Nowadays, English is one of the most spoken languages in the world not only by its popularity but also by its evolution through the years. English is a Germanic language that has an interesting history full of battles and periods of time which permanently marked the development of English trough time. There are five main periods in the history of English that tell us how this 

Sá de aa in what now is England and how it has evolved over the years.

The first Indo-European speakers to arrive to this country known today as England were the Celts that the historians does not have an specific date about their arrival, but they assure they were already on the British Isles several centuries before the birth of Christ. In 55 BC, Julius Caesar who was the Roman Emperor tried several times to invade British; although, it was not possible until 55 AD that this place was under Roman domination. In 410 after Christ Roman legions came back to Rome, so the Jutes and Saxons attacked the eastern coasts and the Britons were driven back into mountain areas of Cumbrias.  As a result, Wales Germanic speaking tribes replaced the Celtic people.

The second period called the old English occurred between 600-1100 AD. This started when Germanic tribes (the Saxons, the Angles and the Jutes invaded Britain. The old English period is characterized by the strong linguistic influence of the Germanic, Saxon and Jutes tribes since their invasion allowed that a combination of diverse dialects will create a new language which is used to refer to the language now called Old English, spoken and written by the Anglo-Saxons and their descendants in this country now known as England and the southeastern part of Scotland.

The third period known as the Middle English begun with the battle of Hasting in 1066, that was a key event in the Norman conquest of England because William Duke of Normandy who was known as William Conqueror after the battle, defeated the king Harold II in October of the same year. As a king William decided to make political and social changes that affected enormously the English language. As a result, all these events made that English lost its status and became the language of the lower classes.  In 1204 the King John Lackland lost his English possession in France because of, this English was replaced by French as the official language in England, but there were important events the sealed its fate, the Black Death, the Hundred Years War, the introduction of painting press and the discovery of America in 1492, This latter marked the end of the Middle English.

         The fourth period called the Early Modern Language, during these years occurred diverse events that influenced the language.  Firstly, we have two events that sealed its destiny, the Hundred Years War between 1337-1453 and the Black Death in 1337 which killed one third of population in five years. Secondly, we have two incidents that had an enormous impact on the development of English, the introduction of the printing press to England in 1476 by William Caxton and the discovery of America in 1492. Thirdly we have the ascendancy of Henri VIII in 1509 who eventually cut the links to Rome and the Catholic church. Then we have one of the most important event in that era. Finally, the Great Vowel Shift since the language suffered radical changes, the works of William Shakespeare and the beginning of the scientific age around 1700.

Lastly, the beginning of the present day English started by the end on the reign of Elizabeth I in 1603 who was the daughter of Henri VIII. In this later period literature had boomed trough the works of Marlowe of Spencer, William Shakespeare, Francis Drake and Walter Raleigh. Their works had laid the foundation for expanding the English influences in the new world. The worldwide spread of this language consist in terms of three concentric circles. Firstly, the Inner circle which refers to traditional, historical and social linguistic origins of English where it is used as a first or native language. Secondly, the Outer circle includes countries colonized by Britain and United States where English is spoken as a second language and where it plays important historical, and    governmental role in multilingual settings. In the last one called Expanded circle was not institutionalize English as an official language, but recognized the important of it as a foreign language.

In conclusion, the English language has a complex history full of episodes that allowed the establishment of a language with particular linguistic characteristics. English evolution consisted in five main periods which we discovered that little by little was losing influence in the Middle English and was almost removed by the arrival of French language; although, the English did not disappear and regained its strength with the explosion of literature which allowed its spread. All these events explain its development trough the centuries and why is one most important languages in the world since it is spoken around 1.5 billions of people.
