Sweden has traditionally been part of the European Union’s (EU) pro-enlargement camp and has strongly supported the outlook of a larger Union since becoming a Member in 1995. During its first EU Presidency in 2001 Sweden had EU enlarge-ment as one of its top priorities ahead of the 2004 Big Bang enlargement process. Similarly, in 2009, the country together with Poland took this initiative to the EU’s Eastern Partnership in supporting and more closely integrating the Union’s Eastern Neighbourhood States. Hence, Sweden has traditionally been a firm supporter of a larger EU. Nevertheless, in line with the overall mood within the Union and general ‘enlargement fatigue’, Sweden also took a less ambitious approach in the 2010s and start of the 2020s. However, by contrast in recent years the process has once again gained new momentum.
