no steena every person who is Hindu can celebrate it but it is most widely and enthusiastically celebrated I Maharashtra because Lokmanya Tilak one of the most prominent freedom fighter of India started celebrating this festival publicaly so that people could come together and unity would increase in India so it would help in fight for freedom before this people celebrated ganesh chaturthi at their homes only he first started this in Pune and Mumbai so these two cities from thattime celebrate ganesh chaturthi with much enthusiasm 😃 hope you don't get bored of this history lecture 😆 😛
