What if a Norse settlement endured in North America?
Archaeological remains at L’Anse aux Meadows establish a Norse presence in North America around 1000 AD. They do not establish the lasting colony imagined here. Changed assumption: A Norse settlement secures reliable supplies and peaceful exchange with neighbouring Indigenous communities, allowing it to endure for several generations. Possible consequences (counterfactual): First generation: supplying food and repairing ships become decisive constraints. Next generation: continued exchange depends on choices made by Indigenous communities as well as the newcomers. Longer term: a durable route could change movement and trade; wider political outcomes remain uncertain.
What if Roman rule in Britain continued?
Roman government in Britain ended amid political and military change in the early fifth century. Continued rule is the changed assumption in this example. Changed assumption: The western imperial government retains enough military and fiscal support to sustain its administration in Britain for another generation. Possible consequences (counterfactual): Immediate: maintaining troops requires money, food and political support. One generation later: towns and local elites may retain stronger institutional links with the empire. Longer term: survival in Britain would not by itself resolve the wider empire’s difficulties.
What if the Black Death had been less severe?
The Black Death caused catastrophic loss of life and major social disruption. The lower mortality assumed here is a counterfactual, not a historical claim. Changed assumption: The first pandemic wave causes substantially lower mortality, changing the labour and political pressures that follow. Possible consequences (counterfactual): Immediate: more households and farms retain their workers. Following decades: labour bargaining power may develop differently, with regional variation. Longer term: wages, institutions and cultural change still depend on many other causes.
What if a Maya city expanded its water storage?
Classic Maya centres used managed water systems. This is an imagined decision in a representative city, not a claim that one intervention would prevent wider political change. Changed assumption: The city invests earlier in additional reservoirs and maintained drainage, changing its resilience during a period of water stress. Possible consequences (counterfactual): Immediate: construction and maintenance require labour and resources. During water stress: additional storage may help, depending on rainfall, capacity and water quality. Longer term: political relationships and environmental pressures still influence the city’s future.
What if Elizabeth named a successor earlier?
Elizabeth died in 1603 without a child of her own; James VI inherited the English crown. Changed assumption: Elizabeth publicly names James VI as successor several years before her death. Possible consequences (counterfactual): Immediate: advisers seek guarantees about the succession. Following years: the named heir could become a rival focus of political influence. Longer term: survival and political support still determine whether the succession holds.
What if Ibn Battuta returned home earlier?
His travel account describes leaving Tangier for pilgrimage in 1325 and journeys far beyond it. Changed assumption: Ibn Battuta returns to Morocco after his first pilgrimage instead of extending his journeys. Possible consequences (counterfactual): Immediate: he follows the route home. Following years: different professional and personal opportunities shape his life. Longer term: a later narrative contains fewer journeys; existing trade networks continue.
What if Napoleon won at Waterloo?
Wellington’s allied force and Blücher’s Prussians defeated Napoleon at Waterloo. Changed assumption: Prussian intervention is delayed long enough for Napoleon to defeat Wellington’s army. Possible consequences (counterfactual): Immediate: casualties and exhaustion limit pursuit. Following weeks: coalition forces regroup while Napoleon chooses his next move. Longer term: a battle victory may improve negotiating prospects but does not end the wider war.
What if Japan negotiated a different settlement?
The Meiji Restoration restored imperial rule in 1868 amid domestic and foreign pressures. Changed assumption: A compromise retains a significant governing role for former shogunate leaders while accepting reforms. Possible consequences (counterfactual): Immediate: offices and military authority are shared differently. Following years: reform and taxation become contested decisions. Longer term: the compromise survives only if competing groups keep cooperating.
What if a second witness account survived?
Percy’s historical report is a source for the Tarrare story. Its existence does not confirm every later retelling. Changed assumption: A fictional archivist discovers an independently dated witness account relevant to one claim in Percy’s narrative. Possible consequences (counterfactual): Immediate: the archivist checks the document’s provenance. Next: its claims are compared with the older report. Longer term: confidence in one claim may change while other questions remain unresolved.
What if the Armada landed an army?
The planned invasion of England in 1588 failed. A successful landing is the changed assumption. Changed assumption: The Spanish fleet achieves the coordination needed to land an invasion force in England. Possible consequences (counterfactual): Immediate: commanders need supplies and a secure landing area. Following weeks: resistance and political choices shape the campaign. Longer term: a landing does not guarantee durable rule or uniform religious change.
What if crop protection came first?
The Emu War was a military-assisted wildlife-control operation that did not resolve the problem as intended. Changed assumption: Authorities prioritise crop protection and coordinated local planning before military intervention. Possible consequences (counterfactual): Immediate: funding and responsibility must be agreed. Next season: maintenance and wildlife movement affect results. Longer term: policy is judged by crop damage and costs, not a military victory metaphor.
What if coordination broke down in 1919?
May 1919 was a crucial phase in a longer conflict and political transformation ending in the 1923 settlement and republic. Changed assumption: Communications between nationalist organisers fail for several critical weeks. Possible consequences (counterfactual): Immediate: local groups struggle to agree on aims and leadership. Following months: mobilisation may slow or rival centres may emerge. Longer term: diplomatic and military outcomes depend on decisions by many actors.
