A day after the inauguration of the 45th President of the United States, the world turned pink. Thousands of men and women took to the streets worldwide to ensure that women's rights are not infringed. The main event took place in Washington D.C. on the national mall. What began with a simple facebook invite blossomed into massive demonstrations on all seven continents and in major cities around the world.

It began the night after the election. Outraged with the results, Hawaii citizen Teresa Shook felt that she had nowhere to share these feelings in her island community. She took to facebook and posted a simple idea: let's march. Four weeks later, more than 125,000 people had already signed up to march in the nation's capital with a main theme: Women's rights are humans rights, and human rights are women's rights. On the day of the march, around 200,000 people were expected. 500,000 people turned out in Washington. The demonstration had gone from a simple post to a movement, and one of the largest protests of a presidential election on record--outnumbering the crowd at the inauguration of President Trump by tens of thousands.

Sister marches were organized in all 50 states and around the world to show solidarity with the main march in Washington. Here are some images from the historic movement that spanned all cultures and united women and men around the world.

As these images show, the power behind these marches are staggering. While there are many different reasons for protesting, the main theme is the same: We are women. No matter what the next four years hold, we will not stand idly by. We will control our own destiny, and we will stand by our sisters in all parts of the world.
