Four main objectives of India after independence are as follows: 

1. The main objective was to shape entire India as a unified nation despite of its diversities, regions, religions, languages, culture, etc. 

2. India adopted the Parliamentary form of government and its objective was to evolve democratic principles, values and practices in accordance with the Constitution. 

3. Its objective was to ensure the well being of Indian citizens, which the constitution mentioned in its preamble. The principles of justice, liberty, equality and fraternity were adopted to ensure the development of society. India developed effective policy for economic development and removal of poverty and illiteracy. 

4. Just before independence, the British declared that with the end of their rule over India, suzerainty of the British dominance over Princely states would also lapse. This declaration made the entire situation very uncertain, and integration of Princely states was one of the main objectives of India.
