(CNN) -- The struggle for women's rights against the backdrops of the Arab Spring and democratic progress in Africa will be recognized by this year's Nobel Peace Prize on Saturday, at a ceremony unlikely to repeat controversy seen last year. Liberian President Ellen Johnson Sirleaf, and Leymah Gbowee, a social worker and peace campaigner from the same country, will share the prize with Tawakkul Karman, an activist and journalist who this year played a key opposition role in Yemen. The three, chosen "for their non-violent struggle for the safety of women and for women's rights to full participation in peace-building work," will be honored in Oslo, Norway, during a program of events that culminates on Sunday in a star-studded concert.Three women to jointly receive the 2011 Nobel Peace PrizePrize recognizes non-violent struggle of safety of women and women's rightsPrize winners to be honored with a concert on Sunday hosted by Helen Mirren
