Final answer:
Geraldine Ferraro became the first woman nominated as a major-party vice presidential candidate in 1984.
Step-by-step explanation:
The first woman to be nominated as a major-party vice presidential candidate in 1984 was Geraldine Ferraro. In a significant moment for women's political representation, the Democratic party selected Ferraro to run alongside presidential nominee Walter Mondale.

Her nomination highlighted the growing influence of women in politics, particularly since the establishment of organizations like the National Organization for Women and the National Women's Political Caucus.
