Momoh Jimah Momoh was born on the 2^nd of February 1905 to Momoh the First and the most senior wife, Ovbianogbo. He attended Government School Auchi and exhibited his boldness, creativity, dynamism, progressiveness and uprightness at an early age.  

Momoh Jimah’s leadership qualities shone and he was elevated to hold the title of Dania of Auchi and a deputy to the Otaru in Council. He commanded the formidable age group, popularly known as Umaireghe (those who shake the town), which was a prolific security wing of Auchi at the time of Momoh the First. It was Umaireghe that assisted Momoh the First in ridding Auchi of idols. Through his sterling leadership qualities, Momoh the First prepared him to succeed him on the throne.

M.J. Momoh, though a disciplinarian, was a liberal King who continued to build on the legacies of Momoh the First. He ensured that all the Momoh daughters who were withdrawn from school by Momoh’s puritanical brother returned to school. Otaru M.J. Momoh represented the entire Afemailand at the Western House of Chiefs when he was elected a member of the Western House of Chiefs in 1951. He was highly regarded by neighbouring Kings, even by those older than him. Some milestones recorded during his reign include:

1. Establishment of a postal agency and native court building at Auchi in 1945
2. Textile weaving centre was opened in Auchi in 1945.
3. Post Office was built in 1949
4. Enactment of political consciousness and engagement in Auchi. This was through the activation of Action Group in 1951. Otaru M.J. Momoh and his brother, Prince Kessington Momoh were instrumental to this.
5. Our Lady of Fatima College opened in 1952.
6. Pipeborne water was introduced in Auchi.
7. Uchi Market was established atop the Uchi Hill.
8. Kukuruku Division became known as Afemai (Our Home) which Auchi and most of Etsako West is known by today.

Islam thrived during the reign of Otaru M.J. Momoh. The Islamic schools built by Momoh the First continued to wax strong, and many scholars were trained therein. Towards the end of his reign, construction of the General Hospital in Auchi began in earnest, and free education of Chief Obafemi Awolowo came through in Auchi and many Auchi children benefitted immensely.

He passed on the 7^th September 1955 after ten years on the throne.
