The first engines were built to pump water out of mines
Deep COAL mines flood. That was the problem Thomas Newcomen's ENGINE solved in 1712, and it was staggeringly inefficient — it cooled and reheated the whole cylinder on every stroke, so it burned enormous quantities of coal. That only made sense at a pit head, where the fuel was underfoot and effectively free.
James Watt's improvement in 1765 was to add a separate condenser so the cylinder could stay hot. Efficiency roughly quadrupled, which meant an engine could earn its keep anywhere, not just on top of a coal seam. Watt did not invent the steam engine, a claim that gets repeated constantly — he made an existing one economic, which is the change that mattered.
The factory is a scheduling invention
Before this, cloth was made at home under the putting-out system: a merchant delivered raw COTTON, families span and wove it in their own cottages at their own pace, and he collected the finished TEXTILE. The MACHINE changed the arithmetic. A SPINNING mule or a powered LOOM was too big and too expensive for a cottage and had to be driven by a water wheel or a steam ENGINE.
So the work moved to where the POWER was, and the workers moved with it. What people found hardest was not the machinery but the clock. A cottage weaver worked long hours but chose them; a MILL ran to a bell, with fines for lateness and no stopping until the shift ended. Factory discipline was a new kind of experience, and it was resisted — the Luddites of 1811–12 were skilled workers breaking machines that had destroyed the value of their training, not people who simply disliked technology.
Canals first, then rails
The Bridgewater CANAL opened in 1761 to move coal into Manchester and roughly halved the price of it, which set off thirty years of canal building. A horse can pull perhaps two tonnes in a cart and around fifty on water, so before locomotives the cheapest way to shift heavy goods was to float them.
The LOCOMOTIVE then made the canals obsolete within a generation. The Liverpool and Manchester line opened in 1830 as the first inter-city passenger railway, and by 1850 Britain had over 6,000 miles of RAILWAY. IRON gave way to STEEL after Henry Bessemer's converter in 1856 cut the cost of making it by roughly eighty per cent, which is what made long bridges, tall buildings and reliable rails possible.
What progress cost, and who paid
Output rose enormously and so did the population. Wages, however, stayed roughly flat for something like the first fifty years while profits climbed — historians call this Engels' pause — so the generation that built it did not see much of the benefit. Life expectancy in Manchester in the 1840s was around 26, against 40 or so in rural Surrey.
The FURNACE, the SMOKE and the endless working day in the grid were the daily reality for a WORKER, including a great many children. Conditions improved through the century by campaigning and legislation rather than automatically, factory act by factory act. The word PROGRESS sits in this word list for a reason, and a class can usefully be asked what it should mean. Our victorians page covers the society this INDUSTRY built.
