National integration involves combining all people of a nation into a single whole, binding them together regardless of religion, language or history. It involves sentiments of nationalism, oneness, and cultural, social, political, economic and linguistic unity. November 19th is celebrated as National Integration Day in India, which is also the birthday of Indira Gandhi, India's first female Prime Minister, with the Prime Minister serving as chairman of the national integration council. Obstacles to integration include communalism, provincialism, unemployment, lack of social sense, casteism, political divisions, lack of leadership, frustrated youth, and lack of national character.
