History

More than 150,000 U.S., British and Canadian troops stormed the beaches of Normandy, France, on June 6, 1944 — 80 years ago this week. A small handful told NPR about their experience.

In 1923, an Indian American man named Bhagat Singh Thind told the U.S. Supreme Court that he was white, and therefore eligible to become a naturalized citizen. He based his claim on the fact that he was a member of India's highest caste and identified as an Aryan. His claims were supported by the so-called Indo-European language theory, a controversial idea at the time that says nearly half the world's population speak a language that originated in one place. Theories about who lived in that place inspired a racist ideology that contended that the original speakers of the language were a white supreme race that colonized Europe and Asia thousands of years ago. This was used by many to define whiteness and eventually led to one of the most horrific events in history. On this episode of Throughline, we unpack the myths around this powerful idea and explore the politics and promise of the mother tongue.

June 6, 1944 the Allied Forces stormed the beaches of Normandy and took the Nazis by surprise in the largest sea-to-land invasion in history. This would be remembered as D-Day and would ultimately lead to the end of World War II in Europe. However, this planned attack wouldn't have been possible without deep knowledge of ocean tides! We get into the whole story, including why tides sit at the intersection of astronomy and marine ecology — and why understanding tides are key to a greener future.
