Her role mostly involved what diplomats call "soft power" -- converting cold war foes into friends, supporting nonprofit work and good-will endeavors, and pressing her agenda on women's rights, human trafficking and the expanded use of microcredits, tiny loans to help individuals in poor countries start small businesses.
...The foreign policy achievement most often credited to Mrs. Clinton came in 1995, with her speech to the United Nations conference on women in Beijing, where she declared that "human rights are women's rights, and women's rights are human rights." She also tangled with Chinese officials, she said, and refused to bow to pressure to soften her remarks.
"She had a good balance of being firm on these issues, even if they clearly covered Chinese sins, but also understanding the need for good relations with China," said Winston Lord, then the assistant secretary of state for East Asian and Pacific affairs, who briefed and accompanied her on the trip.

d) Health Care Task Force (See fantastic discussion by digby here)

e) Children's Defense Fund legislation showing the influence of Hillary's interests(link, link):

The Clinton administration enabled the most powerful successes of CDF to date. A deep commitment to children's issues was shared by Hillary Rodham Clinton, a college friend of Edelman's. This political backing yielded improvements such as an increase in the Earned Income Tax Credit, which provided more support to working parents. Other legislation enacted during this time period included the Childhood Hunger Prevention Act and the Family and Medical Leave Act. Funding was also increased for the Head Start program and for child immunization.

The president promoted several of the CDF's positions in his legislative goals: he signed family leave legislation into law and stepped up enforcement of child support payments with the help of the Internal Revenue Service. He also proposed budgets that would fully fund or expand Head Start and WIC, advocated a comprehensive federal immunization program for children, and supported health care reform that would ensure care for children and pregnant women. Although not all these initiatives succeeded in Congress, the effort reflected the growing influence of the CDF on national policy.
