The Great culling (1856-1858) and aftermath

Sarili played an important part in the Great Cattle Killing, a millennialist movement which began among the Xhosa in 1856, and led them to destroy their own means of subsistence in the belief that it would bring about salvation by supernatural spirits, who would return and drive all white people into the sea. Genuinely believing the prophecies of Nongqawuse, Sarili destroyed his cattle and crops, causing thousands of his subjects to do likewise. The famine that followed devastated the last Xhosa Kingdom, forcing the Xhosa to turn to the neighbouring Cape Colony for food, blankets and other relief. His fostering of the cattle killing also led to him being hated in white opinion, as the supposed villain of the frontier conflicts. He was briefly exiled from Gcalekaland, to the territory on the far side of the Mbashe, only being allowed to return in 1865. In his absence, the Mfengu people (traditional enemies of the Gcaleka) settled in much of his former land.^[2]: 688

The Fengu-Gcaleka War (1877-1879)

Subsequently, the policies of the Cape Colony and those of the government in London differed with regards to Sarili. The Cape achieved responsible government in 1872 and, with little further interest in annexing Xhosa land, signed treaties with both Sarili and his enemies such as the Thembu, recognising Gcalekaland's territorial integrity. The British government, on the other hand, sought to offer protection to increasing numbers of Transkeian chiefdoms, isolating Sarili diplomatically and reducing his power in the region. Both parties appear to have favoured Sarili's enemies in trade and other dealings with the Transkei territories, and when fighting broke out between Sarili and the neighbouring Thembu, the British government intervened once again and brought yet another of his opponents under their protection.

From the mid-1870s, a series of severe droughts across the Transkei began to place growing strain on the relative peace which had prevailed for the previous few decades. The droughts had begun as early as 1875 in Sarhili's territory, and had spread to other parts of the Transkei and Basutoland, and even into the Cape Colony controlled Ciskei. Their severity increased up until 1877 and ethnic tensions began to break out, particularly between the Mfengu, the Thembu and the Gcaleka Xhosa.^[3][4][5]

In 1877, fighting between Mfengu and Gcaleka tribesmen broke out at a festival, rapidly escalating into a shoot-out and finally into a full-blown inter-tribal war that spread along the frontier. Sarili sought to avoid any further escalation of this conflict, as he fully understood that the Mfengu, as allies of the Cape Colony, would draw all forces stationed in the Cape which he could not overcome. However he was nonetheless forced into involvement by several of his councillors and chiefs. Decades of hostile relations with the Cape Colony, overpopulation, and pressure from his councillors drove Sarili into a corner, and he mobilised his armies. Initially the situation seemed unlikely to escalate further, as the Cape Colony government insisted on only deploying its local mounted commandos to police the frontier, but the involvement of the British government, via Sir Sir Henry Bartle Frere, desiring to finally annex Gcalekaland for his planned confederation of South Africa.

Sarili tried to unite the Xhosa tribes into a unified force in order to prevent the annexation, but after two devastating pitched battles, he declared an end to his resistance and went into exile, first in Pondoland and afterwards to Bomvanaland.

He died in exile in 1892, at Sholora, Bomvanaland.^[6]
