Re: Teree Vijaay haain!!!
Rather than go to google and cut/paste, I thought it may be better to write down one's understanding of the epic. Here is a start, based on what I can recall.
The head of the Kuru Vansh (dynasty) was Santanu. He had one son, who later on became known as Bhishma. Santanu fell in love with Ganga, who agreed to marry him if her son was made the king upon Santanu's death. Subsequent events led to Bhishma taking a vow never to marry, so that his younger brother's kids could inherit the throne. While trying to get a bride for his younger brother, he wins the hand of 3 sisters Amba, Ambika and Ambalika. But one of the sisters (Amba?) is rejected by all, and turns to Bhishma. However, Bhishma having taken a vow never to marry, had to reject her. Out of anger, Amba does penance, and is granted her wish to be reborn as a man, known as Sikhandin, to kill Bhishma. In the meantime, one of the sisters gave birth to Dhritarashtra and Pandu, while the other sister's maid gave birth to Vidura, who thus was a cousin to Dhritarashtra and Pandu. Dhritarashtra, the elder brother was born blind, hence Pandu performed the daily duties of ruling the kingdom. (I may have missed a generation here - but am recollecting from 30 years ago, so help me God).
Dhritarashtra's wife, the noble Gandhari, tied a cloth around her eyes so that she also could see only what her beloved husband could see. Gabndhari gave birth too 100 sons, known as Kauravas, the eldest of whom was Duryodhana. There was also another son (possibly through a maid), whose name was Yuyutsu. So technically, there were 101 sons of Dhritarashtra.
Pandu married Kunti and Madri, the latter being younger. One day, Pandu and Madri were relaxing in the forest (Ban or Van). They saw a beautiful male and female deer engaging in the act of love. Pandu shot the male deer (or both). Upon being struck, the deer took their original form (of devas/gods) and cursed him - "you shall never enjoy marital bliss. If you do, you will die".
Years ago, Kunti had been given a boon by sage Durvasa that she will have children through various gods - Yama (Death) Vayu (wind), Indra (rain?), and two other gods. (There was one more son, but patience please!)
Now that Pandu had been cursed, Kunti invoked her powers to be blessed with Yudhishtira (Dharmaputra, son of Yama), Bhima (wind), Arjun (Indra). She also helped Madri conceive twins Nakula and Sahadeva. Nakula was great with horses, while Sahadeva was a superb swordsman (like our Faris!) Yudhisthira was known as Dharmaputra, because he never swerved from the path of righteousness/Dharma. His weapon of choice was a javelin. Bhima was extremely strong, and his weapon was a mace (gadha). Arjuna was an excellent archer, in the same class as Rama and Krishna.These 5 were the Pancha Pandavas.
Now you have been introduced to the Kauravas and Pandavas, who went on to fight the battle of Kurukshetra.
