Source-derived summary

The history of the European Union from 2004 to the present is the current timeline of the European Union. It is a period of significant upheaval and reform following the 2004 enlargement of the European Union. The EU has taken on ten new members, eight of which were initially much poorer than the EU average, and took in a further two in 2007 with many more on the way. It created the euro a few years before and had to expand this, and the Schengen Area to its new members. However this was overshadowed by the late-2000s recession and damaging disputes over the European Constitution and its successor, the Treaty of Lisbon. Throughout this period, the European People's Party has been the largest group in the European Parliament and provides every President of the European Commission.

Parliament and Commission

During 10–13 June 2004, the 25 member states participated in the largest trans-national election in history (with the second largest democratic electorate in the world). The result of the sixth Parliamentary election was a second victory for the European People's Party-European Democrats group. It also saw the lowest voter turnout of 45.5%, the second time it had fallen below 50%.

Barroso I

The Prodi Commission was due to end its mandate at the end of October 2004, so following the 2004 elections to the Sixth European Parliament, candidates for Commission President began to be considered.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “History of the European Union (2004–present)”, the useful work is to connect “aspect of history” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 27, 2026. The linked authority identifier is Q5869413. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2004 and 2007.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
