The 14 Points were a set of ideas and goals put forward by American President Woodrow Wilson during World War I (1914-1918). The idea behind the 14 points was to create a plan that would shape a lasting peace, and help to prevent future wars.
The points were divided into two sections - the first four dealt with creating a safe, fair and free world, including outlining how countries should act properly and peacefully. The rest of the points outlined how to divide up Europe to end the war, and included ideas about how to stop future wars (e.g. by creating an international body to stop countries fighting against each other).
The 14 Points helped to create the peace agreement that ended WWI and laid the groundwork for the modern world. Basically, they tried to make it so that other countries and their own wouldn't end up fighting each other again in the future.
