Leftist ideology has been a crucial part of India's political landscape, from revolutionaries like Bhagat Singh to non-violent leaders like Acharya Narendra Dev. The Communist Party of India (CPI) emerged as a significant opposition to Congress post-independence. However, internal splits and challenges eventually led to its decline. In 1964, CPI split to form CPI(M), focusing on mass movements and grassroots politics. Despite initial successes, events like the violent Naxalbari uprising in 1967 and internal disagreements weakened the Left. Leaders like Charu Majumdar broke away to form CPI(ML), initiating a radical, armed movement that divided the Left further. The 1980s and 1990s saw new challenges, including the rise of regional parties, the Mandal Commission's focus on caste politics, and BJP's Hindutva-driven narrative. While the Left remained committed to economic and social justice, it struggled to connect with the middle class and marginalized communities effectively. CPI(M)'s influence peaked in 2004 when it won 43 Lok Sabha seats and supported a Congress-led government. However, their opposition to the India-US nuclear deal in 2008 led to the withdrawal of support, diminishing their national relevance. By 2011, after 34 years of rule in West Bengal, CPI(M) was ousted by Mamata Banerjee's TMC. The 2014 and 2019 Lok Sabha elections saw further declines, and by 2024, Left parties secured only 8 seats nationally, with Kerala being their sole stronghold. The rise of BJP, digital campaigning, and the Left's inability to adapt to modern narratives have left them struggling for relevance. This video explores the journey of Leftist politics in India, its contributions, challenges, and lessons for the future.
