On July 2, 1776, two hundred and thirty-eight years ago today, the Continental Congress voted that “These United Colonies are, and of right ought to be, free and independent states.”

John Adams, who more than any other single individual, helped push the resolution through Congress, was elated. The next day he wrote home to Abigail twice.

“Yesterday the greatest Question was decided, which ever was debated in America, and a greater perhaps, never was or will be decided among Men. A Resolution was passed without one dissenting Colony “that these united Colonies, are, and of right ought to be free and independent States, and as such, they have, and of Right ought to have full Power to make War, conclude Peace, establish Commerce, and to do all the other Acts and Things, which other States may rightfully do.” You will see in a few days a Declaration setting forth the Causes, which have impell’d Us to this mighty Revolution, and the Reasons which will justify it, in the Sight of God and Man. A Plan of Confederation will be taken up in a few days.

When I look back to the Year 1761, and recollect the Argument concerning Writs of Assistance, in the Superiour Court, which I have hitherto considered as the Commencement of the Controversy, between Great Britain and America, and run through the whole Period from that Time to this, and recollect the series of political Events, the Chain of Causes and Effects, I am surprized at the Suddenness, as well as Greatness of this Revolution. Britain has been fill’d with Folly, and America with Wisdom, at least this is my judgment. — Time must determine. It is the Will of Heaven, that the two Countries should be sundered forever. It may be the Will of Heaven that America shall suffer Calamities still more wasting and Distresses yet more dreadfull. If this is to be the Case, it will have this good Effect, at least: it will inspire Us with many Virtues, which We have not, and correct many Errors, Follies, and Vices, which threaten to disturb, dishonour, and destroy Us.”

Liberty and independence were a challenge and an opportunity, Adams noted, “The People will have unbounded Power. And the People are extreamly addicted to Corruption and Venality, as well as the Great.”

In his second letter, Adams exhibited remarkable prescience, albeit he got one key detail wrong:

“The Second Day of July 1776, will be the most memorable Epocha, in the History of America.

I am apt to believe that it will be celebrated, by succeeding Generations, as the great anniversary Festival. It ought to be commemorated, as the Day of Deliverance by solemn Acts of Devotion to God Almighty. It ought to be solemnized with Pomp and Parade, with Shews, Games, Sports, Guns, Bells, Bonfires and Illuminations from one End of this Continent to the other from this Time forward forever more.

You will think me transported with Enthusiasm but I am not. — I am well aware of the Toil and Blood and Treasure, that it will cost Us to maintain this Declaration, and support and defend these States. — Yet through all the Gloom I can see the Rays of ravishing Light and Glory. I can see that the End is more than worth all the Means. And that Posterity will tryumph in that Days Transaction, even altho We should rue it, which I trust in God We shall not.”
