In 1967, there was a vote in Gibraltar to decide who the territory would belong to. The people in Gibraltar were asked if they wanted to be part of Spain or part of the United Kingdom.
Think of it like choosing which team to play for in a game of kickball. The people in Gibraltar had to choose whether they wanted to be on Spain's team or the United Kingdom's team.
The vote was called a referendum, which means a vote where everyone gets to have their say. Just like when you and your friends are trying to decide what game to play, everyone gets to share their opinion before you make a decision.
The people in Gibraltar had a very important decision to make, just like how your team's decision can affect the outcome of the game.
In the end, the vote showed that the people of Gibraltar wanted to stay a part of the United Kingdom, which is where they still are today. It's like they chose to stay on the United Kingdom's team for the game of kickball.
This decision was important because it meant that Gibraltar would continue to be its own territory and have its own government, while still being connected to the United Kingdom. It's kind of like how you can be part of your own family but also have friends and belong to your school or community.
