Indian and Hindu are two different terms. Indian refers to a citizen of India. India is one of the most populous countries in the world. And the word 'India' can be used for a lot of things. It can be used to describe someone that lives in India. You might not be a citizen of India by birth, by you can be called an Indian by virtue of marriage, or by honorary citizenship. Indian can also be used for a lot of things that belong to India. Hindu, on the other hand, refers to someone adhering to Hinduism.
This means Hindu is any person who believes in Hinduism and follows the various doctrines and practices of Hinduism. According to this definition, it shows that a person can be adhering to Hinduism without necessarily a native of India. Hindu can be anybody as long as the person is faithful to the teachings and practices of Hinduism
India is a country that has a rich history because it dates back to ancient history compared to other countries. The people who live there are known as Indians. Some people get that confused because the Native Americans who lived in the United States centuries ago became known due to an error by Christopher Columbus.
He thought he had traveled to India, but instead, he landed in a new world that would later become known as the United States. The Indians in India may be Hindu, but they don’t have to be. It depends upon the religion that they practice. Many people in India practice Hinduism, but not all of them. The main difference is that Indians are those who live in India and Hindu are those who practice Hinduism.
