It is believed that Subhash Chandra Bose was first referred to as "Netaji" by the soldiers of the Indian National Army (INA), which he led during World War II. The term "Netaji" is a Hindi word that means "Respected Leader" or "Respected One," and it was a title of respect and admiration given to Bose by his followers. Bose formed the INA with the help of Japanese soldiers, and with their support, he launched an attack on British-controlled India in 1944. The INA soldiers referred to him as Netaji and it was popularized them. Even though Bose himself never used this title, it was widely used by his followers and supporters, and it became synonymous with his name. The title "Netaji" is a way of showing deep respect and admiration for Bose and his leadership during the Indian independence movement. His leadership and sacrifice for the nation still remain an inspiration for many, and the title "Netaji" is a way of remembering him and his legacy.
