India celebrated its 68th Republic Day on Monday to commemorate the day when the Constitution of the country came into force in 1950, completing its transition towards becoming an independent republic after overthrowing the British colonial government.

While the President Pranab Mukherjee, Prime Minister Narendra Modi and union ministers graced the occasion like always, there were some new things that were showcased during this year's spectacular Republic Day parade which was held at the ceremonial road, called Rajpath (meaning "King's Way") in the country's capital city Delhi.

Here are top 7 highlights from the day:
