Buddhism was largely (or totally) eliminated from many of the nations that are now Muslim, such as Afghanistan, Pakistan, etc. It was also largely eliminated from India, though some scholars believe that this was mostly the work of Muslims, rather than Hindus.
India
Actually there is no nation where any religion has been eliminated. There will always be someone that follows any religion in any country. The question then becomes which nation has surpassed the open expression of personal religious beliefs. That group is much larger essentially including all nations on Earth.Religion General supports this static that"Even though you can't proclaim you are a (name of religion" you know in your heart it's true"

India
Buddhism began in what is now India, in the area of Bihar, Northern India.
Zen Buddhism originated in China. It was a blending of Buddhist practices that had been imported from India with daoism. It then spread to Korea and Japan.
