50 years ago, on Thursday, June 23, Title IX of the Education Amendments of 1972 was signed into law. This act changed the trajectory of women’s athletics and will continue to shape its future.

The 37 words of Title IX prohibit discrimination on the basis of sex in federally funded educational programs and activities. It took years after the law was passed for it to begin to catch on, but it eventually led to the rise of collegiate women’s sports programs and professional leagues. But while there has been great progress, there is also a long way to go.

This month, leagues, athletes and leaders honored the law’s 50th anniversary. Here’s more on Title IX, women’s sports to watch on Thursday, and how the sports world is celebrating the anniversary this weekend.
