The document provides background information on El Filibusterismo, Jose Rizal's second novel written in 1891 as a sequel to Noli Me Tangere. It was written in Spanish and published in Ghent. The novel critiques Philippine society under Spanish colonial rule, depicting the return of the protagonist Crisostomo Ibarra under the alias Simoun to start a revolution in response to abuses. While some characters like Basilio aid the revolution, others like Isagani avert it to save innocent lives. Simoun commits suicide upon being implicated, leaving his jewels with a priest. The novel served as an important reminder of the injustice of colonial oppression and the importance of standing up for rights.
