A bit about Minhagim (particularly in relation to the terms Sephardic, Ashkenazi, Yemmeni, Mizrahi, Beta Yisrael, etc.)
I saw this post, and I realized that what I take for granted knowledge wise may not be so, and people rarely talk about the intricacies of Minhagim.
(btw, what I am saying applies to all the different groups but for the rest of the post I'll be mainly using the Sephardic and Ashkenazi b.c. I am lazy)
We use the terms "Ashkenazi" and "Sefardic" (etc.) to refer to where our ancestors came from (or more likely lived in 1500s or so), which is fine! But that not 100% accurate. Or at least it would be more accurate to say that that is a secondary meaning that is used a lot, but there is a primary meaning which can get confusing.
The primary meaning of these terms is "Which bundle of Minhagim do you follow?"
Now seeing as minhagim are traditions that carry the weight of a law, usually it is your ancestry, but not always!
We will take 2 obvious cases first, then talk about some other ones:
First Someone who converted. Now obviously since they converted they have no (halachically) relevant Jewish traditions. So what do they take? One might be tempted to say "whatever area their ancestors were from" but honestly that makes no sense. They don't have a tradition from those people, just geographical happenstance.
Rather they are to take on the traditions of the community/location where they converted. So a Polish person might become Sephardic, or a Italian person Ashkenazi.
The Second is marriage. When people get married (with some exceptions) the wife is supposed to take on the husbands traditions (don't @ me, we can discuss gender in Judaism another year). So, a Ashkenazi woman who marries a Sephardic man is now Sephardic (though they would usually say that they follow Sephardic customs to avoid confusion).
And it is worth noting that many people keep their exes traditions even after getting divorced.
Now to some more interesting ones:
A Jew who was raised not religious in any way has no tradition! So if they become religious later in life, they can take on any minhag they desire. Usually they do end up taking their ancestral one, or the one of the community they live in, but there is no need! (lpt for those becoming religious: 1 hour between meat and milk is a valid minhag that you can take!)
And finally: Moving. If a Ashkanzi Jew moves to a purely Sephardi area, they are obligated to take on Sephardic customs! This is actually the big one, all the others kinda fall from it, but on the other hand it is basically not applicable anymore.
Way back when, when travel was a big deal, you would probably be the only Sephardi in Poland, so you couldn't really keep it.
Nowadays that basically everywhere is uber multicultural that ruling isn't applicable, but still interesting!
N.B. Not my best write up, I may redo it completely later
