5 wild conspiracy theories surrounding the sinking of the Titanic

Did an ancient mummy seal the Titanic's fate?

No. Human error and a lifeboat shortage brought about the maritime catastrophe.

Still, the idea that an ancient curse sunk the ship is one of the more fanciful conspiracy theories that cropped up in the wake of the disaster.

According to the legend, an ancient, mummified princess left a trail of death and devastation across England in the early 1900s after being excavated and removed from Egypt.

Once the beleaguered community of British art collectors and museum professionals had enough of the haunted mummy, an American archaeologist swooped in to purchase it. Ignoring his colleagues' warnings, he headed back to New York with his new acquisition.

But the unfortunate scholar and the mummy never made to the States. Because, lo and behold, the name of the ship that they sailed off on was the HMS Titanic!

The tale is popular, but also completely fictional. Snopes debunked the story, noting that, even disregarding the tale's fantastical elements, there was no mummy onboard the ship.

That hasn't stopped the British Museum's so-called "unlucky mummy" from getting blamed for the ship's sinking, though.

The Titanic is known as one of the biggest peacetime maritime disasters in history. The tragedy missed the onset of the First World War by two years.

But some still speculate that a German U-boat was really behind the ship's sinking.

If such a theory panned out, that'd make the Titanic's sinking a precursor to that of the Lusitania. In 1915, a German U-boat torpedoed the British ocean liner off the coast of Ireland, killing 1,198 people.

While the theory lacks an abundance of evidence, it's certainly not outside the realm of possibility.

A number of Titanic survivors reported to have noticed "an unidentified vessel approximately five to six miles away" from the sinking ship, which reportedly lingered until 2 a.m., according to Dr. Franklin Ruehl's piece in The Huffington Post. Ruehl speculated that the craft was possibly "a submarine that had surfaced to assess the damage it had caused, after which time it skulked off," and also cited survivor testimony about a number of explosions that seemed to go off deep with the ship.

"The sub may have deliberately targeted the luxury liner or possibly accidentally collided with it," Ruehl wrote.

What if the Titanic never sank at all?

That's the thinking behind one particular conspiracy theory. According to this idea, the Olympic — the Titanic's older, nearly identical sister ship — was actually the one that went down near Newfoundland.

But what would've been the point of switching the ships in secret?

In the book "Titanic: The Ship That Never Sank?" researcher Robin Gardiner wrote that the whole disaster was the result of an insurance scam by the International Mercantile Marine Co., which owned the White Star Line. The Olympic and the Titanic were both White Star Line vessels.

According to Gardiner's theory, the trouble started when the Olympic crashed into a warship in 1911, and was blamed for the accident in an ensuing inquiry. As a result, the White Star Line — an IMM subsidiary — was unable to receive an insurance payout.

Gardiner theorized that the line fixed up the Olympic as best as it could, and masqueraded it as the Titanic. By allowing the wounded ship to continue on under an assumed name, the company could collect the insurance payment when it sunk.

The alleged intent wasn't to kill anyone onboard — if the plan had gone off without a hitch, the ship would have sunk slowly and close to another ship that could subsequently rescue the crew and passengers. So what went wrong? According to Gardiner, the liner ended up accidentally running over a darkened rescue ship, which passengers and crew members would later mistake for an iceberg.

The blog Ultimate Titanic reported that, despite Gardiner's theory, all numbered items pulled from the wreck of the Titanic bore the construction number 401. The Olympic's construction number, on the other hand, was 400.

What's more, "Conspiracies at Sea: Titanic and Lusitania" author J. Kent Layton wrote that, before the Olympic was broken up for scrap, its woodwork was sold. ""Never, not once, as a single piece of woodwork from the Olympic turned up with the number '401' stamped on the reverse," Layton wrote.

This rumor has everything you could want in a conspiracy theory. A man powerful and wealthy enough to play god. Overly-complicated methods of assassination. A mass casualty event. The Federal Reserve Bank.

There's a theory out there that JP Morgan sank the Titanic in order to pave the way for the establishment of the Federal Reserve Bank in the US. The bank's creation was reportedly opposed by millionaire John Jacob Astor, mining magnate Benjamin Guggenheim, and Macy's co-owner Isidor Straus.

These three wealthy men did indeed lose their lives when the Titanic sank.

Astor was last seen clinging to the side of a raft. Guggenheim, whose body was never recovered, reportedly put a rose in his buttonhole and quipped, "We've dressed up in our best and are prepared to go down like gentlemen." And Straus died alongside his wife Ida, who refused to leave her husband's side as the ship sank.

But Morgan dodged death and disaster when he canceled his trip in the eleventh hour. The powerful financier owned the IMM, which in turn owned the White Star Line. As such, he had his own personal suite, promenade deck, and specially-designed bath on the ship.

Morgan was reportedly supposed to be on the ship, but decided to skip the maiden voyage at the last second. The Pittsburgh Post-Gazette reported that he decided to linger in Europe in order to buy tapestries for his art collection.

So what reason would Morgan have to allegedly sink his own ship? Conspiracy theorists say that, in the interest of clearing away opposition to the Federal Reserve Bank, Morgan somehow manipulated all of his rivals into sail on the maiden voyage, so that he could sink it.

But, Layton pointed out that it's almost unimaginable that Morgan could've gotten all three of his major rivals to take the fateful trip.

"Surely there had to be easier ways to carry out the plan?" Layton wrote. "Even more importantly: how was it that no one came forward in the century since and said, 'Yes, I helped to set up the sinking of the Titanic in order to kill three men who were opposed to the formation of the US Federal Reserve'?"
