Hassani Arab emirate of southern Mauritania, a Banu Hassan sister-polity to Trarza; the two allied to defeat Nasr ad-Din in the Char Bouba war (1673-77), then fought each other for influence over Waalo and Futa Toro (1720-22); Emir Hamet Mokhtar allied with Abdul Kader's Futa Toro revolution in the 1770s.
Absorbed into French West Africa alongside the other Mauritanian emirates during the early-1900s French pacification of the region (Coppolani campaigns); exact dissolution year not found in a verifiable source and should be treated as approximate.
The atlas holds 5 border frames for Emirate of Brakna — the shape you scrub through changes in 1680 · 1753 · 1799 · 1817 · 1896.
Covers Brakna's origins in the 1673-77 Char Bouba war and its 18th-century rivalry/alliance with Trarza and Futa Toro; used as a verified fallback since no dedicated English monograph on Brakna alone was found.
