The British found him very useful when they mounted the Onitsha Hinterland Expedition which brought a huge swathe of territory behind Ọnịcha into the British Empire. As reward for his services, the British recognised him on July 9, 1904 as the Paramount Chief and, consequently, first king of Ogidi.
Walter Amobi is said to have married 62 wives and fathered some 108 children. It is no surprise then that the Amobi family is reckoned as the largest family unit in Ogidi today.
He died in 1925, and his offspring held the traditional stool of the town till 1998, when the people of Ogidi decided that the traditional stool was not the Amobi family heirloom. The throne remained vacant until 2016 when Igwe Alex Onyido (not an Amobi, apparently) ascended the throne.
