The word Zulu, or Undabezita, was invariably employed in addressing any member of these families, whatever his rank or station might happen to be.
The first king of whom any particulars are known was Senzagacone, son of Ufaina. When this king began to reign he had no legitimate offspring: he had, however, a natural son by Unamdi, daughter of Umkeki, chief of the Langmene tribe, named Chaka (the bastard). He afterwards married this Unamdi, by whom he had a daughter Nuncoba, but no sons. She being his favourite wife, the king, according to the custom of the country, "gave her for a son," his natural son Chaka, thus legitimating him. When Chaka was fifteen, his father, thinking he might become troublesome, sent to kill him; but Chaka, being warned, fled to Dingiswayo, chief of the Umtwetwa, where he remained until the king's death, though on the occasion of his legitimation an invitation was given him to return to the paternal kraal.
Meanwhile Chaka had become an Induna of great influence and popularity in the land of his refuge; so when on the death of Senzagacone the Zulu tribe sent to him requesting him to be their king, and he consented, all the tribes through which he passed on his way to the Zulus accompanied him; and the whole of the Zulu clans assembled to meet him, and he was made king with great rejoicings. In the interim between Senzagacone's death and Chaka's accession, Umkaibye (paternal aunt of Chaka) ruled the Zulus and arranged for Chaka's return. It was now that the jealousy long smouldering between the Umdwandwe and the Umtwetwa, the two most powerful tribes in that part of Africa, broke into an open quarrel. Uzwidi, chief of the former, attacked and utterly routed the latter, killing their chief, Dingiswayo, Chaka's friend and protector. The worsted tribe naturally applied to Chaka for help. Thereupon Uzwidi immediately marched to attack the Zulus, and a great battle ensued on the south of the White Umvolosi. The result was that the left wing of either army was victorious; but both lost so heavily that they retired to their respective countries.
On his retreat, Chaka was attacked by the Langmeni, but failing in their assault, this tribe then deserted their own country and joined the Umdwandwe. Having defeated another coast tribe which assailed him, Chaka occupied both these countries, leaving the Emashlabatini district waste and uninhabited.
Uzwidi had now gathered a fresh army, which Chaka, by a night march, surprised and defeated between Kwagmagwasa and the Umhlatuzi river. He then retreated, but was rapidly followed up by Uzwidi, who had soon regathered his forces, and who succeeded in capturing much Zulu cattle and slaying a number of men, women, and children, surprised in their kraals by the swiftness of his advance. He then again retreated. Uzwidi now made a great and final effort to crush his adversary. All the tribes around were pressed into his service, and the result was that he soon had an army—collected from ten tribes—far superior in point of numbers to the Zulu force, which represented only two tribes. Chaka therefore retreated before Uzwidi's advance, and eventually occupied a strong position on the Inkankla range. Here he awaited his opponent's onset. In place of the old missile weapon, Chaka had armed his men with a shorter and stronger assegai, intended for use at close quarters; he therefore gave them strict orders not to throw their assegais but to charge the foe and fight them hand to hand. He also skilfully placed his force amidst broken ground, so that it was impossible for the enemy to attack in a compact and organized body. The battle, as usual, began in the early morn and continued till after midday. The Zulus, carrying out their leader's instructions, waited till the assault was delivered, and then charged so vigorously on the foe that they swept everything before them. Chaka following up this defeat utterly dissipated the Umdwandwe army. Uzwidi fled beyond his own country, which Chaka annexed, and thus became the chief potentate in that part of Africa, levying tribute from all the tribes around him. Chaka now waged several wars. First he attacked and despoiled the Mangwani, a tribe on the Drakenberg; then he fell upon and extirpated the clan of Zulukanafu, a chief residing to the north of that range. Soon after he sent an army against the Pondos, which captured a considerable amount of cattle and then retreated. Again, in the following year, there was a similar expedition, and the Pondos sued for peace, which was granted. By this time Chaka claimed to rule over the entire country, from the sea to the Pondola, to the Drakenberg, and to the land of the Pondos. His next object was to consolidate his power. Accordingly, the petty kings under his rule were no longer recognized as such, but became tributary chieftains; if any one of these was remiss in payment of his tribute, an "impi" was sent "to eat him" up. From time to time Chaka would also call up these chiefs to his royal kraal, where he would receive them with marks of distinction, and ask their advice on state matters. Another important step to weaken the power of the chiefs, and at the same time to augment his own, was the establishment of a standing army. Military service was made compulsory on all males, each being told off to a certain regiment according to his age. Thus a man ceased to serve under the chief of his own clan, but belonged to a king's regiment, which was composed of men of all tribes. Similar divisions were also made amongst the females, who had to marry into regiments at the king's commands, though on a marriage cattle was still handed over to the bride's father or brother. Furthermore, regiments were not allowed wives till they were entitled to wear "head-rings," and this did not occur till men had reached forty years of age. Chaka's next war was against the Swazis, whom he defeated and made to pay tribute.
In the following year an immense expedition was despatched against the Sotshangana, a people dwelling across the Somba Mountains, beyond Delagoa Bay.
So large was this army that Zululand was almost denuded of warriors, an event which was taken advantage of by Dingaan and five more of the king's brothers, to treacherously fall upon Chaka, whom they slew, together with his chief councillor, Umxamana.
The benefits conferred on his people by Chaka can hardly be over-estimated; he had raised them from a small tribe to a nation, and that nation a dominant one. As the Quirites were amongst the component tribes of the earlier Roman kingdom, so were the Zulus or Undabezita amongst the various tribes subject to the central Zulu authority, and curiously enough this resemblance extends still further; the Quirites were subdivided into gentes, or families, each with a distinctive name, and in a precisely similar manner, as has been before stated, the Undabezita were divided into sub-tribes or clans, each with its own gentile or family name. Nor were his people ungrateful to the memory of their first great king, for after the time of Chaka, the bastard, that name was never employed in its original signification, but to the present day a substitute, "Umlandhwana," is always used by a Zulu to express that idea.
That Chaka was not averse to civilization and white men was evinced by his treatment of Fynn and five others who were rescued from a shipwreck in St. Lucia Bay. He even went so far as to accompany Fynn the whole way to Durban, to see him embark on a ship sent round from Cape Town for him, and to send at considerable expenditure in the shape of cattle two envoys to England, which he contemplated visiting himself, if their report should prove favourable. But this latter project failed in consequence of the king's murder, and the messengers got no further than Cape Town.
A year or two after his departure Fynn returned, and with Chaka's sanction established a trading-station at Durban (1824). Once Fynn and some white men, being called upon for aid, assisted Chaka to punish a refractory tribe. When Chaka's army for the second time invaded the Pondos, it was through Fynn's representations that they would come into collision with the white men that the army proceeded no further.
