Look for HEMA (Historical European Martial Arts) Clubs, there is also a hemaclub finder (just google it).

HEMA is the entirety of (mostly) medieval and renaiscance "sword" fighting.

Usually longsword but also including Sword and Buckler, Knife/Dagger, Rapier, Gladius, Viking Swords, Axes, Spears, Bow and Crossbows...

Longsword is the most commonly taught weapon, as there are actuall manuscripts, books from the 17th/18th which include instructions on the techniques, the time before that was only erbally taught, from master to students, so we can only guess how they fought.

I can also recommend the youtube channel by "Skallagrim"

Doesn't seen a good idea if you don't know what sword names there are for a start. There are a large variety but you maybe thinking of rapiers or small swords or sabers but maybe you mean hangers or Olympic style fencing. Never heard of dueling swords. You want to teach after watching YouTube?

I wouldn't want to learn from someone who learn't a dangerous sport off YT.

Swords are pretty expensive and there is a lot of safety gear of course.

You could try googling hema schools if you want historical.
