Where 1811 fits
Why 1811 is special
Textile workers destroyed machinery that was being used to bypass skilled labour and drive down wages. They were not opposed to machines as such, which is precisely the opposite of what the word now means.
Same number, different meanings

- History
In 1811, Luddites began breaking textile machinery in Nottinghamshire, in protest at the terms of mechanisation rather than at machines as such (England).
- Finance & economics
The Luddites targeted machinery used to undercut skilled wages, not technology in general, and negotiated where they could. Calling someone a Luddite today inverts the movement's actual position on machines.

Egyptian
1 lotus, 8 coils of rope, 1 hobble, 1 stroke
1 × 1,000 + 8 × 100 + 1 × 10 + 1 × 1 = 1,811. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges (sixties place), 1 corner wedge + 1 vertical wedge (units place)
30 × 60 + 11 = 1811. Places are separated by a space on the tablet, with the higher place written first.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
