Merkel, considered one of the world's most powerful women, said today in a video message that "many women before us have made sacrifices and fought persistently so that women would have more rights ... but there's still a lot to do."
The chancellor said that, "there are also new tasks for men", but she didn't elaborate further.
Merkel added, "Therefore today is not only a day to look back at what has been achieved, but also a day on which we say the struggle for equal rights of women continues.
