The Communist Party of India (CPI) is a national political organization advocating Marxism–Leninism and socialism within India’s democratic framework. Established in 1925, it is one of the country’s oldest political parties and a key component of the Indian Left movement, historically active in trade unions, agrarian reforms, and anti-imperialist struggles.Although its parliamentary strength has declined since the 1980s, the CPI remains influential in labor and social movements, particularly in Kerala, Tamil Nadu, and parts of Andhra Pradesh and Bihar. It continues to campaign for secularism, social justice, and resistance to neoliberal economic policies while coordinating with other left parties through the Left Front The CPI was formed by a group of anti-colonial activists inspired by the October Revolution. Its early leaders—such as Manabendra Nath Roy and S. V. Ghate—sought to merge national liberation with a socialist program. Initially banned under British rule, it gained legal status in 1942 and expanded rapidly after independence, advocating land redistribution, women’s equality, and workers’ rights.

The Indian National Congress (INC) is a major political party in India, founded in 1885. It led India’s movement for independence from British rule and became the dominant force in Indian politics for decades after 1947, shaping the nation’s democratic and secular identity.The INC functions through the All India Congress Committee and Pradesh Congress Committees at state levels. Its current agenda emphasizes protecting constitutional values, promoting equality, and fostering sustainable development. Campaigns like the Bharat Jodo Yatra highlight its focus on unity and social harmony Established by Indian reformers and British civil servant Allan Octavian Hume, the INC began as a forum for moderate reform within colonial structures. Under leaders such as Bal Gangadhar Tilak, Mahatma Gandhi, and Jawaharlal Nehru, it evolved into the principal vehicle for India’s struggle for independence. Gandhi’s philosophy of nonviolent civil disobedience transformed the INC into a mass movement culminating in independence in 1947

The Bharatiya Janata Party (BJP) is a major national political organization in India. Established in 1980 as the successor to the Bharatiya Jana Sangh, it promotes a platform of cultural nationalism, economic growth, and strong governance. The BJP currently leads India’s ruling coalition, the National Democratic Alliance, under Prime Minister Narendra Modi.Advocating “Nation First, Party Next, Self Last,” the BJP views national unity and development as intertwined with India’s cultural identity. Its rise has significantly reshaped India’s political landscape, challenging the dominance of the Indian National Congress and influencing debates on secularism, federalism, and national security.  The BJP traces its roots to the Rashtriya Swayamsevak Sangh-affiliated Bharatiya Jana Sangh founded by Syama Prasad Mookerjee in 1951. Its philosophical foundation is Integral Humanism, articulated by Deendayal Upadhyaya, emphasizing a balance between individual, society, and nation. The party espouses “positive secularism” (equal respect for all faiths) and “Antyodaya”—upliftment of the most marginalized.

Rashtriya Janata Dal (RJD) is a regional political party in India, primarily influential in the state of Bihar. Founded in 1997 by Lalu Prasad Yadav, it emerged from a split within the Janata Dal and has since positioned itself as a key voice for social justice and secularism in Indian politics.As of 2026, Lalu Prasad Yadav remains party president, with his son Tejashwi Yadav serving as national working president and principal leader in Bihar. The RJD continues to advocate pro-poor and secular policies, sustaining its role as a central actor in Bihar’s political landscape and a symbol of caste-based social empowerment in India The RJD was established when Lalu Prasad Yadav and several parliamentarians broke away from the Janata Dal to form a party grounded in socialist values inspired by Jayaprakash Narayan. Its central philosophy promotes social equality, economic justice, and protection of minority rights. The party draws much of its support from Other Backward Classes (OBCs), Dalits, and Muslims, advocating an inclusive, secular state.

Janata Dal (United), commonly abbreviated as JD(U), is a center-left political party in India with its primary base in Bihar. It espouses socialism, secularism, and inclusive development and has been a key force in Indian coalition politics, often shaping state and national governments through strategic alliances. As of 2026, JD(U) governs Bihar in coalition with the BJP within the NDA and maintains representation in both houses of India’s Parliament. Its organizational elections and membership expansion continue across several states, positioning it as a pivotal regional actor with national influence JD(U)’s philosophy blends Gandhian and Lohiaite socialism with developmental pragmatism. It emphasizes “Nyay ke saath vikas” (“development with justice”), gender equality, and secular governance. Bihar’s literacy gains, women’s empowerment policies, and social welfare programs under Nitish Kumar have been central to its identity.
