For Dr. Marc Sanko, history has always been personal.

Before he studied it professionally, taught it to students or built a career around understanding change over time, he heard it in family stories. He grew up in a Mediterranean family outside Detroit, listening to relatives talk about Malta, migration and a city that had changed dramatically within a single lifetime.

His grandparents came to the United States in the 1930s and spent their childhoods in Detroit. They remembered a city full of energy, shopping, tourism and opportunity. But as a child in the 1990s, Sanko saw a different Detroit.

鈥淚t made me wonder, what happened?鈥� Sanko said. 鈥淗ow did we get to this point? Where did things change?鈥�

Those questions became the foundation of his future.

Sanko, now an associate professor of history at 海角视频, brings that same curiosity into his teaching. For him, history is not simply a record of what happened. It is a way of understanding how people, places and nations become what they are.

As the United States marks 250 years, Sanko sees the American experience as something deeply aspirational. It is not a finished achievement, but a continuing effort to move toward the ideals the nation has long claimed for itself.

鈥淭he United States is aspirational,鈥� Sanko said. 鈥淎nd when you have that big, big target up top that says we're going to strive to be equal and great and wonderful, I mean, that's almost an impossible thing to do.鈥�

But the striving matters.

鈥淏ut if you're striving towards it, then that means everything's a challenge,鈥� he said. 鈥淎nd sometimes and that's not a bad thing. Challenges can be good because you can grow from challenges.鈥�

That is one of the lessons Sanko emphasizes when teaching American history. The country鈥檚 story, he said, includes flaws, contradictions and unfinished work. But it also includes an ideal that has continued to pull people forward.

鈥淭here were a lot of flaws in everybody,鈥� he said. 鈥淭here's a lot of flaws in every single human being. There's a lot of flaws in the founding fathers.鈥�

Still, Sanko said, the founding ideal of equality has remained a kind of guidepost.

鈥淏ut the one thing that they did right, that I think has given us a North Star to head towards constantly, no matter what's happening in this country, is that that opening preamble that we are all, equal, and that that this is a nation founded upon the ideal of equality,鈥� he said. 鈥淣ow, we've never ever gotten there. But we've always tried to go there.鈥�

For Sanko, that effort helps explain many of the defining movements and conflicts in American history, including the Civil Rights Movement and broader struggles over who is included in the nation鈥檚 promise.

鈥淲e're always headed that direction,鈥� he said. 鈥淎nd a lot of the biggest fights that we end up having in this country amongst ourselves are, like, how do we get to that point? How do we become what the founders wanted us to be?鈥�

Immigration is part of that evolving story. Sanko points out that while the United States is often described as a nation of immigrants, its history includes repeated moments of resistance to new groups of people.

鈥淭here's also really hardly ever been a time where despite being a nation of immigrants, we've been very accepting of immigrants,鈥� he said.

Across generations, he said, different groups have been treated as outsiders before becoming part of a broader American identity.

鈥淭here will always be problems,鈥� Sanko said. 鈥淭here will always be issues. My hope would be that people retain these aspirational things that we've been talking about.鈥�

For Sanko, the American experience is not only about what the country has been. It is about the ideas people continue to carry forward, test, challenge and try to make real.

鈥淚 think they're good ideas,鈥� he said. 鈥淭hey're ideas that organize society in a way that should be, in theory, equal.鈥�
