Emperor Haile Selassie, ascending to the throne in 1930, recognized the urgent need for modernization amidst the rise of colonial powers in Africa. By signing Ethiopia's first constitution on July 16, 1931, he took a crucial step in redefining the political landscape of the nation. The constitution aimed to establish a parliamentary system and delineate the powers of the crown, emphasizing the importance of civil liberties and the rule of law. It also marked a significant departure from Ethiopia's feudal past, initiating reforms that would influence the country's governance for decades to come.

The signing ceremony took place in the capital, Addis Ababa, in a newly constructed parliament building that symbolize the new era of governance. The constitution laid the groundwork for a more organized political structure and was an integral part of Selassie's broader efforts to modernize the country, which included expanding education and infrastructure. By embracing constitutional governance, Selassie aimed to strengthen the nation against foreign aggression and to unite diverse ethnic groups within Ethiopia.

Despite these progressive measures, the constitution faced challenges in implementation, exacerbated by political instability and external threats, particularly from Italy. Nonetheless, it stood as a testament to Selassie’s vision for a sovereign and modern Ethiopia, influencing future governance and resistance to colonization.
