Berlin

Berlin (, ) is the capital of Germany and one of the 16 states of Germany. With a population of 3.5 million people, it is the second most populous city proper and the seventh most populous urban area in the European Union. Located in northeastern Germany on the banks of Rivers Spree and Havel, it is the centre of the Berlin-Brandenburg Metropolitan Region, which has about six million residents from over 180 nations. Due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. Around one-third of the city's area is composed of forests, parks, gardens, rivers and lakes.

Berlín is a municipality in the Usulután department of El Salvador.

The Berlin Plus agreement is the short title of a comprehensive package of agreements made between NATO and the EU on 16 December 2002. These agreements were based on conclusions of NATO's 1999 Washington summit, sometimes referred to as the CJTF mechanism, and allowed the EU to draw on some of NATO's military assets in its own peacekeeping operations.
