He hailed from the village of Kadidal in the nature rich Tirthahalli taluk of Shimoga district from a Vokkaliga Community.^[1] He did his graduation from the Maharaja's College, Mysore and obtained his law degree from the Poona Law college.

Manjappa was a freedom fighter and a true Gandhian who led many struggles in the state for probity in public life.^[2] He served as a minister in various central and state governments for 32 years. He played an important role in initiating land reforms in the early 1950s by introducing laws related to the abolition of absentee landlordism and recognition to the right of cultivators. He is remembered for introducing the Tenancy Act. Several other progressive acts like the Inam abolition act came into being because of vision.
