The Order of Liberty, or the Order of Freedom, is a Portuguese honorific civil order that distinguishes relevant services to the cause of democracy and freedom, in the defense of the values of civilization and human dignity. The order was created in 1976, after the Carnation Revolution of 1974 in which the corporatist authoritarian Estado Novo regime of António de Oliveira Salazar and Marcello Caetano was deposed. The Grand Collar can also be given by the President of Portugal to former Heads of State and others whose deeds are of an extraordinary nature and particular relevance to Portugal, making them worthy of such a distinction. This can include political acts, physical acts of defense for Portugal, or the good representation of Portugal in other countries.

Mário Alberto Nobre Lopes Soares was a Portuguese politician, who served as prime minister of Portugal from 1976 to 1978 and from 1983 to 1985, and subsequently as the 17th president of Portugal from 1986 to 1996. He was the first secretary-general of the Socialist Party, from its foundation in 1973 to 1986. A major political figure in Portugal, he is considered the father of Portuguese democracy.
