This document discusses April 23rd National Sovereignty and Children's Day, a national holiday in Turkey. It was established by Mustafa Kemal Atatürk on April 23, 1920 when the Grand National Assembly first convened, establishing an independent Turkish state. Atatürk dedicated the day to children to emphasize they are the future of the nation. Since then, the day celebrates both national sovereignty and children. Schools hold week-long ceremonies and children symbolically replace government officials on this day. The UN and many countries now recognize April 23rd as International Children's Day.
