"As it was earlier "Mother's Day" in the U.S. was mostly marked by women's peace groups.<1> A common early activity was the meeting of groups of mothers whose sons had fought or died on opposite sides of the American Civil War. There were several local celebrations in the 1870s and the 1880s, but none achieved resonance beyond the local level.<2>
"In New York City, Julia Ward Howe led a "Mother's Day" anti-war observance in 2nd June, 1872<1><4><2>, which was accompanied by a Mother's Day Proclamation. The observance continued in Boston for about 10 years under Howe's personal sponsorship, then it died out.<5>"

Here is her Proclamation, which is now in the public domain:
Mother's Day Proclamation
Arise, then, women of this day!
Arise, all women who have hearts,
Whether our baptism be of water or of tears!
Say firmly:
"We will not have great questions decided by irrelevant agencies,
Our husbands will not come to us, reeking with carnage, for caresses and applause.
Our sons shall not be taken from us to unlearn
All that we have been able to teach them of charity, mercy and patience.
We, the women of one country, will be too tender of those of another country
To allow our sons to be trained to injure theirs."
From the bosom of the devastated Earth a voice goes up with our own.
It says: "Disarm! Disarm! The sword of murder is not the balance of justice."
Blood does not wipe out dishonor, nor violence indicate possession.
As men have often forsaken the plough and the anvil at the summons of war,
Let women now leave all that may be left of home for a great and earnest day of counsel.
Let them meet first, as women, to bewail and commemorate the dead.
Let them solemnly take counsel with each other as to the means
Whereby the great human family can live in peace,
Each bearing after his own time the sacred impress, not of Caesar,
But of God.
In the name of womanhood and humanity, I earnestly ask
That a general congress of women without limit of nationality
May be appointed and held at someplace deemed most convenient
And at the earliest period consistent with its objects,
To promote the alliance of the different nationalities,
The amicable settlement of international questions,
The great and general interests of peace.
The Grandmothers Mission Statement
WE, THE INTERNATIONAL COUNCIL OF THIRTEEN INDIGENOUS GRANDMOTHERS, represent a global alliance of prayer, education and healing for our Mother Earth, all Her inhabitants, all the children, and for the next seven generations to come. We are deeply concerned with the unprecedented destruction of our Mother Earth and the destruction of indigenous ways of life. We believe the teachings of our ancestors will light our way through an uncertain future. We look to further our vision through the realization of projects that protect our diverse cultures: lands, medicines, language and ceremonial ways of prayer and through projects that educate and nurture our children.
