They said, "Let's go," shocking the entire world.

No country has ever left the 28-nation European Union ... until now. On Thursday, June 23, the United Kingdom voted to separate from the EU -- sending financial markets reeling, up-ending a world power's leadership and triggering a wave of emotion across Europe.

This is how the dramatic decision unfolded, how you're affected and what happens now:

THE FINAL RESULTS

Hold up ...

Not everyone wants to leave. The majority in Scotland voted to stay. It will now hold its own referendum to leave the UK and remain with the EU. ​ The map tells a very big story

THE DRAMA

Is Boris next?

Former London Mayor Boris Johnson, who campaigned hard to leave the EU, is Davd Cameron's likely successor as prime minister. Johnson was greeted by a booing crowd the morning after the vote.

THE PLUMMET

As the vote swung toward "leave," the British pound dropped to its lowest level in more than 30 years.

Meanwhile it was a dark day for the market as tumbling stocks hit Europe, Asia, London and Wall Street.

THE MONEY QUESTIONS YOU'RE ASKING

Is this 2008 all over again? Although investors across the world Although investors across the world went into panic mode as stocks tumbled, experts urged everyone to keep calm. "This may be more of a political crisis than a financial crisis. That makes this different from Lehman Brothers going under in 2008," Chris Gaffney, president of EverBank World Markets, told CNN Money. "It does not look like this is a liquidity crisis. But it's a big deal."

What about jobs? Leaving the EU could put many jobs at risk . Many American and global banks and companies have invested heavily in the UK as a gateway to Europe. Some companies could relocate staff to avoid obstacles in business.

The UK will probably see fewer tourists from the EU, which made up seven of the top 10 countries that visited last year. But don't even get us started on those longer lines at immigration...

But what if I am a British traveler? You can most likely breathe a sigh of relief. Because Britain isn't part of Europe's borderless Schengen zone, you're already checked at entrance points in EU-member nations. You can show your passport, but you won't need a stamp to enter. This probably won't change even after Brexit.

WHAT'S NEXT
