With the United States celebrating in 2026 the 250th anniversary of the signing of the Declaration of Independence, Americans are reflecting on how historical highs — and lows — shaped the country into the nation it is today. The occasion comes at a time when national parks and historic sites are “at risk” and “government officials are removing, often without explanation, exhibits that enable us to see through the eyes of people who lived in a world different from our own,” said Carol Quillen at Time. Instead of shying from uncomfortable parts of the country’s past, take steps to better understand what happened by visiting places connected to movements and events like the abolition of slavery, the fights for civil and women’s rights and the forced displacement of Indigenous tribes and Japanese Americans.

Roosevelt signed Executive Order 9066, authorizing the forced removal from the West Coast of those deemed a threat to national security. This resulted in the U.S. government incarcerating more than 110,000 Japanese Americans and Japanese immigrants in 10 camps, which operated until the end of World War II.

The most well-known camp, California’s Manzanar War Relocation Center, held more than 10,000 people, all of them “crowded into barracks, surrounded by barbed wire and guard towers with searchlights and patrolled by military police,” said The Guardian.Manzanar is now a national historic site, where visitors can watch the short film “Remembering Manzanar,” explore a museum filled with historic images and artifacts and step inside Block 14. There are two barracks buildings, a mess hall and a women’s latrine, providing insight into what it was like to live here during incarceration. Further out, a cemetery monument stands in honor of the 150 people who died at the camp during their imprisonment.Where to learn more: Manzanar isn’t the only War Relocation Center open to the public.

At the National Civil Rights Museum, all these efforts are given the attention and respect they deserve, with visitors able to learn more about “some of the most important wins for freedom and equality in the U.S.” while “connecting them to current happenings,” said Time Out.

Exhibitions guide visitors through “enslaved peoples’ fight for freedom, the Civil War and Reconstruction, Jim Crow and resistance efforts in the 1960s,” with visitors able to listen to interact with media, listen to oral histories and watch films.The museum is at the site of the former Lorraine Motel, where Dr. Martin Luther King Jr. was assassinated in 1968.

The removal came after the Indian Removal Act was passed and signed by President Andrew Jackson in 1830, as gold was discovered on Cherokee land and white settlers jockeyed for more acreage.

About 100,000 women, men, children and enslaved people made the brutal trek, with an estimated 15,000 dying of disease and starvation along the way or shortly after resettlement. The Trail of Tears National Historic Trail passes through Alabama, Arkansas, Georgia,
