20th century

In 1914 there was an uprising of the natives inspired by the elderly catechist María Angata Veri Veri and led by Daniel Maria Teave with the aim of getting the State to take charge of the situation generated by the company. The Navy held the company responsible for the "brutal and savage acts" committed by Merlet and the company's administrators and an investigation was requested.

In 1916, the island was declared a subdelegation of the Department of Valparaíso. In the same year, Archbishop Rafael Edwards Salas visited the island and became the main spokesman for the natives' complaints and demands. However, the Chilean State decided to renew the lease to the company, under the figure of the so-called "Provisional Temperament", distributing additional lands to the natives (5 ha per marriage as of 1926), allocating lands for the Chilean administration and establishing the permanent presence of the Navy, which in 1936 established a regulation according to which, with prior permission, the natives could leave Hanga Roa to fish or provide themselves with fuel.

Monsignor Rafael Edwards sought to have the island declared a "naval jurisdiction" in order to intervene in it as military vicar and in this way support the Rapa Nui community, creating better living conditions.

In 1933, the Chilean State Defense Council required the registration of the island in the name of the State in order to protect it from private individuals who wanted to register it in their own name.

Until the 1960s the Rapanui were confined to Hanga Roa. The rest of the island was rented to the Williamson-Balfour Company as a sheep farm until 1953 when President Carlos Ibáñez del Campo cancelled the company's contract for non-compliance and then assigned the entire administration of the island to the Chilean Navy. The island was then managed by the Chilean Navy until 1966, at which point the island was reopened in its entirety. The Rapanui were given Chilean citizenship that year with the Pascua Law enacted during the government of Eduardo Frei Montalva. Only Spanish was taught in the schools until that year. The Law also created the Isla de Pascua commune depending from the Valparaíso Province and implemented the Civil Registry, created the positions of governor, mayor and councilman, as well as the 6th Police Station of Carabineros de Chile, the first fire company of Easter Island, schools and a hospital. The first mayor was sworn in 1966 and was Alfonso Rapu who sent a letter to President Frei two years prior influencing him to create the Pascua Law.

Islanders were only able to travel off the island easily after the construction of the Mataveri International Airport in 1965, which was built by the Longhi construction company, carrying hundreds of workers, heavy machinery, tents and a field hospital on ships. However, its use did not go beyond airline operations with small groups of tourists. At the same time, a NASA tracking station operated on the island, which ceased operations in 1975.

Between 1965 and 1970, the United States Air Force (USAF) settled on Easter Island, radically changing the way of life of the Rapa Nui, as they became acquainted with the customs of the consumer societies of the developed world.

In April 1967 LAN Chile flights began to land and the island began to be oriented towards cultural tourism. Since then, the main concerns for the natives were to strengthen production and marketing cooperatives, which received state support, and to recover their communal lands.

Following the 1973 Chilean coup d'état that brought Augusto Pinochet to power, Easter Island was placed under martial law. Tourism slowed down and private property was restored. During his time in power, Pinochet visited Easter Island on three occasions. The military built a number of new military facilities and a new city hall.

On January 24, 1975, television arrived on the island, with the inauguration of a station of Televisión Nacional de Chile, which broadcast programming on a delayed basis until 1996, when live satellite transmissions to the island began.

In 1976 the Isla de Pascua Province was created with Arnt Arentsen Pettersen appointed as the first governor between 1976 and 1979. Between 1984 and 1990 the administration of Governor Sergio Rapu Haoa stands out and since then all the governors have been Rapanui.

In 1979, Decree Law No. 2885 was enacted to grant individual land titles to regular holders.

On April 1, 1986, Law No. 18,502 is enacted, which establishes the special fuel subsidy in Easter Island, stating that it "may not exceed in each product 3.5 monthly tax units per cubic meter, whose value may be paid directly or through the imputation of the respective amount to the payment of certain taxes".

As a result of an agreement in 1985 between Chile and the United States, the runway at Mataveri International Airport was extended by 423 metres (1,388 ft), reaching 3,353 metres (11,001 ft), and was re-opened in 1987. Pinochet is reported to have refused to attend the opening ceremony in protest against pressures from the United States to address human rights cases.
