During the period 1961–1973, five international exhibitions were organized under the title New Tendencies. They continued the development of ideas raised by Exat 51 during the 1950s, and formed part of the broader European post-informel art movement in the 1960s and 70s. They were the initiative of art historians and critics Dimitrije Bašičević, Božo Bek, Boris Kelemen, Radoslav Putar, Matko Meštrović and the artists Ivan Picelj, Vjenceslav Richter, Julije Knifer, Aleksandar Srnec, later by a group of younger artists: Juraj Dobrović, Miroslav Šutej, Mladen Galić, Ljerka Šibenik, and Ante Kuduz.
