"Not long after he had built a magnificent palace and built schools for his people, the French took control of Cameroon. Their power was threatened by his achievements. They destroyed the printing press that he [King Njoya] invented, destroyed his libraries, and burned many of the books he had written. The French soldiers threw Bamum sacred objects into the street. And finally, in 1931, they sent him into exile in the capital of Yaoundé where he died a broken man in 1933. Over the years, Njoya’s son and heir Seidou Njimoluh quietly worked to preserve his heritage."
