The Bhakti movement is a significant chapter in Indian religious history, which began in South India between the 7th and 10th centuries and later spread throughout the country. Its main objective was to bring about religious reforms across all sections of society. Bhakti means devotion and love towards God. This movement was divided into two forms: Nirguna Bhakti, which involved worship without idols, and Saguna Bhakti, which included idol worship.

Prominent saints of the Bhakti movement include Kabir, Guru Nanak, Tulsidas, Surdas, Mirabai, and Ramdas. Kabir was an advocate of Nirguna Bhakti, and his followers were known as Kabir Panthis. Guru Nanak founded Sikhism and taught principles of equality, monotheism, and opposition to idol worship. Tulsidas authored the Ramcharitmanas, which remains highly popular today. Surdas devoted his poetry to Lord Krishna and composed many devotional songs.

The Bhakti movement opposed the caste system and emphasized the equality of all humans. The saints expressed their teachings in simple language, making them accessible to common people. The Bhakti movement had a profound impact on society and promoted religious and social harmony.
