What was the idea behind declaring India a democratic country?

The Constitution of India plays an important role for making India a democratic country. It conveys constitutional power and created by a constituent assembly which is accepted by the Indian citizens with a declaration in its preamble.  The Constituent Assembly adopted the Constitution of India on November 26, 1949 and came into effect on January 26, 1950.  This is the reason that the country celebrates January 26 as a Republic Day. 

Basic idea of India declaring as a democratic country:

Due to its adoption and removing the Government of India Act, 1935 which is as the fundamental governing document of the country, the Union of India became the modern and contemporary Republic of India. The Constitution of India defining the fundamental political principles, launches the procedures, structures and duties of the government institutions and exhibit the fundamental rights, directive principles and duties of Indian citizens. In our country every citizen enjoys basic rights such as

• Right to justice
• Right to equality
• Right to freedom
• Right against exploitation
• Right to freedom of religion
• Cultural and educational rights
• Right to privacy
• Right to constitutional remedies

Dr. B.R.Ambedkar was the chairman of the Drafting Committee who wrote the Constitution of India. It is the longest constitution of an independent country in all over the world.  The constitution declares India as a sovereign socialist secular democratic republic, and assures justice for the citizens for equality and liberty. That's why India is declared as a democratic country.
