Who established Hindu dharma and when?

There is no define set date record, as to its establishment, but it is definitely a very ancient Dharma. In fact to say that, it is the world's oldest religion, would not be wrong. Our ancestors were Aryans and this word in Sanskrit means 'great' since they practiced Santan Dharma. Today we call it hindu dharma. It was not started by anyone, but by God himself, who gave 'Rigved and other Vedas.

Which is their main scripture?

Hindu dharma has the 'Ved' as its main scripture (religious book). The word Ved is derived from the word 'Vid'. Vid = to know. Ved = knowledge. Which consists the total knowledge of dharma is ved. Ved was not man's work, but they are a creation, manifestaion from God's breath and hence they are considered to be God' words. His words are expressed in this form. It is the world's oldest scripture. However, it was simplified and modified by a great rishi, a saga called Vyasji. Being a wise learned scholar, he categorized it, subjectwise, thus splitting it into 2 section, Uttarkand and Poorvakand. The latter contains information on how to perform yagna to obtain Lord. The former contains, detailed description about God, The Universe, the Soul etc.

Since there was a different type of system in ancient times, of no books being written, the guru disciple tradition was one, where the guru spoke, and the disciple heard it and memorized it. But it was not easy to remember the entire recitation. To facilitate this situation, Ved Vyasji made four parts of the Ved. They are

1. Rigved
2. Yajurva Ved
3. Sam Ved
4. Atharva Ved
