The last african colony is a work dedicated to the Saharawis people. They represents a number of nomadic Berber tribes that once moved freely and independently in the Western Sahara. They knew no borders and lived under the power of no government until 1886, the year they were colonized by Spain. Although few people are aware of it, in the desert there is a 2700 Km wall of seven million mines. It was built in 1975 during the “Green March”, which took place when Morocco invaded and militarily occupied the territory of the Western Sahara. Thousands of saharaui were forced to leave their land and seek refuge in the part of the desert to the southwest of Algeria. Those who couldn’t escape had to continue living in the occupied areas under a repressive regime that violated their human rights. For over 37 years the Saharawis are living in exile.
