Speech 1:
The Republic Day of India is a national holiday of India to mark the transition of India from a British Dominion to a republic on January 26, 1950 and the adoption of the Constitution of India.
Although India obtained its independence on August 15, 1947, the Constitution of India came into effect only on January 26, 1950. During the transition period from 1947 to 1950, King George VI was the head of state. C. Rajagopalachari served as the Governor-General of India during this period. Following January 26, 1950, Rajendra Prasad was elected as the president of India.
A republic is a state or country that is not led by a hereditary monarch. A Republic India signifies the end of British domination on Indian people. This day signifies the power of Non Violence to lead a country to Victory with total Dignity.
Dreams of great people who have fought and sacrificed everything for our country have come true on this day.
This one day is what great people like Gandhi, Bhagat Singh, Lajpat Rai and many more would have loved to see and experience. But now if they would have been alive they would not bear the situation of our country-truth , nonviolence, harmony have faded, we are running blindly towards doom, we are aiming for a lazy life.
My dear friends come Let us begin on this Day a new war for India's Progress, for India's Peace and for India. Let the Revolution begin....

Speech 2:
As soon as we hear the word Republic Day we start looking for an answer to the question that why do we celebrate Republic Day? The answer is on this day our Constitution came into act.
The other question arises, what is the Constitution?
It is legal sanction of the principles by which the country is organized. A preamble is the soul of any constitution and so is ours. Our preamble states that – We the people of India having solemnly resolved to constitute India into a sovereign socialist, secular and democratic republic and to secure all its citizens justices, liberty, equality and fraternity. From this preamble we can get clearly an idea that how the drafting committee though of the people. This committee consisted of Dr. Rajendra Prasad, Dr. B. R. Ambedkar, Jawaharlal Nehru, Sarojni Naidu and 295 other personalities.
Now you would be thinking how are we benefited from the constitution?
So let me throw light to the fact that it has given us the Fundamental Rights and duties by which we are leading a harmonious life. Thus, without a constitution a country is like a body without a soul. I end my speech by paying tribute to those great visionaries who have shaped our democratic India .
