Germany's Lutheran Church has elected a woman to lead the nation's Protestants for the first time in its history.

Margot Kaessmann was overwhelmingly voted into the church's top position on Wednesday.

The 51-year-old bishop holds a doctorate in theology and has four grown children. She is one of only two bishops in Germany's Protestant church.

She was ordained in 1985 and has held many offices within the church. Kaessmann is viewed as being politically active and media savvy.
