     Jeanette Rankin was born on a ranch in Montana, USA in 1882. In those days, Montana was still a

frontier state, and life there was hard. Men and women shared the difficult outdoor work. But young

Jeanette noticed men and women were not equal in many ways. For instance, at election time, women

were not allowed to vote. Jeanette thought this was not fair, and several years later, after graduating from

college, she realized how to help change the situation.

     First, she joined with other women. and gave speeches through the state. Thanks to their years of

efforts, Montana women were finally allowed to vote. This experience changed Jeanette's life. She

wanted do work for the welfare of women and children everywhere. She was now well-known

throughout Montana, so she decided to run for the US Congress. In 1916,she became the first woman

in the Congress of the United Staters.

     Just six days after Rankin first attended Congress in 1917,American President Wilson called for a

vote to go to war against Germany, as German submarines (潜水艇) attacked American ships during

World War I. When Jeanette was called upon to vote, she said, "I want to stand by my country, buy I

cannot vote for war. I vote no." Forty-nine other congress members also voted no, but she was the

person who was criticized most. Newspapers said her decision came from weakness and she was

anti-American.

     In the Second World War, Japanese warplanes attacked the American base at Pearl Harbor in

1941.The time came again for the US Congress members to vote for or against going to war. Everyone

was waiting for Jeanette Rankin to vote, who rose and said, "As a woman, I can't go to war, so I refuse

to send anyone else". Out of 471 members, she was the only member who voted against war. After

that, she received thousands of letters. Most people criticized her, but some praised her for her courage.

     Shortly before she died in 1973, she was asked if she regretted voting "no" to the two wars. "Never,"

she answered. "If you are against war, you're against war regard less of what happens."

     Today, in the US Congress Building, there is a statue of Jeanette Rankin. On the base of the statue
