'Jana Gana Mana', the country's national anthem penned by Nobel Laureate Rabindranath Tagore, turned 100 today as it was first sung on this day a century ago at the 1911 Calcutta Session of the Indian National Congress.

Written in highly Sanskritised Bengali in 1911 by one of the greatest poets of the 21st century, the song has fired patriotism in every Indian during the Independence movement.
