Imagine two countries that had fought wars against each other for hundreds of years. Then one day, they agreed to become a single nation. That is exactly what happened on May 1, 1707. England and Scotland signed the Acts of Union. The deal created a brand-new country called Great Britain. But why did they agree? Scotland's economy was in trouble. A failed colony in Central America had cost Scotland a fortune. Many Scottish leaders believed joining England would bring better trade and more money. England wanted the deal too. English leaders worried that Scotland might pick a different king. That could mean a hostile neighbor right on their border. So both sides had reasons to say yes. The new country got a shared parliament in London. Scotland kept its own courts and churches. Not everyone was happy. Some Scots felt they had lost their freedom. Riots broke out in several Scottish cities. But the union held together. Over time, Great Britain grew into one of the most powerful nations on Earth.
