Buddha himself was never a buddhist. It's his followers who are Buddhists. He's an enlightened being meaning he doesn't belong to any group or people. He belongs to every one seeking spiritual awakening. He belongs to even those who's not seeking spiritual awakening. You see his statues/pictures cross-legged eye closed and you call 'bhagwaan Buddha'. But with different perception if we look at the same thing, he's asking you to do the same, have we ever tried that at all? Sit, close your eye and stay like that as long as you wish to. That's all his message. It's finding yourself, knowing yourself, finding peace and sending message to others the same way. Any westerner can be a Buddhist, any middle eastern can be a Buddhist, in face regardless of race or religion, we all can be a Buddhist, all these rituals that came with the religion are man-made and we sometimes, relate ourselves only to specific group and religion. Anyone, who truly follows his principles, knows that he is in fact a spiritual being who showed us our potential to find ourselves. We all have eyes, but we are blind inwardly. 

When Buddha was born, there was no Nepal, there was no India. Time and time again, I've been writing same things to questions like these but the way people think, it's so bland, temporal and lacking or they're just pretending. 

Why does it even matter where they're from, they were on the Earth(and yes there is moon, mars out there lol ). In 1000 years prolly there may not be many countries known today? Forget about it, stop satiating your stupid temporary quest for needless recognition.
