The Zulu chief Dingane came to power by assinating the founder of the zulu nation Shaka. Dingane lacked Shaka’s military and leadership skills however and the cracks in the kingdom began to show as rebel chiefs broke away. These cracks were exacerbated by armed conflict with the newly arrived Voortrekkers. He ambushed and killed about 500 Boers in 1838. In revenge the forces of Andries Pretorius killed about 3,000 Zulus in the Battle of Blood River. Subsequent Boer intervention in Zulu domestic affairs led in 1840 to the overthrow of Dingane and the crowning of Mpande his half-brother.
