Lansbury became a teacher, and joined the
East London Federation of Suffragettes in 1915. She made arrangements with the film distribution company
Pathé News to film
suffrage meetings. Lansbury was persuaded by
Sylvia Pankhurst to give up her teaching post to become the secretary of the League of Rights for Soldiers' and Sailors' Wives and Relatives, fighting for the rights of
widows,
orphans and wounded soldiers from
World War I. She was the first woman to be elected
alderman on Poplar’s first Labour council in 1919, after a change in the law allowed some women to receive Parliamentary
suffrage and stand as candidates. She said of the arrests that "if we said the word, the people of Poplar would prevent our arrest by no less than a machine-gun corps." Lansbury was buried in the Jewish cemetery in
East Ham, with "thousands" of women assembling near her home to walk with the funeral procession. == Legacy ==
