Forbes released its 10th annual list of "Most Powerful Women," topped by well-known heavy hitters.
Following behind well-known dignitaries like German Chancellor Angela Merkel - number one on the list - are dozens of women who you probably don't know.
Here are seven women of enormous power whose names probably don't ring a bell:

She now runs Alibaba's "Small and Micro Financial Services Group," which is the country's largest online financial service platform. Her group's offerings include online payment system Alipay.
