We know what Brexit is, but do you really know the whole timeline of it?
Here's a look into what you need to know about Brexit.
And, yes, a lot has changed since 2016, when Brexit was gaining popularity.
Back in July of 2016, Theresa May became the prime minister after a short race due to the fact that her chief rival dropped out of the race.
Flash forward to 2019, when may announced that she would be resigning as the prime minister effective June 7.
But, let's take a look at how we got there.
It goes back to November of 2016 when three high court judges announced that the prime minister does not hold the power to unilaterally trigger Britain's exit from the European Union.
Prior to this ruling, May had been planning a "hard Brexit."
But what does that mean? Britain would leave the EU without a trade deal, which would mean that the country loses its duty-free access to the world's largest trading bloc.
And, keep in mind, Britain's deadline to leave the EU is October 31, 2019. If there isn't a deal struck between the EU and Britain, then Britain would be forced to leave without a deal.
