According to Proverbs 13:20, "You are the company you keep," but if you looked at the friendship of Thomas Jefferson and John Adams, you could not find men so different. Jefferson was a political radical and envisioned himself as a champion of democracy, he was an aristocrat and a planter, he was a Southerner and a slaveowner. Adams, on the other hand, came from New England's rising middling classes, and while he was a revolutionary, he was a much more conservative thinker, and at his core was a political skeptic and a pessimist about human nature.But in the crucible of revolution, an unlikely friendship was born and continued to blossom while the pair were in France together. But ultimately, their profound differences would lead to a fundamental crisis, in their friendship and in the nation writ large, as they became the figureheads of two entirely new forces, the first American political parties. It was a bitter breach, lasting through the presidential administrations of both men, and beyond.But as the early 19th century came into focus and the Age of Jackson began to dawn, these two men were nudged into reconciliation.To explain this fascinating tale of friendship, division, and resolution is Gordon S.
