To honor the 170th anniversary of the organization of the Relief Society, which takes place on March 17, 2012, members of the organization around the world are invited to participate in activities that engage them in the work of Relief Society. This anniversary is significant, said the Relief Society general presidency, because it follows the publication of Daughters in My Kingdom: The History and Work of Relief Society, and it presents a natural opportunity for sisters to reinforce in their lives the purposes taught in the book.
