Mabel Dawson (born 1892)

In 1892, in the year that Mabel Dawson was born, on October 12th, the "Pledge of Allegiance" was first recited in unison by students in U.S. public schools. Composed the previous August by Francis Bellamy, it was to be recited in 15 seconds and originally read: "I pledge allegiance to my Flag and the Republic for which it stands, one nation, indivisible, with liberty and justice for all."

In 1904, the Russo-Japanese war began. The Russian Empire and the Japanese Empire began fighting over the territories of Manchuria and Korea.

So the Japan fleet launched a surprise attack on the Russian Navy and a one year war began. President Roosevelt of the United States brokered peace between the two nations. It was the first time in the modern era that an Asian power showed its dominance over a European power.
