1. Biciidyahan (MJ)
2. Maqaabul (OG)
3. Reer Ayaanle (HG)
4. Toljecle (IQ)
are offshoots of Marehan from the last big offensive/defensive reconfigurations that ended or concluded the long civil war that started with the murder/death of Boqor Mohamed Da'ud Abadir.
1. This ending resulted in the defeat of the original Harari leadership that had retreated from Harar to Aussa.
- The Afar, with the Ali Da'aud dynasty in Harar, took over Aussa to make it an Afar Sultanate from then on and in the east the retreating Marehan of Emir Nur Dynasty who had by then lost Aussa after Harar, engaged in the battle that ended the war among themselves since the death of Boqor Mohamed Da'ud.
The different alliances reconfigured and some splintered off to create the bases of Bicidyahan, Maqaabul, Ayaanle, and Toljecle.
They made new Xeers that made bigger Xeers (i. r. Became "reero" that became "qabiilo").
- This is when the Marehan of the Emir Nur Dynasty had moved the administration of Adal to Aussa to begin with and Ali Da'uud Dynasty of Harar City started (which ended with Menelik's capture of Harar).
In that original start of the long civil war which began inside the Marehan of Harar with members of the Marehan sub-clan of Hawlraarsame accused of the assassination of Boqor Mohamed Da'uud, earlier sets of reconfigurations took place that resulted in splintering to make new Xeer as well with other disjointed groups.
Some groups that I suspect formed from this are Habar Awal, the Jiidle/Baadicadde, Amaanle of the NE, and Jidwaaq.
.
- Beginning of the civil war: the death of Boqor Mohamed Da'ud
- Emir Nur Marehan Dynasty moves Adal to Aussa, Ali Daud Dynasty takes over Harar
- Offshoots from Marehan make Habar Awal, the Jiidle/Baadicadde, Amaanle of the NE, and Jidwaaq.
- Emir Nur Marehan Dynasty moves Adal to Aussa, Ali Daud Dynasty takes over Harar
- Conlusion of the civil war, Hussein Yusuf Matan end battle of succession within Marehan
- Afar Tribesman + Ali Daud Dynasty in Harar seize Aussa and end Adal, Emir Nur Marehan Dynasty retreats East to Hawd/Somali plains
- Offshoots from Marehan make bases of Bicidyahan, Maqaabul, Ayaanle, and Toljecle.
- Afar Tribesman + Ali Daud Dynasty in Harar seize Aussa and end Adal, Emir Nur Marehan Dynasty retreats East to Hawd/Somali plains
- Groups A and B reconfigure in myriad of ways to make new Xeer groups ( Somali clans).
What I am saying sounds radical and surprising, but what makes it sound radical and surprising is just hoe understudied and unscientifically critqued Somali clan formation is.
Of course the above is a theory, but I can assure you it's scientifically based hypothesis and not on subjective oral guesswork.
