ETAN was founded in 1991 to support the right to self-determination of Timor-Leste. In 2001, that goal was significantly realized when the people of East Timor voted for independence. Since then ETAN has focused on building on its success in support of justice and self-determination in Timor-Leste and the surrounding region.
