Article 18 of the Indian Constitution deals with the abolition of titles. Here is a summary of the article based on the search results:

• No title, not being a military or academic distinction, shall be conferred by the State.
• No citizen of India shall accept any title from any foreign State.
• No person who is not a citizen of India shall, while he holds any office of profit or trust under the State, accept without the consent of the President any title from any foreign State.
• No person holding any office of profit or trust under the State shall, without the consent of the President, accept any present, emolument, or office of any kind from or under any foreign State.

It is important to note that the recent conferment of titles such as "Bharat Ratna", "Padma Vibhushan", and "Padma Shri" are not prohibited under Article 18 as they merely denote State recognition of good work by citizens in various fields of activity.
