British India (officially known as the Indian Empire) had various flags incorporating the Union Jack. The Star of India was the flag used for most official purposes. The Flags included the Union Jack defaced with the Star of India or the Red or Blue Ensign defaced with the Star of India.
While the Blue Ensign was used for military and naval purposes the Red Ensign was used for representing India in most international Events. The Star of India had a star with the words Heaven's light our guide around them, and was the badge of the Order of the Star of India, a chivalric order of knighthood.
