Why is the country Germany named Germany?

The name "Germany" is derived from the Latin name Germania, which was first used by the Romans in the 1st century BCE to refer to the region east of the Rhine and north of the Danube rivers. The name is thought to be derived from the Celtic word germanos, meaning "neighbour" or "brother".

The name Germania was first used in English in the 16th century, and it gradually came to be used to refer to the entire region of Central Europe that is now known as Germany. The official name of the country is the Federal Republic of Germany (Bundesrepublik Deutschland).
