Osman Mahamuud, also known as Uthman III ibn Mahmud, was a Somali king who led the Majeerteen Sultanate during the 19th century. The Majeerteen Sultanate, established by Somalis from the Majeerteen Darod clan, rose to prominence under Boqor Osman's guidance. Notably, his kingdom entered into agreements with Britain and Italy, with the latter making his realm an Italian protectorate. Both rulers had signed the protectorate treaties to advance their own expansionist objectives and assure the continued independence of their territories. The terms of each treaty specified that Italy was to steer clear of any interference in the sultanates' respective administrations. In return for Italian arms and an annual subsidy, the Sultans conceded to a minimum of oversight and economic concessions. Osman's strategic maneuvering and leadership during this period played a significant role in the political landscape of the region. His legacy is an integral part of Somali history and the interactions between local rulers and colonial powers.

Osman Ahmed, also known as عثمان أحمد, was the fifth and final Sultan of the Geledi Sultanate in Somalia, reigning in the late 19th and early 20th centuries. His rule was marked by a decline in the Sultanate's power, with former allies and subjects claiming independence and religious leaders expanding their influence. Despite these challenges, Osman Ahmed was credited with defending the Rahanweyn territory against invasions from the Ethiopian Empire and the Dervish State. He also played a role in negotiating peace with the Bimaal clan and engaging in battles with the Dervish Army. Osman signed treaties with the Italians, ultimately leading to the incorporation of the Geledi state under direct Italian administration by 1911. Despite the decline of the Sultanate, Osman remained a notable traditional figure in Afgooye until his death in the early 1920s. His reign and the events surrounding it reflect a complex period in Somali history, marked by shifting alliances, conflicts, and the impact of European colonialism.

Osman Taka, a Cham Albanian dancer and enigmatic figure from the 19th century, is best known for the Dance of Osman Taka named after him. Little is known about his early life, but he was a member of the Taka clan of Filiates, renowned for producing Albanian patriot Alush Taka. Osman Taka gained prominence during the mid-19th century and was likely involved in resistance against the Ottomans in the Chameria region, possibly as a kachak or klepht. Some sources link him to the Albanian National Awakening of the late 19th century. Following his arrest in Ioannina, he was sentenced to death by Sultan Abdul Hamid II. When asked for his final wish, he requested to dance. Legend has it that his dance was so captivating that the Ottoman Army's local Albanian gendarmes spared him. However, he was eventually recaptured and executed in Konispol. Osman Taka's legacy lives on through the enduring folklore surrounding his life and the Dance of Osman Taka.
