A language has been considered the one of the most important elements to express the national identity. Therefore the language policy is the political and social issue as well as linguistic issue. In the interchanges among the different cultures through a war or conquest,the ruling countries have been their best to govern the spirit of the colony peoples. They want to control the colony’s language to attain their goals. Namely, they tried to transmit their languages to the colony countries in order to rule their identities. But, the other side, the colony countries had endeavored to keep their language and their identities for the same reason. We can find these phenomena in the new independent Arab countries after the second world war including Algeria. Algeria is the islam country and their mother tongue is the Arabic language since AD 7c. But during the imperial French ruling period(1830-1962), Algeria people had suffered the serious identity confusion because of the massive influx of French. Some of the Algerians insisted that Algeria became the Europe country and the Algerian had to been considered as the Europeans even after independent. I think that this circumstance has deep relation with the language policies that French carried out in the Algeria during their imperial governing. I choose Algeria to research this phenomenon and process and the acceptance of the other language and the related language policies when the languages contacted. To achieve my research goal, I surveyed the sociolinguistic situation in Algeria and the current language varieties, their functions and register. Especially, I researched the process of the acceptance of French language into the Arabic language in Algeria. Ultimately, I expect to see the background and the process of the languages contact and their acceptance of the other language.
