Wikipedia says the Omar Mahamoud, Osman Mahamoud and Isse Mahamoud together form the Mahamoud Saleebaan ([Wikipedia, Majeerteen, backup](https://en.wikipedia.org/wiki/Majeerteen)). See [the Darod tree](/en/society/somali-clan-tree-darod/).

## Main branches

Abbink lists three Omar Mahmoud lines: Reer Khalaf, Reer Hersi and Reer Mahad (Abbink 2009, Darod chart).

ACLED codes these Omar Mahmud groups (ACLED 2025):

| Group | How ACLED codes it |
|---|---|
| Khalaf | Majeerteen > Omar Mahmud > Khalaf |
| Reer Xirsi | Majeerteen > Omar Mahmud > Reer-Xirsi |
| Reer Mahad | Majeerteen > Omar Mahmud Reer-Mahad Mohamed-Muse |
| Bah Yucqub | Majeerteen > Omar Mahmud > Bah Yucqub |
| Reer Abdulle | Majeerteen > Reer Abdulle-Omar Mahmud |

ACLED also codes an "Ali Mohamed-Omar Mahmud" path under the Majeerteen (ACLED 2025). Abbink and ACLED agree on the Khalaf, Xirsi and Mahad lines.

## Where they live

No census counts Somalis by clan. ACCORD notes that Somalis often claim more members than their groups have, "in order to demonstrate strength" ([ACCORD, *Clans in Somalia*, 2009, p. 11](https://www.ecoi.net/en/file/local/1193130/90_1261130976_accord-report-clans-in-somaliarevised-edition-20091215.pdf)).

| Place | What the sources record |
|---|---|
| Northern Mudug | "The north Mudug is mainly inhabited by the Omar Mohamoud ... which is the dominant clan in the area" (EASO 2021) |
| Mudug | "Dominant clans are the Darod (Majerteen-Omar Mahmoud sub-clan) in the North" ([EUAA 2025, Mudug](https://www.euaa.europa.eu/coi/somalia/2025/security-situation/25-galmudug/252-mudug)) |
| Southern Nugaal | The EASO calls the Omar Mahmud dominant "in north Mudug and in the southern part of Nugal" (EASO 2021) |
| Garowe | The EUAA lists Omar Mahamoud among Majeerteen lines living in Garowe ([EUAA Country Focus 2025, Garowe](https://coi.euaa.europa.eu/administration/easo/PLib/2025_05_EUAA_COI_Report_Somalia_Country_Focus.pdf)) |

See [Mudug](/en/regions/mudug/), [Nugaal](/en/regions/nugaal/) and [Puntland](/en/states/puntland/).

## History on record

- **Since 1991.** The EUAA describes Mudug as "divided between Galmudug (Southern Mudug) and Puntland (Northern Mudug)" ([EUAA 2025, Mudug](https://www.euaa.europa.eu/coi/somalia/2025/security-situation/25-galmudug/252-mudug)). See [Galmudug](/en/states/galmudug/).
- **2021.** The EASO listed "[Saad](/en/society/sacad-habar-gidir/) ([Habar Gedir](/en/society/habar-gidir/)) vs Omar Mahamud (Majeerten) in Galkcayo" among northern Mudug rivalries (EASO 2021).
- **December 2024.** Two Majeerteen clans clashed in Xarfo, Mudug. The fighting destroyed a "vital" water well and closed schools ([EUAA 2025, Mudug](https://www.euaa.europa.eu/coi/somalia/2025/security-situation/25-galmudug/252-mudug)).

## Elders and customary law

Senior Somali clan leaders carry titles such as *suldaan*, *ugaas* or *issim*. Their role is "mainly judicial and representative" ([UK Home Office, CPIN Somalia: clans, 2019, quoting EASO 2014](https://www.ecoi.net/en/file/local/2002542/Somalia_-_Clans_-_CPIN_V3.0e.pdf)). See [xeer, Somali customary law](/en/society/xeer-customary-law/).

## In recent conflict records

The EUAA lists these disputes that name the Omar Mahamoud ([EUAA Country Focus 2025, section 1.5.1](https://coi.euaa.europa.eu/administration/easo/PLib/2025_05_EUAA_COI_Report_Somalia_Country_Focus.pdf)):

- Dhulbahante against Omar Mahamoud, in the Adadda area between Nugaal and [Sool](/en/regions/sool/). The two clans "have been feuding for decades".
- Omar Mahmood against Sa'ad (Habar Gidir) in Galkayo and Jiriiban districts. The EUAA calls it "dormant as of February 2025".

See [Dhulbahante](/en/society/dhulbahante/) and [clan conflicts, district by district](/en/society/clan-conflicts/).

## Where sources differ

- **Cross-border.** The EASO's Mudug section has a passage on a clan "found mainly inside the Ethiopian region". Its wording does not make clear whether this means the Omar Mahamoud or another group.
- **Name of the parent line.** Abbink calls it Mahmood. The EUAA and Wikipedia call it Mohamoud Saleebaan.
