Mother worship which kept a festival to Cybele, a great mother of gods, and Rhea, the wife of Cronus, was held on March 15 to March 18 around Asia Minor. They insist that this custom spread around the world. Mothering Sunday is the celebration of motherhood in the United Kingdom. It is also known as Mid-lent Sunday, Rose Sunday and Laetare Sunday. It originally comes from the Victorian practice of allowing servants to return home to visit their mothers on this day. In the United States, Julia Ward Howe (May 27, 1819 - October 17, 1910) was a prominent American abolitionist, social activist, and poet. Howe’s Battle Hymn of the Republic was first published in the Atlantic Monthly in 1862 and quickly became one of the most popular songs for the Union during the American Civil War. After the war she focused her activities on the causes of Pacifism and women’s suffrage. In 1870 she was the first to proclaim Mother’s Day, with her Mother’s Day Proclamation.
