I've long considered writing a historical fiction series.
First book: Amde Seyon's conquest of most of the Horn, and the desperate coalition to oppose him culminating in the Battle of Das where the last resistance to his rule is crushed.
Second book: The simmering rebellion against the Empire, begins to rise after the death of Amde Seyon and the enthronement of his son Newaya Krestos, who takes the throne name Sayfa Ared the Sword of Terror, who marches on Egypt and forces the Mameluke sultan to release the jailed Patriarch of Alexandria. Sayfa Ared supresses all the revolts against his rule by brutally suppressing them and imprisons all the heirs to his vassal kingdoms in his court. Book ends with the birth of Saadadiin and the death of Sayfa Ared at the imperial court.
Third book: The new emperor Dawit enters into a power struggle against Ifat culminating in Saadadiin rebelling against imperial rule. Everyone expects Ifat to be crushed but surprizingly Saadadiin defeats the imperial army and kills Emperor Dawit. Dawit's son and heir Tewodros takes the throne as Walda Anbasa the Son of the Lion but is killed less than a year later leading another army against Saadadiin. This frees up the throne for Dawit's younger son Yeshaq, who is a military genius. Despite most of the army having been destroyed and Adal now leading a huge army of Muslim rebels from across the empire, Yeshaq wins several lopsided battles and marches on Zeila, wiping out Saadadiin's whole army and the Ifat royal family flees to Yemen.
Fourth Book: Yeshaq reconquers the empire of his great-grandfather and brings in Egyptian military advisors, and tries to establish an anti-Muslim alliance with the kingdom of Aragon. Meanwhile in Yemen the sons of Saadadiin prepare to retake their homeland, making landfall in their homeland. One after another Yeshaq kills them in battle, first Sabraddiin then Mansur, and finally crushed the forces of Jamaluddiin but he was mortally wounded in the battle with Jamaluddiin and died. With Yeshaq dead, the last son of Saadadiin, Ahmedudiin turns the tide and defeats the Empire in many important battles and drove them out of the Ahmar Mountains and captured Bale. Ahmedudiin invades Dawaro but is killed by Emperor Zara Yacqob. Exhausted from war, a de-facto armistice takes hold.
Fifth Book: Fifty years have passed and the uneasy peace is broken with Mahfuz invading Dawaro, leading to the assassination of Sultan Mohamed and civil war in Adal. The rise and fall of many sultans leads to the rise of Ahmed Gurey, who wins the civil war and leads an invasion of the Empire.
