1931 Constitution of Ethiopia

The 1931 Constitution of Ethiopia was the first modern constitution for Ethiopia, intended to officially replace the "Fetha Nagast", which had been the supreme law since the Middle Ages. It was promulgated in "an impressive ceremony" held 16 July 1931 in the presence of Emperor Haile Selassie, who had long desired to proclaim one for his country. In the preface to his translation of this constitution into English, William Stern writes, "It is worthy of note that this was the first instance in history where an absolute ruler had sought voluntarily to share sovereign power with the subjects of his realm." This statement, however, is not completely truthful, as the adoption of a constitution was somewhat pressed by international opinion.
In virtue of this constitution, Ethiopia, one of the last absolute monarchies still existing, began the process of constitutionalization of imperial institutions, grounding the Emperor's authority on more solid basis, but also allowing some initial forms of limitation and participation; this evolutive process would continue after World War II with a new constitution. 
Origins and creation.
According to his own autobiography, while still Regent Haile Selassie had wanted Empress Zawditu to proclaim such a document, but "some of the great nobles, to whose advantage it was to rule the country without a constitution, had pretended that it would diminish the dignity and authority of Queen Zawditu if a constitution were set up." Once he became Emperor, Haile Selassie then appointed a commission to draft the document. The commission's leading members included the Europeans Gaston Jèze and Johannes Kolmodin, but most prominently Ethiopian intellectuals such as Tekle Hawariat Tekle Mariyam and Gedamu Woldegiorgis. 
This constitution was based on the Meiji Constitution of Japan, a country that educated Ethiopians considered a model for its successful adoption of Western learning and technology to the framework of a non-Western culture. Unlike its Japanese model, the Ethiopian Constitution was a simple document of 55 articles arranged in seven chapters. It asserted the Emperor's own status, reserved imperial succession to the line of Haile Selassie, and declared that "the person of the Emperor is sacred, his dignity inviolable, and his power indisputable." All power over central and local government, the legislature, the judiciary, and the military was vested in the emperor. The constitution was essentially an effort to provide a legal basis for replacing the traditional provincial rulers with appointees loyal to the emperor. It was not intended to be a representative democracy, as the Emperor alone had the power to designate senators.
According to Haile Selassie, the importance of this legal innovation was not understood "on the side of the officials and the people". To educate them on constitutional theory, he called the leading members of both groups to an assembly where its principal author, Tekle Hawariat, delivered a lengthy speech which not only described the contents of the document, but expounded a theory of constitutional law.
Characteristics.
The 1931 Constitution consists of the Decree proclaiming the constitution and seven chapters divided into 55 articles. The contents of the chapters are:
Application.
A few months later, on 3 November, the anniversary of the Emperor's own coronation, Haile Selassie convened the first parliament of the new constitution. Harold Marcus notes that Emperor Haile Selassie "hoped that the institution would stimulate nationalism and unity and that its members would popularize sociopolitical change in the provinces."
Following the restoration of Haile Selassie in 1941, he re-established the 1931 constitution, convening the parliament on 2 November 1942. This body included a chamber of deputies which was double its pre-war size, who were selected by a combination of an election, held on 9 March 1941, to elect a group of 20 for each of the 12 provinces, who would then meet at the provincial capitals to select five of their members to be deputies.
Despite the resurrection of the parliament, Haile Selassie promulgated a number of laws in the form of proclamations and decrees. It was not until his proclamation 34/1943 that the authority of the parliament was included. Laws were issued under the authority of the Emperor and the parliament until the end of February 1944, when the sole authority of the Emperor again was used, which continued until the beginning of November of that year, when the parliament was again in session.
The Constitution of 1931 was superseded at the time of Emperor Haile Selassie's Silver Jubilee in 1955, when a new constitution was promulgated.
