After a time of relative soundness in the fifteenth century, a succession of occasions shook the Ethiopian realm to its establishments, carrying it extremely close to imploding. To begin with, came an intrusion from the adjoining Muslim Sultanate of Adal (a Muslim state situated in the Horn of Africa, c. 1415 to 1577) drove by a general called Ahmad ibn Ibrahim al-Ghazi whose military plundered and obliterated various houses of worship and Christian masterpieces the nation over somewhere in the range of 1529 and 1543. Invasions by the Oromo individuals from the south all through the sixteenth and mid-seventeenth hundreds of years further stressed the country’s delicate constructions. To exacerbate the situation, the change to Catholicism of Emperor Susanoo’s in 1622 before long dove the country into a common conflict, for a significant number of his subjects would not hold fast to the strict convictions and formal practices that the Jesuit evangelists present in Ethiopia needed to authorize. The contention went on until his resignation for his child Basilides in 1632.
