Other African groups, including the
Hehe (the second to imitate the Ngoni), they took Sangu regimental names and language forms. The father of
Chief Mkwawa of the Muyinga family of the Hehe people began to form a unified state to be called Uhehe. The Hehe people attacked the Sangu in 1857 and forced them to abandon their capital
Utengule at least three times. The Sangu repeatedly attempted to return to Utengule but failed. They retreated westwards to build a new Utengule near present-day
Mbeya. This location which was to become one of East Africa's most elaborate
Bomas (a massive stone fortress, supposedly the largest in East Africa, later deliberately destroyed by the Germans). The Hehe, recovering from their own civil war in 1879, continued their aggressive expansion and showed themselves to be more than a match for
Merere II, the Sangu leader, despite the fact that the Sangu had reportedly begun using guns as early as 1893, had great experience in war and were noted for 'throwing their dead away' mostly into ravines. All Sangu chiefs carried the title of Merere, whose personal name was Mwahavange, the title-holder. Sangu, Bena and Kinga are part of the Niger-Congo-Bantu people who lived in Iringa province before ivory and slave hunters Ngazija (Shia Iranian) from Comoro came. The Ngazija Iranian people are part of the family of Mnyigumba Muyinga, the father of Chief Mkwawa. Their hunters used Hamitic People from Ethiopia as their guide to hunt and kill elephants and the Bantu people were used to carry ivory to the ocean by Zanzibar. Now referred to as Sangu, many ran away and hid in areas such as Usangu Basin to avoid being enslaved. Others went to the Ukinga Maountan, and are now known as the Kinga Peoples. The people who hid in the Bena Caves now are known as Wabena Manga, and those who went to Pangwa Mountain are called the Wapangwa people, etc. Mnyigumba forced the Bantu people (now Hehe) to adopt their culture and religion. The scarves and turbans they wear are similar to Iranian dress. ==German involvement==
