What significant event related to the "Pledge of Allegiance" happened in 1892?

In 1892, the "Pledge of Allegiance" was first published as part of a campaign by the National Education Association to promote patriotism in schools. Francis Bellamy, a socialist and a member of the Baptist church, authored the original version, which was intended as a pledge for children to recite as part of their daily measures in the educational setting. This publication marked a significant moment in American history, as it laid the groundwork for the Pledge's inclusion in school routines and national identity.

While the other choices relate to various stages of the Pledge's history, they do not pertain to the original event of its publication in 1892. The Pledge's adoption by Congress occurred later, in 1942, solidifying its place in American culture and government. The broadcast on radio happened after the Pledge gained popularity, and although Bellamy wrote the Pledge, the significance of 1892 rests specifically on its publication and its initial role in promoting American nationalism among schoolchildren.
