Children, also known as "June 1 International Children's Day," the annual June 1, the world of children's festivals. November 1949, the Women's International Democratic Federation council meeting held in Moscow. China and other countries and representatives of countries and anger exposed the imperialist reactionaries kill and poison children. In order to protect the world's children to survival, health and education, to improve the lives of children. The meeting decided in the annual June 1 International Children's Day.
The International Children's Day (ICD) is celebrated in numerous countries, usually (but not always) on June 1 each year.
The ICD had its origin in the World Conference for the Wellbeing of Children in Geneva, Switzerland in 1925. It is not clear as to why June 1 was chosen as the ICD: one theory has it that the Chinese consul-general in San Francisco (USA) gathered a number of Chinese orphans to celebrate the Dragon Boat Festival in 1925, which happened to be on June 1 that year, and also coincided with the conference in Geneva.
June 1 has since been observed as the ICD by numerous countries, especially by Communist countries; in the Western world the ICD is usually celebrated on other days of the year (if at all), and there is often little public awareness about these celebrations. (See the section on Germany below for further discussions.) Consequently there is sometimes a misperception that June 1 as the ICD was a Communist invention. Nonetheless, in recent years even some groups within the United States started observing the ICD on June 1.
1942年6月，德国法西斯党卫军包围了现在捷克共和国的首都布拉格市附近的利迪策村，枪杀了16岁以上男性公民140多人，全部婴儿和妇女被押往集中营，另外有90名儿童被押往波兰的一个集中营（其中只有17人活到战争结束）。村里所有的房舍、建筑物均被烧毁或被铲土机夷为平地。就这样，一个好好的村庄被法西斯党卫军毁灭了。
为了悼念利迪策村和全世界所有在战争中死难的儿童，反对帝国主义战争贩子虐杀、毒害儿童，保障儿童的权利，1949年11月在苏联首都莫斯科召开的国际民主妇女联合会理事会通过一项决议，正式决定每年的6月1日为全世界儿童的节日，即“六一”国际儿童节。
国际民主妇联作出每年6月1日为国际儿童节的决议后，1949年12月23日，我国中央人民政府政务院第十二次会议通过了统一全国年节和纪念日放假的办法，其中决定自1950年起，每年以6月1日国际儿童节作为中国儿童自己的节日，并放假举行庆祝。从此中止了1931年起由中华慈幼协会建议的每年4月4日为我国儿童节的活动。
于是，1950年6月1日便成了我国建国后的第一个“六一”国际儿童节。
此后，我国每年的6月1日都举行各种活动，庆祝“六一”国际儿童节。
