They seen question in Northern Ireland and its border is possibly the biggest obstacle in the way of Brexit.

We came here to find out why and to understand the consequences for the people who live here.

For the last century, Northern Ireland has had to wrestle with its identity, torn between Protestants who considered themselves British unionists and Catholics know so identify his Irish nationalists.

The divide by years of conflict in 1968 Catholic minority rose up against union and British control, spurring 30 years of brutal sectarian violence.

Known here's the troubles in 1998.

Both sides compromised under the Good Friday agreement, which created a somewhat unique reality here.

Northern Ireland would continue to be part of the UK, but also open its border completely with the rest of Ireland.

Today, the streets are peaceful, but the history of the troubles is everywhere, and neighborhoods are color coded along sectarian lines here in Londonderry or dairy, depending on us wells like this one separate Protestants from Catholics.

The gate is locked every night for punk band touts.

This us and then mentality has been formed more than just music.

That's amazing.

Are you aware of this sort of division?

Well, it's kind of rough because there's like the book side, which means the conflict area.

Then there's here, which is clearly like the more promising area, but very divided, even though there's trying to do more.

What is that called me like integration or something like that.

They're still trying to get, but their soul of division people told us those divisions have deepened since the Brexit vote.

Under Brexit, Northern Ireland would need with the UK and the Republic of Ireland would mean to you an idea that appears to overlook the reality on the ground.

Here.

We headed east to visit more border communities and actually crossed into the Republic of Ireland multiple times without even realizing it, in part because the border is mostly invisible.

Oh, many of these high school students commute seamlessly from one side to the other to attend school every day.

They worry that Brexit will bring new restrictions.

Anybody asks any strong views on that, like, How would you see yourself in relation to people who live in the north?

If you have a large passport in my mind, you're Irish.

Doesn't matter where your parents from doesn't matter what background you if you carry a large possible you're Irish.

A key part of the Good Friday agreement allows residents of Northern Ireland to choose their citizenship.

British, Irish or both, I think, identify as Irish.

But I mean, I hold a British passport, so really from a identity isn't ever something that in my family was a massive issue.

My parents kind of said you identify it's how you failed him.

I think that that was a really nice way to bring myself.

But depending on how the deal is struck, Brexit could interrupt the free flow of people and goods and possibly violate the Good Friday agreement.

I was actually on decided in the matter.

To the extent that I didn't vote it all on, You don't really want to get involved in the political argument at all bought, Having not said in Northern Ireland, the majority of the vote was in favour off remaining in the U.

That's because many people here remember the border as a source of hostility and violence, and a whole generation since then has grown up without one.

I certainly don't see any need for a hard border just make things harder.

But when Prime Minister Theresa May tried to introduce something called Northern Ireland back start on Northern Ireland backstop the Northern Ireland backstop a provision that would guarantee and exit without a hard border in Northern Ireland, hardline Brexiteers rejected it.

They argued an open border would essentially keep the UK tethered to the U until a viable trading relationship is established.

So no hard border, no deal.

And so far no Brexit.

Also no sense of where this could all lead.

I would be a referendum.

I want to see Ireland reunified.

Well, we've got a doctor, a trauma informed approach and think about everything from the perspective off.
