the sultan that was killed was a usurper, who himself killed another usurper Garaad Abun the relative of imam Ahmed, none of them were atual Walashma sultans, that was a period of politically instability after the legitimate sultan died. As for ifat sultanate, it was not a joke, even Cambridge historians agree that ifat became the largest and most powerful Islamic kingdom in the horn after annexing the sultanate of shewa (ruled by makhzoumi arabs related to khalid ibn walid, the native subjects were argobba), ifat was also the first to declare a religious jihad war against the abyssinian kingdom, many ifat sultans like Arwe Badlay, were capable generals who defeated multiple abyssinian armies, ofcourse they also lost battles, it was an internecine tit for tat war, but walahi it amazes me that ifat sultanate even managed to put up such a long war for nearly 200 years, considering it only involved North Western Somalis (northern Dir, Karanle, and some Darod like Geri, Harti, Marehan, possibly also other samaale clans), these somalis made up less than 45 percent of the total somali population (the rest were in the Warsangali sultanate, and in the southern ajuran sultanate). Despite this huge disparity, they managed to defeat the habashi abyssinians (who also used nilotes, sidamo, some northern oromo, omotic tribes etc) who had a unified kingdom that included their entire ethiosemitic ethnolinguistic group except the harla, while also having multiple other omotic nilotic and cushitic tribes in their armies...compare that to Ifat sultanate that only had a few north western somalis, harla, and some flip flopping argobba Muslims..if Somalis had one kingdom just like the coward habashis, walahi they would've been speaking Somali in Gondar and Metekel today ..our decentralised culture made us lose out on the easy domination and hegemony of the horn prior to this globalised world emerged
