Politicians in Northern Ireland, who have disagreed with each other for years, have decided to work together.
This means that from 8 May, decisions on things like education will be made by the Northern Ireland Assembly instead of the British government.
It's a big step because until now the two main parties called the DUP and Sinn Fein have disagreed so much that they've been unable to work together.
One of the first issues the Assembly will look at is the 11 plus exam.
This is a test that kids in Northern Ireland take which decides which secondary school they go to.
Prime Minister Tony Blair said the decision to share power was very important for the people of Northern Ireland.
