Wikipedia or britannica? 
 its a mistake of this user Rajput334 that he is talking about tertiary source rather than secondary. Please have a sense of interpretation of word Wikipedia. if you don't then you probably need to discuss it at talk page,here.. 

 Wikipedia is a free, online encyclopedia with entries that can be created, added, and edited by anyone. You belong to Rajput caste,so you may try to hide the well known facts. Please dnt. 

 Wikipedia is not your personal property. Please dont surpass other editors again and again. Thank you
