What state existed from 1861, when King Victor Emmanuel II of Sardinia was proclaimed King of Italy, was the subject to the plotting of  an insurrection in Italian Eritrea by the government of Ethiopia?
Battle of Halai The Battle of Halai, or the Battle of Halay, which took place in December 1894, was one of the opening battles of the First Italo-Ethiopian War. In the 1890s, the government of Ethiopia began plotting an insurrection in Italian Eritrea to push back against Italian encroachment on their country. On December 15, 1894, Bahta Hagos, the "chief of Okule-Kasai province in northern Tigré," launched a rebellion against the Italian authorities. On December 18, a force of Italian troops, led by Major Pietro Toselli discovered that a small Italian fort at Halai (garrisoned by 220 men) was being besieged by 1,600 of Bahta's rebels. Toselli attacked with 1,500 men, hitting his enemy (who "had almost taken the fort") in the rear. Bahta was killed in the ensuing battle and his army fell apart. In total, eleven Italians were killed and twenty-two wounded in the action.
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."
