The year 1989 marked a big change in Europe, leading to the creation of the European Union and the addition of new member countries. This shift allowed for the development of a Common Foreign and Security Policy. By the early 1990s, the European Commission had a plan to bring in more countries, resulting in ten new members joining in 2004 and two more in 2007. The impact of 1989 on European integration was significant, shaping the future of the Union.
