Modern history begins in 1817, when Karl Drais invented his ‘running machine’
Actually that seriously would be year 1 of quite a significant modern common era – year zero would the ‘Year without a Summer’ which was 1816. The driving force behind what became the bicycle was in part the global famine that resulted from a volcanic eruption that year. Crop failures meant amongst other things there was no oats for horse feed and that drove the development of mechanical means of transport.
At this time of year theres quite a signfifcant echo of that event in the way we decorate our houses at christmas, all around the world, to look like the Christmases Charles Dickens remembers from his childhood in the 1810s. Even though it rarely snows at chairmas in the UK we much of our Christmas imagery is snowy – even Australian Christmas cards have snow on them.
We still have quite a lot of cultural echos from that year
You can even date artwork by the use of certain pigments in becuase sunsets looked different before and after 1816
