Mother's Day Proclamation
Following this very potent Proclamation made in 1870, the Mothers' Peace Day Observance was held on the second Sunday in June, 1872. Such observances began to take place each year thereafter and paved the way for Mothers' Day Holiday in US on the second Sunday of May.
Though Ms Howe could not herself get the day recognized as the official holiday, she is revered for her significant contributions towards the celebration of the day and for bestowing honor on mothers.
Julia Ward Howe is also famous as the writer of the Civil War song, 'The Battle Hymn of the Republic'.
