Despite his extreme youth, he was the candidate proposed by Empress
Mentewab, his grandmother, who then acted as his regent. Her proposal was supported by the great nobles of the reign,
Ras Wolde Leul her brother,
Waragna,
Ayo governor of
Begemder, and
Ras Mikael Sehul. One handicap with this tactic of ruling through a proxy, as
Richard Pankhurst points out, was that neither Iyoas, due to his age, nor Empress Mentewab, due to her sex, could operate far from the capital city of
Gondar, and relied on Waragna and her brothers to lead many of the military campaigns. The very first challenge to Iyoas' rule, when Nanna Giyorgis rebelled in
Damot out of envy for Waragna's increased influence in the court, had to be suppressed by a force led by Waragna and the Empress' brother
Grazmach Eshte. Another problem grew from Mentewab's arrangement of the marriage of her son to Wubit, the daughter of an Oromo chieftain. Iyasu II gave precedence to his mother and allowed her every prerogative as a crowned co-ruler, while his wife Wubit suffered in obscurity. Wubit waited for the accession of her own son to make a bid for the power wielded for so long by Mentewab and her relatives from
Qwara Province. When Iyoas assumed the throne upon his father's sudden death, the aristocrats of Gondar were stunned to find that he more readily spoke in the
Oromo language rather than in
Amharic, and favored his mother's Oromo relatives over the Qwarans of his grandmothers family, or the Gondarine nobility that had surrounded the Solomonic monarchs since the reign of Fasiledes. His preference of the Oromo only increased when Iyoas reached adulthood. He assembled a Royal Guard with 3000 of that people, and put his Oromo uncles Birale and Lubo, the brothers of Wubit, in command of them. On the death of the
Ras of Amhara province, he attempted to promote his uncle Lubo governor of that province, but the outcry led his uncle Wolde Leul to convince him to change his mind. In 1764
Ras Mikael Sehul returned to the capital city of Gondar, and convinced Iyoas to support
Badi abu Shalukh, the exiled king of
Sennar. Iyoas made Badi governor of
Ras al-Fil along the border with Sennar, and Wolde Leul advised Badi to remain in Ras al-Fil; however the exiled king was lured back into Sennar where he was quietly executed. The anti-Oromo party found their champion in
Ya Mariam Bariaw, the son of Ayo (who had helped to make Iyoas Emperor) and governor of Begemder, and who was supported by
Grazmach Eshte. The
Grazmach was made governor of Damot whose governor, Waragna, had died some years before. However, the
Jawa Oromo inhabiting Damot preferred to be ruled by Waragna's son
Fasil; when
Grazmach Eshte arrived in Damot, he was assassinated and Fasil proclaimed governor in his place; according to Bruce, Iyoas' uncles Birale and Lubo convinced him to confirm Fasil in that position. At this point, Ya Mariam Bariaw's pride led to his losing the governorship of Begemder, replaced by the Emperor's Oromo uncle Birale. Because the governorship of Begemder included being custodian of
Mount Wehni, Ya Mariam Bariaw was horrified at the prospect of an outsider holding this important trust, and is said to have begged the Emperor to instead appoint any other ruler to this post. (Or so a document later published by
Ras Mikael Sehul, and according to Bruce, at the instigation of
Aster Iyasu, the daughter of Empress Mentewab.) Despite the outcry of the non-Oromo elite, and Ya Mariam Bariaw's pledge to stop Birale at the Well of Fernay, Iyoas persisted in his decision, and sent his bodyguard to assist Birale's own followers to assume the government of Begemder. In the
ensuing battle Ya Mariam Bariaw was victorious, but despite his explicit orders that Birale should either be captured or allowed to escape, his opponent was killed. Upon learning this, Ya Mariam Bariaw predicted, "Michael, and all the army of Tigre, will march against me before autumn." == Enter
