Berbers were Morocco's first inhabitants, long before Arabs and today they are still the majority, accounting for about 60 percent of Morocco's 30 million citizens. Their culture dates back longer then 4.000 years. They are ethnically mixed and spread over the country, from the Rif mountain range in the north to the Atlas Mountains and the desert in the south. Contrary to the romantic, popular image that portrays Berbers as nomadic people who cross the desert in camels, their main activity is sedentary agriculture, which they carry out in mountains and valleys. The Berber languages are Tamazight, a group of closely related languages mainly spoken in North Africa. Tamazight has been a written language; however, the development of a written Berber language was suppressed by the waves of Arab invasions as Arabic was adopted for all official documents. Many Berbers call themselves some variant of the word Imazighen (singular Amazigh), meaning "free men". Although Imazighen were eventually converted to Islam, their ethnic and linguistic purity has remained. The Amazigh heritage is what makes Morocco and other North African countries unique and different from the Arabs of the near and Middle East. In spite of these hurdles, nothing can stop or even slow down the machine of revival. The Amazigh heart is beating stronger than ever. There is more work to be done at the local and national level, in order to educate and motivate all Imazighen to rise against the cultural discrimination and assert their identity rights.
