Jahangir Khan is one of the greatest sportsmen Pakistan has ever produced. The King of Squash as he was known as during his career, He was nominated as "Sportsman of the Millennium" by the Government of Pakistan.

The Greatest Athlete is the only squash player who has dominated as number one in international and North American hardball squash at the same time. He was the first player to win World Open Championships without dropping a game.

Khan was coached initially by his father Roshan, the 1957 British Open champion, then by his brother Torsam. After his brother's sudden death he was coached by his cousin Rehmat, who guided Khan through most of his career. In 1979, the Pakistan selectors decided not to select Khan to play in the world championships in Australia but he entered the World Amateur Individual Championship, at the age of 15, and became the youngest-ever winner of that event.

In November 1979, Jahangir’s older brother Torsam died suddenly of a heart attack during a tournament match in Australia. Torsam’s death affected Jahangir greatly and led to him considering quitting the game before pursuing a career in the sport as a tribute to his brother.

Jahangir Khan said in his book "Winning Squash" that "I was told I would never become world champion. I was the youngest, smallest, feeblest and sickest of the family. Neither the doctor nor my father believed there was any chance for me to become a good squash player".

In recognition of ruling the game for five years, Guinness Book of World Record declared his winning streak to be the longest by any top-level athlete. Jahangir Khan’s achievements brought him the title of “The King of Squash” and pundits of Squash dubbed him “the greatest Squash Champion”. He is considered the greatest player in the history of the game‚Äč.

Time Magazine has named Jahangir as one of Asia's Heroes in the last 60 years. Jahangir Khan was conferred with an honorary Doctorate of Philosophy by London Metropolitan University for his contributions to the sport.
