At present universal peace is a matter of great importance, but unity of conscience is essential, so that the foundation of this matter may become secure, its establishment firm and its edifice strong. 

Therefore Bahá'u'lláh, fifty years ago, expounded this question of universal peace at a time when He was confined in the fortress of 'Akká and was wronged and imprisoned....

Among His teachings was the declaration of universal peace....the teachings of Bahá'u'lláh were not limited to the establishment of universal peace. They embraced many teachings which supplemented and supported that of universal peace. (‘Abdu’l-Baha, ‘Selections from the Writings of 'Abdu'l-Bahá’; The Compilation of Compilations, vol. II, Peace)
