 and 2000 all ended in violence. While many Guianese wish to see more autonomy, support for complete independence is low.
