Gothic used to be widely spoken in Eastern and Northern Europe in 3 AD. Today, Gothic is an extinct language as is its entire language family, East Germanic. The reason for the Gothic language dying off is because descendants of Goths were converted to other languages through process of political dominance and cultural preference. After Christianity became popular, for example, many people switched from the Gothic language to Roman. The history behind this language just goes to show why we put so much effort into preserving languages. As the world becomes more globalized, it is easy for certain languages to become less popular and eventually die out, however we need to save these languages because they are an important part of local diversity.

Hebrew used to be a very widespread language in biblical times but eventually it started fading off and becoming endangered. In 4 BC, the language was often only used for Jewish church services. In 1948, Israel was established as an independent country and made Hebrew one of its official languages. This is because there was a large Jewish population in the area. Along with Hebrew, Arabic is another official language. Since the Jews and Muslims were the two distinct cultural groups in Israel, they both wanted their own language to represent them. This is why the Jews in Israel put effort towards reviving the language.

The Celtic language branch is an Indo-European branch and was a major language in the British Isles and the Northwestern coast of Europe for ages. Before, there were Celtic languages spread across many parts of Europe, however now they are limited to only remote parts of England, Ireland, Wales, and the French peninsula. Later, the Germanic Angles, Jutes, and Saxons invaded the British Isles and people fled to Wales or Cornwall, or they crossed the English Channel to parts of France. Many Celtic languages, such as Cornish became extinct. The Celtic languages declined because they lost most of the territory to speakers of other languages. People of the British Isles had to start learning other languages, such as English so that they could compete for jobs.People are now putting forth effort to preserve Celtic languages. For example, Welsh is one of the languages in danger. Local governments and utility companies are now obliged to provide service in Welsh and Welsh history and music have been added to the curriculum of schools. Irish Gaelic is also making a comeback as bands have started to record music in this language. There is also a TV channel that is completely in Irish Gaelic. This effort is mainly being put forth by young Irish who wish to distinguish themselves from the English and preserve their local diversity.
