As part of Emperor Haile Selassie's modernization efforts, the traditional monarchical regime was reformed through the introduction of the 1931 and 1955 constitutions, which introduced an unitary parliamentary system with two legislative bodies: the Chamber of Senate (Yeheggue Mewossegna Meker Beth) and Chamber of Deputies (Yeheggue Memeriya Meker Beth). Under the 1956 constitution Article 56, no one can be simultaneously a member of both chambers, who meet at the beginning or ending of each session.
