Introduction:
The adoption of the socialist pattern of society in India was a significant development in the country's history. It aimed to establish a more equitable and just society by reducing inequalities and ensuring social and economic justice for all citizens. This adoption of socialism in India had several concomitant factors, which played a crucial role in shaping the country's socio-economic policies and objectives.

Economic Planning:
One of the concomitant factors to the adoption of socialism in India was the implementation of economic planning. The Indian government recognized the need for centralized planning to achieve the goals of socialism. The concept of Five-Year Plans was introduced to guide and regulate the country's economic development, with an emphasis on achieving self-sufficiency, reducing poverty, and promoting employment opportunities. Economic planning aimed to ensure equitable distribution of resources and wealth, reduce regional disparities, and promote social welfare.

Communism:
Communism, as an ideology, also influenced the adoption of socialism in India. The communist movement gained traction in the country, particularly in the pre-independence era. Many leaders and intellectuals were influenced by Marxist ideas and advocated for a socialist revolution. While India did not adopt full-fledged communism, the influence of communist thought played a role in shaping socialist policies and objectives. The emphasis on collective ownership of resources, workers' rights, and the welfare of the working class were central to the socialist pattern of society in India.

Democratic Socialism:
Another concomitant factor to the adoption of socialism in India was the concept of democratic socialism. Unlike communism, democratic socialism emphasizes a mixed economy with a combination of state ownership and private enterprise. It seeks to achieve socialism through democratic means, ensuring political freedom and individual rights alongside social and economic justice. The Indian National Congress, which played a pivotal role in shaping India's socialist policies, advocated for democratic socialism as the guiding principle of the country's development.

Conclusion:
The adoption of the socialist pattern of society in India was marked by concomitant factors such as economic planning, the influence of communism, and the concept of democratic socialism. These factors shaped the country's socio-economic policies and objectives, with an aim to reduce inequalities, promote social welfare, and ensure social and economic justice for all citizens. The adoption of socialism in India was a significant step towards building a more equitable and just society.
