Since independence, Bihar has seen 17 elections, 8 President's rule and 23 Chief Ministers. Satish Prasad Singh holds the record for having the shortest stint as CM. He tenure lasted only for four days - from 28 January 1968 to 1 February 1968. Nitish Kumar holds the record for longest serving CM of the state, he has been in the top office for more than 18 years now.
Krishna Singh was the first CM of Bihar who served the state for more than 13 years - from 15 August 1947 to 31 January 1961. After Krishna Singh, none of the CMs could complete 5-year term until 1990.
This changed when Janata Dal came in power with majority and Lalu Prasad completed his term of 5 years and remained CM from 1990 to 1995. This was the 10th election. Again from 1995-2000, Bihar returned to its old ways - CM's changed, President's rule was imposed. With small blips in-between, Rabri almost completed served for another 5 years - from 11 March 2000 to 6 March 2005.
Then Nitish era began in the state and he has served the state from 2005. In between, Jitan Ram Manjhhi became CM for 278 days and it has been Nitish-raj in the state again after that and it has remained so.
