ILTF Women's Grand Prix
The 1971 ILTF Pepsi-Cola Women's Grand Prix was a tennis circuit administered by the International Lawn Tennis Federation. The circuit consisted of the four modern Grand Slam tournaments and open tournaments recognised by the ILTF. This article covers all tournaments that were part of that year's Women's Grand Prix.Virginia Slims Circuit
Prior to the establishment of this circuit there was an inequality between the prize money purses for male and female tennis players which gave rise to complaints from a number of the leading female tennis players of the time. Nine of them, including Billie Jean King, became later known as the "Original 9" after being banned from the then existing multi-gender invitational professional events run by the influential United States Lawn Tennis Association due to their boycotting of the Pacific Southwest Championships. This resulted in the first Virginia Slims-sponsored event being held in September 1970 in Houston, an event which laid the groundwork for the establishment of the annual Virginia Slims Circuit the following year. In 1971 the total prize money available from the Virginia Slims events was $309,100 and Billie Jean King became the first female athlete in history to earn more than $100,000 in one season.ILTF sanctioned tournaments
