Imagine that you and your best friend have a really cool toy box that you both love and share. One day, someone else comes along and says that they want to start playing with your toy box too. They keep taking more and more toys from the box, leaving you and your friend with less and less to play with.
This is kind of like what happened in the West Bank. There are two groups of people who live there - the Israelis and the Palestinians. For a long time, the Palestinians had been living in the West Bank and had their own homes and businesses there. But then, the Israelis also started moving in and building their own homes and communities.
This caused a lot of tension and fighting between the two groups because they both wanted to live in the same place and have control over the land. The Israelis say that they have a right to be there because the land is important to them for religious and historical reasons. The Palestinians say that they have a right to be there because it's where they've always lived and they have a strong connection to the land too.
Today, there is still a lot of conflict and disagreement over who should be in charge of the West Bank. Many people believe that a fair solution needs to be found that respects the rights and needs of both groups who live there.
