The United Nations declared 2000 as the International Year for the Culture of Peace. The purpose of this year was to promote a culture of peace, which is a set of values, attitudes, modes of behavior and ways of life that reject violence and prevent conflicts. The year was also a time to reflect on the progress that had been made in promoting peace and to identify new challenges and opportunities for the future.
The United Nations has also declared other years as International Years, such as the International Year of the Family (1994), the International Year of the World’s Indigenous People (1993), and the International Year of the Ocean (2008). These years are an opportunity to raise awareness of important issues and to promote action to address them.
