Our National Anthem was composed as a poem in December 1911, precisely at the time of the Coronation Durbar of George V, and is a paean in praise of "the overlord of India's destiny". The composition was first sung during a convention of the then LOYALIST Indian National Congress in Calcutta on Dec. 27, 1911. It was sung on the second day of the convention, and the agenda of that day devoted itself to a loyal welcome of George V on his visit to India.
Look at how the event was reported in the Indian press then:
"The Bengali poet Babu Rabindranath Tagore sang a song composed by him specially to welcome the Emperor." (Statesman, Dec. 28, 1911)
"The proceedings began with the singing by Babu Rabindranath Tagore of a song specially composed by him in honour of the Emperor." (Englishman, Dec. 28, 1911)
"When the proceedings of the Indian National Congress began on Wednesday 27th December 1911, a Bengali song in welcome of the Emperor was sung. A resolution welcoming the Emperor and Empress was also adopted unanimously." (Indian, Dec. 29, 1911)
So naturally the poem was more as a praise for the English monarch and acknowledging that he holds the destiny of India. Read the literal english translation of the same...

Rabindranath Tagore is quoted saying "Here is a poem which I have written. It is addressed to God, but give it to Congress people. It will please them."
It pleased them so much that they made it our National Anthem.
