A potato blight destroyed Ireland's staple crop, and roughly one million people died of starvation and disease while the British government's relief response was slow and limited by laissez-faire policy. Ireland continued exporting grain and livestock to Britain during the worst years of the famine. About a million more people emigrated, and Ireland's population fell by a quarter. economy / society ●●●

September 1845 The Great Famine begins 0 cit. A potato blight arrived in autumn 1845 and destroyed the crop that millions of poor Irish depended on. Because a large share of the rural population relied almost entirely on the potato, repeated failures brought mass starvation and disease. The famine that followed became the defining catastrophe of nineteenth-century Ireland. economy / society ●●●

Pinkerton agents were involved in violent clashes with striking workers, most notoriously the 1892 Homestead strike, where a gun battle between Pinkerton agents and steelworkers left several dead on both sides. The agency's private, unaccountable use of armed force became a recurring source of controversy in American labor history. economy ●●

c. 1850 German-Jewish immigrants found Wall Street houses 0 cit. German-Jewish immigrants founded investment banks in New York, including Goldman Sachs, Lehman Brothers, Kuhn Loeb, and Speyer, often starting as small merchants and dry-goods traders.

c. 1850 The age of caudillos and export economies 0 cit. Through much of the nineteenth century, strongmen known as caudillos dominate politics while new republics tie their economies to exporting a few commodities, from Peruvian guano and Chilean nitrates to Argentine beef and Brazilian coffee and rubber. Dependence on these exports, and on foreign capital and markets, left many countries vulnerable to price swings, a pattern later discussed in debates over the resource curse and dependency. This thread connects to the wider stories on the resource curse and export dependence. economy / politics ●●

c. 1850 The railroads force accounting to grow up 0 cit. Railroads were the first businesses too large and too capital-heavy to run by a merchant's simple cash book. They pioneered ways to account for depreciation of track and rolling stock, to measure cost per ton-mile, and to report to distant shareholders. In his history The Visible Hand, Alfred Chandler argued these accounting tools were what made the modern managed corporation possible. economy / technology ●●●

c. 1850 Indian financiers back the caravans into the interior 0 cit. Banias in Zanzibar advanced goods and credit to the Swahili-Arab caravans that pushed inland to Tabora, Ujiji and the great lakes.

Without Nyamwezi labour and know-how the long-distance traffic in ivory and captives could not have moved. economy / society ●●

c. 1850 Women controlled the food, the farms, and the markets 0 cit. Across the farming societies of Kenya, women did most of the cultivation and controlled the staple food supply, from planting to storage to distribution. Local markets were largely women's ground, where they traded grain, vegetables, and produce and held real economic weight. Control of food gave women leverage over households and communities that men could not easily override. This was practical power, not just labour. economy / society ●●●

c. 1850 Pottery and craft were women's trades 0 cit. Pottery was a women's craft in many communities, including among the Gusii and the Kamba, and skilled potters supplied households across wide areas. Women also made baskets, mats, and other goods that moved through regional trade. These trades gave women their own income and standing, separate from their husbands. The knowledge passed from mother to daughter, keeping the craft and its earnings in women's hands. culture / economy ●●

c. 1850 Women's rights in land and marriage under customary law 0 cit. Under customary systems women held real, if conditional, rights to land through their husbands, fathers, and sons, including guaranteed use of fields to feed their children. Marriage was tied to bridewealth and to obligations that ran both ways, and a wife kept claims of her own within the household. These rights were not ownership in the European sense, but they were secure and recognised. Later land titling in men's names would strip much of this away. economy / society ●●

c. 1850 The mugwe and the blacksmith 1 cit. Alongside the Fathers stood the mugwe, a hereditary ritual dignitary who served for a single generation on the principle "one generation, one mugwe." He blessed warriors and new Fathers with his left hand and, through his enforced passivity, was held to keep the balance between the cycles of rain and sun. Anne-Marie Peatrik pairs him with the blacksmith, an essential but feared outsider bound to marry within his own caste, arguing the system worked by managing the twin dangers of too little and too much distinction. economy / religion / society ●●●

c. 1850 Ogiek honey traded to Maasai and Nandi neighbours 4 cit. The Ogiek exchanged forest honey and hides with pastoralist and farming neighbours such as the Maasai and Nandi, receiving livestock, iron, and grain in return. These same cattle-keepers called the Ogiek il-torrobo, or Dorobo, a term for people without herds. The relationship mixed regular trade with a social ranking that placed foragers below pastoralists. economy / society ●

c. 1850 Iteso organise life around age-classes and mixed farming 0 cit. Iteso society combined crop farming with cattle-keeping and was ordered partly through age-classes and clan ties. Elders held authority in local affairs and ritual. Unlike some neighbours, the Iteso did not build large centralised kingdoms, governing instead through kin and community. economy / society ●

c. 1850 Cattle anchor Kuria economy and status 0 cit. The Kuria combined farming of finger millet, sorghum, sweet potatoes and cowpeas with keeping cattle, sheep, goats and donkeys. Cattle carried deep value as wealth, bridewealth and status, and cattle raiding was woven into their history. Herds remain central to Kuria life and to disputes in the borderland today. economy / society ●

c. 1850 Orma build a cattle economy on the Tana River 3 cit. By the mid-nineteenth century Orma herders had settled in the Tana River country, keeping hardy Boran cattle in a landscape marked by tsetse and seasonal flooding. Milk and cattle sat at the centre of their economy and social life, and they moved herds between wet-season and dry-season grazing. The river and its floodplain were vital for water and pasture. economy / society ●●

c. 1850 Ilchamus fish Lake Baringo from palm-fibre boats 0 cit. The Ilchamus fished Lake Baringo using small rafts and boats made from doum palm, an activity that set them apart from most livestock-keeping Maa neighbours. Fishing, irrigated grain and herding together supported semi-sedentary settlements around the lake. Under Samburu and Maasai influence the balance shifted more toward pastoralism over time. culture / economy ●

c. 1850 Keiyo work two worlds, valley farms and highland herds 0 cit. The Keiyo built a livelihood that moved between the escarpment top and the valley floor. On the highland they kept cattle and grew grain in the wetter climate, while in the hot Kerio Valley they cultivated with the help of irrigation furrows like those of the neighbouring Marakwet. Moving stock and labour between the zones spread risk against drought. economy / environment ●

Prince Albert and Henry Cole organized the first international exhibition of industry and manufactured goods, housed in Joseph Paxton's cast-iron and glass Crystal Palace. Over six million visitors attended in six months, and the fair became the model for the world's fair as a national showcase of industrial power.

15 May 1855 Exposition Universelle of 1855 0 cit. France's first world's fair, staged on the Champs-Élysées under Napoleon III, paired an industrial exhibition with a separate fine arts exhibition, a format later fairs copied.

c. 1855 Cattle raiding and the tribute of fear 0 cit. The Maasai believed their god had given them all cattle, and raiding neighbours for herds was treated as recovery, not theft. Their reach let them tax caravans, demand hongo tribute and hold farming peoples in check. Early European travellers routinely paid to pass and described the Maasai as the terror of the caravan routes. economy / war ●●●
