The Communist Party of Sri Lanka (CPSL) is a political party founded in 1943. It aims to establish a socialist society in Sri Lanka through the principles of Marxism-Leninism. The party has historically participated in various coalitions and has influenced labor movements and social policies in the country. The CPSL has faced challenges over the years, including internal divisions and competition from other leftist groups, such as the Janatha Vimukthi Peramuna (JVP). Despite these challenges, the party continues to advocate for workers' rights and social justice, contributing to the broader political landscape of Sri Lanka.
