The area is one of the most historical site of the island as the native village for the famous sultan and poete of the island known as Mbaé trambwe
Mbae Trambwe, a poet, philosopher, and sultan of Washili, left a mark on the history of the Comoros with his eloquence and scholarship.
Mbayé Trambwé, the greatest poet of Grande Comore. He was born in 1735 and died in 1815.
His father is Ntibé Mlanawo wa Mna Aziri of Inya Pirusa, Sultan of Bambao, and his mother M'ma Djamou Wa M'Dombozi of Inya Fwambaya, from Ntsoudjini (some say she comes from Koimbani Oichili). Trambwé spent his childhood in Iconi at the Kaviri Djewé palace with his father until the time when a war broke out between Inya Fwambaya and Inya Pirusa over the territory of Oichili. This war ended with the victory of Inya Fwambaya. Trambwé, being the only descendant of Inya Fwambaya of reigning age, decided to return to Oichili (Koimbani) to take power. He was the greatest poet that Grande Comore has ever known and the principal founder of the Grand Comorian dialect (Shingazidja) thanks to his famous and undeniable proverbs (Nyandu, Shiduwantsi). He was also a man of peace who managed to rule Grande Comore for over 32 years without any conflict. The entrance gate of his palace is called "Goba La Salama" (Gate of Peace), because at that time every community that had a conflict with another was required to come and present its grievances to the royal court in Koimbani (currently Shangani Square or Shanga Trengwe). And he always managed to bring peace to everyone. After his death, the great royal court of the island was transferred to Ntsoudjini at Singani by his successor M'sa Fumu, king of Itsandra.
His annual celebration in Koimbani, Mbae Trambwe Day, has been organized by the Mbae Trambwe Foundation since 1992. This day, established to honor his impact on society, revolves around the theme "Mbae Trambwe and his impact on society." It aims to promote culture, history, and peace, while valuing the "Shikomori" language and Mbae Trambwe's thought.
