Shakuni was the King of Gandhar empire. This place is in today's Afghanistan. He was the sister of Hastinapur Maharaj and Dhrutarashtra, the father of Kuruvas and Kaura's maternal uncle. Shakuni is considered to be behind the dirty policies of Duryodhana and it is considered as the chief of the culprits for the battle of Kurukshetra. He tricked the Pandavas many times and incited his nephew Duryodhana to do untrue movements towards the Pandavas.
was born here to King Saujhad of Gandhar. Shakuni's sister Gandhari was married to Dhritarashtra. The reason for the dislike of Shakuniye's Kuruvishth was that Bhishma, the commander of Hastinapur, went to Gandhara once to demand Gandhari's hand for Dhritarashtra. Then Gandhari's father Sobhal accepted this, but at that time he did not know that Dhritarashtra is the birthdate. Its Shakuni also opposed, but Gandhari had so far considered Dhritarashtra as her husband. Therefore, on this day Shakuni took the vow that he would become the cause of the destruction of the entire dynasty. 
was divided into two equal pieces by dividing the state into two parts, that was completely barren, was given to the Pandavas, which he converted from his untiring efforts into a beautiful city called Indraprastha (present day Delhi). Soon there, the grandeur of that grandfather started to be far away. On the occasion of Rajshu Yagya by Yudhishthira, Duryodhana also had an opportunity to visit that grand city. He was observing the splendor of the palace, that at one place he considered the decoration of the water level as solid land and fell into it. Seeing this, Draupadi got laughing and said in a joke, "Blind son of blind". Duryodhana deemed his humiliation and returned to Hastinapur.
Predicting this mental state of his nephew, Shakuni got a bad idea of snatching the palate of the Pandavas in mind. He invited the Pandavas to play the game of Chaucer and using his crooked intellect to make Yudhishtir first to make small claims. When Yudhishthira made the mind of leaving the game, someone would have claimed something from Yudhishtir by saying something or something by Shakuni. Thus Maharaj Yudhishthira defeated each and every object by putting them on hold and finally put his brothers and his wife on the dowry and also defeated them and thus Duryodhana insulted Draupadi for his retribution And on that day the foundation of Mahabharata's war was laid.
the war of Kurukshetra, Shakuni was killed by Sahdev in the 18th day of war. All his brothers were killed by Ervan and Arjuna.
