Gary Gallagher, a historian, discusses lessons from the Civil War for modern times. He emphasizes the republic's resilience, having weathered tougher times, and expresses faith in the U.S. to overcome current challenges. He notes that the founding documents allowed adaptation, leading to the 13th, 14th, and 15th amendments despite racial prejudice. Gallagher highlights that wars unleash unpredictable changes, citing federal budget growth from $63 million in 1860 to $1.2 billion in 1865, and the creation of land grant colleges. He argues that US history's arc is an expansion of freedoms, though complex and messy. He criticizes the desire for simple 30-second views of history, stressing that the past is complicated, and learning reveals more ignorance. He humorously compares humility in leaders, favoring Grant over McClellan.
Key takeaways
The Civil War led to 13th, 14th, and 15th amendments, expanding freedoms.
Federal budget grew from $63 million in 1860 to $1.2 billion in 1865.
History is complex; there is no 30-second version of the past.
But you know, we're living today, 2026. And there's a sense that every day you wake up, the possibilities before us are endless. For the good, for the bad, for the truly destructive. There's an eerie sense that the possibility of a world war in different kinds of ways, whether it's sparked in the Middle East or sparked in China and Taiwan, or sparked in Ukraine-Russia, or elsewhere totally surprising in the world, maybe related to nuclear weapons or not. There's a sense that everything is possible. And of course, when history is written about the 21st century, it will all be obvious.
Well, I think that the potential threats now are different from the potential threats in the mid-19th century. The nuclear dimension, some kind of really brutal use of pathogens. That means that there are lots of things that could happen now that couldn't happen then, at least not because humans were making them happen. But I mean, to me, one of the things to take away from the Civil War is really the resiliency of this republic. Which I still think it's a resilient republic. We're living in a sort of wacky time. But I believe that, I think that I have a great faith in the resiliency of the nation, I really do, of the United States. I think it's been through much tougher times than we're in now. And I think that we will weather this, although everybody will have some scar tissue.
There might even come a time when our leadership class actually leads, which would be interesting. And I'm talking about both sides of the fence here. But to me, this is the supreme test of a republic that had been put in place in the late 18th century. Can that late 18th century republic adjust, including adjusting to deal with the profoundly disruptive issue of slavery in a way that allows it to go forward? And the answer is yes. In a war that brings slaughter on an unimaginable scale and brings social disruption in the former slave-holding states on an unimaginable—just couldn't be more profoundly disruptive if you're a Confederate. There's not slavery anymore, and we lost the war, and a third of our military-age white men are dead. Wow, that's a bad four years for our team. What's going to happen here? The republic emerged from that and worked it out, and I think it goes back to me to the intelligence of the founding generation that put in place documents that actually allowed the republic to deal with something like this. And it's sort of a miracle to me that from a nation that was as racially prejudiced as the United States was, you get the 13th, 14th, and 15th amendments out of this. It's just kind of mind-boggling that that happens.
It absolutely does. It absolutely does. But then when you really get to the end of that story, you look and there you are. And oh, it's okay, the nation is still intact. And the 13th Amendment is in place. Wow, we didn't think that was going to happen in 1861 when secession started. I mean, it really—one another lesson is that you cannot control what a great military event can set loose. I mean, no things that nobody imagined would happen, including expansion of central power in ways that no one would have imagined. You don't get to ratchet that back and say, 'Well, that'll never happen again.' No, you know what? It happened and maybe it will happen again because we've seen it happen. Nobody imagined that the federal budget in 1860 was $63 million. That was the entire federal budget. The federal budget in 1865 was $1.2 billion, and if you throw in the Confederate side of that, it gets you over $2 billion, which means federal expenditures in 1860 would have lasted about 11 days in 1865. Nobody foresaw that. No, absolutely nobody foresaw that. And education legislation that would create the great land grant colleges and universities. And no, it's the war—the war brought a lot.
And I think most of the things that have happened through the hard periods of our country's history nobody could have really foreseen, and then we somehow figure it out. And that gives me a lot of hope that this kind of extreme division, the arguments that people basically speaking in the harshest of ways against each other, that is like the engine of brainstorming and figuring problems out that in the long arc of history create progress. But in the short term it feels like a dumpster fire.
It does. And to me, the arc of US history has been—and Lincoln talked about this too—it's an expansion of freedoms and liberties. That's the long arc. With very problematical places along the way. But again, the documents allow for that and the process allows for that. And I think that's one of the remarkable things about Philadelphia in the summer of 1787. I mean, all those guys, a lot of whom owned slaves, put together something that's proved to be resilient and adaptable and changeable, and it has evolved in a way that is in the right direction. Although there are always problems.
