Where 1968 fits
Why 1968 is special
Protest movements, assassinations and strikes ran through the United States, France, Czechoslovakia, Mexico and elsewhere within months of each other. As with 1848 the events had different local causes, and treating them as one movement is a retrospective framing rather than something the participants shared.

In historical numeral systems
Egyptian
1 lotus, 9 coils of rope, 6 hobbles, 8 strokes
1 × 1,000 + 9 × 100 + 6 × 10 + 8 × 1 = 1,968. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 2 vertical wedges (sixties place), 4 corner wedges + 8 vertical wedges (units place)
32 × 60 + 48 = 1968. 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.
