Hi I would like to learn about Kolkata what can you tell me? 
 During the 1980's Mumbai overtook the title of the most populated city in India. Before this Kolkata was considered the most populated. 
 Interesting, what else can you tell me about their history? 
 Between 1977-2011 Kolkata governed West Bengal by the Left Front. It was dominated by the Communist Party of India. 
 Please, tell me more about their history 
 The Left Front was defeated by the Trinamool Congress in 2011 during the West Bengal Legislative Assembly election. 
 Thank you. Can you please tell me about their etymology now? 
 You're welcome. Kolkata is thought to be a variation of Kalikkhetro which means "Field of Kali" (the goddess). 
 Wow that's cool. Do you have any other facts on Kolkata's etymology?
