Scots headed to the polls on Thursday to take part in a historic referendum on whether to end more than 300 years of union with England.
At polling booths around the nation, 4.3 million voters have the chance to answer "yes' or "no" to the deceivingly simple question: "Should Scotland be an independent country?"
Opinion polls show opponents of independence are just a few percentage points ahead, suggesting that the vote will be a very close contest.
On Wednesday, both sides made a last ditch appeal to voters. Scottish nationalist leader Alex Salmond said Scots would seize "a once-in-a-lifetime opportunity to take the future of this country into our hands." Meanwhile, former U.K. Prime Minister and Scot Gordon Brown urged Scotland to consider whether it wanted to "break and sever every link," with the rest of the country.
