The Kerala Congress (Jacob) faction was born in 1993 when T. M. Jacob and his supporting MLAs - Johnny Nellore, Mathew Stephen and P. M. Mathew - decided to split from the Kerala Congress (M) party led by former Minister K. M. Mani following difference of opinion.
Kerala Congress (Jacob) has its strongholds in the eastern part of Ernakulam district, such as Piravom, Muvattupuzha, Kothamangalam, Angamaly and Kuthattukulam, and in certain areas in the Kannur, Alapuzha, Kollam, Idukki, Thrissur and Trivandrum districts.
