Over thousands of years, Polynesians migrated across vast distances and spread their culture across the Pacific.
Sailing without a chronometer, the Arniston crashed into reefs along the coast of South Africa and sank on May 30, 1815, killing about 340 people. Heading for the Horn of Africa, the ship’s captain headed north before he should have and slammed into the Lagullos Reef. The crew tried to save the ship, but it broke up in the sea, killing all the passengers and all but six of the crew.
