I have added Single European Act in 1987.
The Timeline is wrong. The European Union didn't start until the Treaty on European Union or Maastricht Treaty came into force in 1992
This chart is rather hard to understand. Some squares are unlabelled, some entities appear twice, and it's unclear what entities merged off of or joined with others vs. what jurisdictions they had. -- Beland 01:21, 28 April 2006 (UTC)
Euratom didn't come into effect until 1957, unlike the chart shows, but I don't know how exactly to change it. 68.40.190.93 00:01, 13 May 2007 (UTC)
The ECSC lasted until 2002 now it looks like it ended in year 2000.Benkeboy 08:23, 19 July 2007 (UTC)

This table badly needs a title bar to explain what it is. My attempts have failed miserably so I've walked away rather than risk ruining it. --Red King (talk) 19:40, 31 March 2008 (UTC)
As somebody introduced the Western European Union I think its' necessary to introduce also the Schengen Agreement! Can somebody do it? Sinigagl (talk) 17:02, 13 April 2008 (UTC)
The recent changes look good, and I think its good the WEU is there, in particular the better grouping of "European Communities". However after that I don't think it makes clear that the other two communities were operated by the EEC - while they were separate, it make it look like they were totally autonomous.- J Logan t: 17:41, 14 April 2008 (UTC)
While it all looks great now, Euratom and ECSC were/are part of the EC pillar,* they may all have their own little area but they are technically all part of the same European Community and this doesn't reflect that. It looks like they are totally detached from the EU and the Community method.- J Logan t: 19:16, 13 July 2008 (UTC)
It took me a long time to figure out that this timeline was not saying that the EU does not exist, and even then I could only figure it out because I knew that to be false. A naive reader would think that the EC was founded some time after the Maastricht Treaty, and that the EU is scheduled to come into being perhaps in 2009. The Czech timeline is much clearer. This really needs to be cleaned up. (In the meantime I labeled the dates of the founding of the EC and EU.) kwami (talk) 11:21, 15 December 2008 (UTC)

I realise it a little squashed but this better reflects the time passed between the treaties. It also gives more emphasis to the EU, so that people like the user above won't say we're trying to say the EU doesn't exist. — Blue-Haired Lawyer 21:34, 27 January 2009 (UTC)
Actually never mind, I withdraw my proposed changes. What we really need is an image. The table is impossible to edit and really limiting. — Blue-Haired Lawyer 20:27, 30 January 2009 (UTC)
Has anyone else noticed how this template looks when it's printed? — Blue-Haired Lawyer 18:50, 8 March 2009 (UTC)

Someone changed the years. The Treaty of Paris (1951) is now listed in the year it came into force (1952). This is irritating. --Kolja21 (talk) 22:33, 14 March 2009 (UTC)
Who told you this? Just read Wikipedia. Header Maastricht Treaty: "This article is about the European Union treaty of 1992." And can't you remember EU celebrates 50th birthday two years ago? --Kolja21 (talk) 00:46, 2 May 2009 (UTC)
First the dates have been changed, now the year 1948 (Treaty of Brussels) was added.[1] What's the benefit of destroying the international version of the timeline? It's troublesome that the English-speaking Wikipedia gets its own EU history, different from all other languages/countries. --Kolja21 (talk) 00:29, 2 May 2009 (UTC)
Wow. Impressive use of WikiMedia tables! --Rebroad (talk) 11:56, 7 July 2009 (UTC)
Hi, Ssolbergj. There are certain things that don't look good with your latest changes:
I'd like to fix the above problems or at least find a reasonable compromise. Any objections? --Informatico (talk) 13:15, 1 January 2010 (UTC)

I guess the real question is: how important the WEU is to the EU and does it really deserve the same amount of space as it given to the European Economic Community? — Blue-Haired Lawyer 22:56, 11 January 2010 (UTC)
Well, we can now let it go away quietly by having its stripe end on 31 March 2010... —Nightstallion 12:11, 1 April 2010 (UTC)
I have updated the chart to correct the first pillar of the Maastricht/Amsterdam/Nice (MAN in the following) EU. The new layout has the following improvements compared to the previous one:

Should we add the Schengen Agreement? It is listed in the Template:EU treaties and declarations. Alinor (talk) 15:44, 28 August 2010 (UTC)

Hi. Can I suggest that the final column on the right be widened? It now covers a period of 5 years, but appears very narrow compared to a similar column, such as the Single European Act (6 years). Maybe the same width as Maastricht? The way it is now, it looks like it hasn't been updated. Just a suggestion! Thanks. 86.163.28.35 (talk) 15:29, 15 April 2012 (UTC)
Article claims the Justice and Home Affairs (JHA) pillar changed to the Police and Judicial Co-operation in Criminal Matters (PJCC) in 2003, however the timeline conversely indicates this happened in 1999. 81.106.49.232 (talk) 23:42, 16 January 2013 (UTC)
