MR. JUSTICE BLACK delivered the opinion of the

Court:

. . . We think that by using its public school system to encourage recitation of the Regents’ prayer, the State of New York has adopted a practice wholly inconsistent with the Establishment Clause. There can, of course, be no doubt that New York’s program of daily classroom invocation of God’s blessings as prescribed in the Regents’ prayer is a religious activity. It is a solemn avowal of divine faith and supplication for the blessings of the Almighty. The nature of such a prayer has always been religious, none of the respondents has denied this and the trial court expressly so found: . . .

The petitioners contend among other things that the state laws requiring or permitting use of the Regents’ prayer must be struck down as a violation of the Establishment Clause because that prayer was composed by governmental officials as a part of governmental program to further religious beliefs. For this reason, petitioners argue, the State’s use of the Regents’ prayer in its public school system breaches the constitutional wall of separation between Church and State. We agree with that contention since we think that the constitutional prohibition against laws respecting an establishment of religion must at least mean that in this country it is no part of the business of government to compose official prayers for any group of the American people to recite as a part of a religious program carried on by government.

It is a matter of history that this very practice of establishing governmentally composed prayers for religious services was one of the reasons which caused many of our early colonists to leave England and seek religious freedom in America. The Book of Common Prayer, which was created under governmental direction and which was approved by Acts of Parliament in 1548 and 1549, set out in minute detail the accepted form and content of prayer and other religious ceremonies to be used in the established, tax-supported Church of England. The controversies over the Book and what should be its content repeatedly threatened to disrupt the peace of that country as the accepted forms of prayer in the established church changed with the views of the particular ruler that happened to be in control at the time. Powerful groups representing some of the varying religious views of the people struggled among themselves to impress their particular views upon the Government and obtain amendments of the Book more suitable to their respective notions of how religious services should be conducted in order that the official religious establishment would advance their particular religious beliefs. Other groups, lacking the necessary political power to influence the Government on the matter, decided to leave England and its established church and seek freedom in America from England’s governmentally ordained and supported religion.

It is an unfortunate fact of history that when some of the very groups which had most strenuously opposed the established Church of England found themselves sufficiently in control of colonial governments in this country to write their own prayers into law, they passed laws making their own religion the official religion of their respective colonies. Indeed, as late as the time of the Revolutionary War, there were established churches in at least eight of the thirteen former colonies and established religions in at least four of the other five. But the successful Revolution against English political domination was shortly followed by intense opposition to the practice of establishing religion by law. . . .
