The factors that led to the growth of the Bhakti movement in north India in the 15th and 16th centuries were:

• The people were not satisfied with the old religious practises. They wanted a religion which could satisfy both their reason and emotions.
• There had been a continuous struggle between the Hindus and the Muslims. People were tired of this struggle and wanted to live in peace and harmony with one another. The Bhakti movement paved the way for this.
