The famous phrase "Swaraj is my birth right and I will have it" was coined by Bal Gangadhar Tilak, a prominent leader in the Indian freedom struggle during the late 19th and early 20th centuries.
Tilak was one of the first leaders to openly demand complete independence for India from British colonial rule. He believed that "Swaraj" (self-rule) was not only a right but a fundamental birthright of every Indian. The phrase encapsulated his deep conviction that the Indian people had the right to govern themselves, free from British domination.
Tilak used this phrase as a rallying cry to mobilize the masses during the early stages of the Indian independence movement. His fiery speeches and writings were instrumental in awakening nationalistic sentiments among the Indian populace. He was also known for his slogan "Swaraj is my birth right, and I will have it," which came to symbolize the growing demand for independence.
Thus, the correct answer is
Bal Gangadhar Tilak
