(CNN)Countries around the world will celebrate International Women's Day on Sunday, March 8. The day not only recognizes the achievements made by women, but also brings awareness to the obstacles that still stand in their way.
What exactly is International Women's Day?
If you want to get involved or need a brief history lesson on its significance, here's everything you need to know:
Although the day wasn't officially recognized until 1977 by the United Nations, the history of the celebration can be traced back to the early 20th century, thanks to labor movements across North America and Europe.
Members of the women's movement in Russia during World War I celebrated the first International Women's Day on March 8, 1913 to peacefully protest the war. A year later, women across Europe held rallies in solidarity on that same date.
Following World War II, countries from all continents began using March 8 as a marker for advocating women's equality.
More than a century later, numerous events and marches still take place on that day to celebrate the achievements of women and to take action.
The United Nations is focusing this year on gender equality and human rights for all women and girls. The theme of the commemoration is: "I am Generation Equality: Realizing Women's Rights."
