In today’s political climate, conspiracy theories are commonplace. But they’re nothing new. In fact, back in the 1960s, there was one organization that built a movement around them.

The John Birch Society was started by a small group of wealthy businessmen including Robert Welch and Fred Koch. It expanded, with chapters of like-minded Americans meeting in private living rooms and finished basements across the country, fueled by conspiracy theories that caused a schism in presidential politics.

While the Birch Society’s influence has waned, its impact is still felt today.

During the Dust Bowl of the 1930s, millions of desperate Americans abandoned their homes, farms and businesses. It was one of the largest migrations in US history. In the 1940s, Pat Rush’s family were farm laborers, exhausted by trying to make ends meet. So they left Arkansas and followed the hundreds of thousands who had traveled Route 66 to California. There, the federal government had built resettlement camps to help deal with the influx. Migrant stories have two parts: the leaving of an old life, and the building of a new one.

In the spring of 1981, the Pawtucket Red Sox and the Rochester Red Wings met for a minor league baseball game of little importance. But over the course of 33 innings — 8 hours and 25 minutes — the game made history. It was the longest professional baseball game ever played.
