Since you're all about sea shanties these days, WHO WANTS TO HEAR ABOUT GAY MARRIAGE IN THE GOLDEN AGE OF PIRACY?
Now, a lot of what we're about to tell you is the subject of debate, because history, when written down, tends to elide homosexuality. Therefore, there's nothing in history which outright says "these pirates were hella gay and marrying each other all across the high seas".
So, among pirate communities during the golden age of piracy, there was an arrangement called "matelotage". Crew members could form a bond together where one would inherit the other's wealth - rather like a marriage.
Now, some say that matelotage was a strictly economic arrangement for division of assets, but tbh, that's what a conventional marriage is, so.
There was definitely passion involved in some matelotages - for example, when Captain Bartholomew Roberts stabbed a crewman for being rude to him, the dead man's matelot got VERY angry, confronted his captain furiously... and Roberts stabbed him, too. Then had him beaten.
