Which voting-rights cause did the 1910 Women's Day strategy help promote?

The 1910 Women's Day strategy helped promote women's suffrage. Winning the vote was a central demand of the international socialist women's movement and a major part of the equality agenda behind the proposal.

At the Copenhagen conference, delegates endorsed an annual Women's Day after Clara Zetkin presented the idea. The observance was intended to mobilize women and public opinion around equal rights, including the demand for women to participate fully in political life through voting.

Women's Day was therefore not originally just a ceremonial holiday. Early demonstrations connected workplace concerns, peace, social legislation, and political equality. Universal suffrage meant voting rights for women, although the timing and scope of those rights differed widely from country to country. Secret ballots and direct democracy were voting-system concepts, not the specific cause identified in the conference's stated aims.
