Parliamentary elections were held in Portugal on 28 November and 12 December 1847.[1]
The elections were held under the Constitutional Charter of 1826,[2] and in accordance with a decree issued on 12 August 1847.[1] Members of the Chamber of Deputies were elected in an indirect system in which voters elected provincial assemblies, who in turn elected members of the Chamber.[2]
The 142 members of the Chamber of Deputies included 119 representing the mainland and 10 representing islands (all elected in multi-member constituencies), with another 13 representing overseas colonies (three elected in single-member constituencies and ten in multi-member constituencies).[1]
Supporters of the Patuleia boycotted the elections.[1]
