• E.V. RamaswamyNaicker, also known as Periyar, was not directly associated with the Vaikom Satyagraha. He was a prominent social reformer and leader from Tamil Nadu, known for his efforts against caste discrimination and for social justice.

• The Vaikom Satyagraha primarily aimed to secure the rights of lower-caste individuals to access public roads around the Vaikom Mahadeva Temple in Kerala. These roads were restricted to upper-caste Hindus, particularly Brahmins, while lower-caste individuals faced discrimination and were denied access.

• The successful culmination of the Vaikom Satyagraha led to the opening of three out of the four roads surrounding the temple for people of all castes. However, one road remained reserved exclusively for Brahmins, reflecting the partial success of the movement in challenging caste-based discrimination.
