Turkey's most influential businesswoman, Sabanci, 58, lands at No. 2 on our list this year (up from No. 6 last year and No. 20 a decade ago.) German electronics giant Siemens elected her to its supervisory board;a powerful advocate for Turkey's EU bid, she is also leading the charge for the country's vision to be among the top ten global economies by 2023. Within Turkey her reach is undeniable: She employees a workforce of some 60,000, and her businesses—spanning from cement to banking to energy—generated revenues of $14.6 billion in 2012; profits topped $1 billion fuelled by new projects in the energy sector. The group's $10 billion in market capitalization has almost doubled in the last two years.
