The biggest state in the country with over 22 crore population has seen it all--from long spells of President's rule, fractured mandate, mass defections, mid-term elections and withdrawal of support in not so distant past.
Till Mayawati romped home riding on her social engineering formula in 2007 with her BSP getting a clear mandate, the state has experienced frequent bouts of political instability.
The state was placed under President's rule 10 times, the last time being in 2002.
Of the 16 assemblies elected since 1952, a single party got majority and completed full five-year term only seven times. On nine occasions, the state got governments, which lasted for a period as less as four months.
The instability has also led to mid-term elections for seeking fresh mandate as many as seven times, the last being in 1998.
Considered a favourite hunting ground for the Congress in the initial years after Independence with stalwarts from the state leading national and state politics for long years, UP became the first state in the country to get a non-Congress government.
The Congress leaders of Hemwati Nandan Bahuguna's ilk left the party during the Emergency, paving way for President's rule.
Another Congress doyen Kamlapati Tripathi had to quit on the issue of Provincial Armed Constabulary (PAC) revolt in the 70s.
Congress took over the reins in 1980 after the Janata Party's brief spell in power from 1977 to 1980, with leaders of the stature of V P Singh and N D Tiwari at the helm.
But political instability continued to dog the state and the Janata Dal won in 1989.
It was a period of splits, mass defections, hung house, President's rule, mid-term elections and ruling parties flipping chief ministers to quell dissent.
This period saw almost all major parties somehow managing to taste fruits of power, even if for brief spells, while Congress's popularity started waning.
The new non-Congress leadership of Mulayam Singh Yadav, Kalyan Singh, Mayawati and Rajnath Singh among others emerged in the state and they gradually carved out a niche at the national level.
Again in 2012, the emergence of young leadership of Samajwadi Party's Akhilesh Yadav was equally surprising but indicated the desire of the electorate for a stable government.
The 2017 results will prove if UP scores a hat-trick.
