Women throughout the world joined hands in support of one another for International Women's Day yesterday.
Celebrated since the early 1900s, IWD was founded with the idea of celebrating "the social, economic, and political achievements of women," according to the organization's website.
Interestingly enough, the organization cites a 15,000 women's worker march in 1908 down the New York City streets as the first step toward Women's Day becoming an international holiday – although it wasn't officially recognized by the United Nations until the '70s.
Yesterday, with at least double that attendance, demonstrations took place in parks, colleges, high schools, middle schools and the work place, across the globe.
They wore red in solidarity, took to the streets by the thousands and made their voices heard to protest the same thing as always – equality.
Also, in addition to International Women's Day, the group who organized the Women's March on Washington D.C. went on a strike yesterday called "A Day Without A Woman."
The purpose of the strike was to stand up for "equity, justice, and the human rights of women and all gender-oppressed people."
