Perhaps the world's most famous disaster at sea was the sinking of the massive luxury liner RMS Titanic on its maiden voyage on April 15, 1912. At least 1,496 perished in the icy waters of the Atlantic.
The legendary ship was thought "unsinkable." Two of Titanic's three massive propellers are seen here before the ship was launched on its trip from England to New York.
The vessel struck an iceberg seen here from the rescue ship Carpathia.
Adding to the tragedy was the inadequate number of lifeboats for all aboard. Here, Titanic survivors make their way to the rescue ship, Carpathia.
A picture of the Washington Post second edition printed after the Titanic sank. Immediately after the ship's crash, a lot of conflicting reports were circulated.
While the Titanic's sinking was perhaps the most famous maritime tragedy, the high seas have claimed many lives dating back thousands of years. Seen here is the Costa Concordia, which sank off the coast of Italy in January 2012. At least 30 died. Read more about some of the deadliest tragedies at sea...
