It is a reference to the portuguese king Sebastian, who disapeared at the battle of Alcacer-Quibir in 1578. Since he had no descendence, the portuguese crown went to Felipe II of Spain, thus Portugal effectively lost their independence until 1640. During that time, the myth got started that King Sebastian was only hiding and waiting to return one foggy morning on a glorious white horse, to lead Portugal to its former glory: "o sebastianismo", or sebastianism. The myth is loosely based on a prophecy made by a shoemaker from the town of Trancoso in the early 16th century.
This myth has had an important part in portuguese literature. The national epos "Os Lusiadas" (The Lusiads) by Luis de Camoens is dedicated to king Sebastian (it was written before Sebastian disappeared, Camoens and Sebastian lived in the same era). Later the greatest portuguese poet of the 20th century, Fernando Pessoa, wrote large parts of his masterpiece "Mensagem" (The message) about King Sebastian. More recently, brazilian author Aydano Roriz, as well as luso-american author Deana Barroqueiro have written novels about King Sebastian (2002 and 2007, respectively).
After the Brazilian Republic was declared in 1889, several contestatary movements against the republic were inspired of sebastianism. The most noteworthy were the "Guerra de Canudos" (1897-1898) and the "Guerra do Contestado" (1912-1916). Today, portuguese politicians and intellectuals on ocasion refer to the portuguese economy as sebastianist - i.e. awaiting a magic solution to solve all the problems. The myth was also a big part of the "Fifth Empire" ideology in Portugal, which claimed that the portuguese were chosen to build the universal christian empire.
I have also read that the myth was used by Antonio Salazar to undermine democratic and liberal currents.
I found this short extract of Antonio Pereira Nobre and thought it explained the essence of the myth perfectly
