Question: 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?

<P0-S0> Francis II (Italian: "Francesco II" , christened "Francesco d'Assisi Maria Leopoldo", 16 January 1836 – 27 December 1894) was King of the Two Sicilies from 1859 to 1861. <P0-S1>  He was the last King of the Two Sicilies, as successive invasions by Giuseppe Garibaldi and Victor Emmanuel II of Sardinia ultimately brought an end to his rule, as part of Italian unification. <P0-S2>  After he was deposed, the Kingdom of the Two Sicilies and the Kingdom of Sardinia were merged into the newly formed Kingdom of Italy. <SEP> <P1-S0> 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. <P1-S1>  In the 1890s, the government of Ethiopia began plotting an insurrection in Italian Eritrea to push back against Italian encroachment on their country. <P1-S2>  On December 15, 1894, Bahta Hagos, the "chief of Okule-Kasai province in northern Tigré," launched a rebellion against the Italian authorities. <P1-S3>  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. <P1-S4>  Toselli attacked with 1,500 men, hitting his enemy (who "had almost taken the fort") in the rear. <P1-S5>  Bahta was killed in the ensuing battle and his army fell apart. <P1-S6>  In total, eleven Italians were killed and twenty-two wounded in the action. <SEP> <P2-S0> The Kingdom of Italy (Italian: "Regno d'Italia" ) was a state which existed from 1861, when King Victor Emmanuel II of Sardinia was proclaimed King of Italy, until 1946, when a constitutional referendum led civil discontent to abandon the monarchy and form the Italian Republic. <P2-S1>  The state was founded as a result of the unification of Italy under the influence of the Kingdom of Sardinia, which can be considered its legal predecessor state. <SEP> <P3-S0> The First Italo-Ethiopian War was fought between Italy and Ethiopia from 1895 to 1896. <P3-S1>  It originated from a disputed treaty which, the Italians claimed, turned the country into an Italian protectorate. <P3-S2>  Italy was supported by the two other triple alliance members Germany and Austria. <P3-S3>  Much to their surprise, they found that Ethiopian ruler Menelik II, rather than being opposed by some of his traditional enemies, was supported by them, so the Italian army, invading Ethiopia from Italian Eritrea in 1893, faced a more united front than they expected. <P3-S4>  In addition, Ethiopia was supported by Russia, an Orthodox Christian nation like Ethiopia with military advisers, army training, and the sale of weapons for Ethiopian forces during the war. <P3-S5>  Ethiopia was also supported diplomatically by the United Kingdom and France in order to prevent Italy from becoming a colonial competitor. <P3-S6>  Full-scale war broke out in 1895, with Italian troops having initial success until Ethiopian troops counterattacked Italian positions and besieged the Italian fort of Meqele, forcing its surrender. <P3-S7>  Italian defeat came about after the Battle of Adwa, where the Ethiopian army dealt the heavily outnumbered Italians a decisive blow and forced their retreat back into Eritrea.
