Soon after becoming king in 1928, Nigus Taffari recieved yet another challenge from the forces of conservatism. Dejazmatch Balcha Saffo, had briefly succeeded Dejazmatch Yilma Makonnen as governor of Harrar, but upon his replacement by the then Dejazmatch Taffari in 1910, he had been appointed Governor of the wealthy gold, ivory and coffee producing province of Sidamo.
Now he arrived in Addis Ababa from Sidamo with a very large number of well armed men. He had repeatedly refused the summons of the new King to come to the Capital, and only obeyed now because he had recieced a summons from the Empress.
Dejazmatch Balcha and his army encamped at Nifas Silk, just outside the city, and the presence of Balcha's large Army was regarded as being a direct challenge to the king, in support of the Empress and the conservatives she supported.
On the second evening after his arrival, Dejazmatch Balcha and his leading officers were invited by King Taffari to come to the Imperial Palace for dinner. They arrived to find a fine feast prepared for them, and much to drink.
As the evening wore on, and Balcha's officers grew more and more intoxicated, they also grew more and more insulting to the king and his supporters as they sang songs as was customary.
When the Dejazmatch and his followers finally returned to Nifas Silk, they were stunned to find that his entire army had vanished. While they had been eating and drinking at the palace, Ras Kassa Hailu and several other officials had arrived at Nifas Silk with a bag of Silver Maria Theresa Thallers, and another bag of whips.
They announced to Balcha's army that a new governor, Ras Birru, had been appointed for Sidamo and that they were to report to him at once.
They were instructed to immediately accept payment in the silver coins, surrender their weapons and go home. The bag of whips was left in clear view to show what would happen to anyone who did not obey.
Within a short time, the soldiers had surrendered their weapons, recieved their payment and were headed back to their farms and families in the south. When Dejazmatch Balcha realized what had happened he fled to the Raguel Church on Mt. Entoto and rang the bell, a traditional plea for royal mercy in Ethiopia that monarchs were required to honor.
The King confined Balcha to a monastery, but did not punish him further.
Death
When Italy invaded in the Second Italo-Abyssinian War, Balcha Safo came out of retirement to fight against the Italians. Major Mesfin Seleshi, an agent of the imperial government in exile who was coordinating resistance in occupied Ethiopia, writes of his fate in a letter to Haile Selassie I thus:
"The enemy went as far as Gurage, where his Excellency Dejazmatch Balcha lives, and campaigned against him. The people betrayed him, and all his men were annihilated. He and two of his servants, three people all together, were surrounded. A white man came to him and asked, are you Dejazmatch Balcha? When he said yes I am, the white man said, surrender your arms, and untie your pistol [belt]. Dejazmatch Balcha said, 'I am not here to surrender my arms', and he killed the white man; then, he and his two servants died instantly without having much suffering."
