- History
In 1835, Hans Christian Andersen published his first collection of fairy tales (Denmark).
- Media & popular culture
The Sun's 1835 series describing life on the Moon was invented and sold enormously well. No retraction was published, which is an early and instructive case of the commercial incentives around false reporting.

In historical numeral systems
Egyptian
1 lotus, 8 coils of rope, 3 hobbles, 5 strokes
1 × 1,000 + 8 × 100 + 3 × 10 + 5 × 1 = 1,835. 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), 3 corner wedges + 5 vertical wedges (units place)
30 × 60 + 35 = 1835. 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.

Related numbers & connections
1835 is a year in the 19th century, in the 1830s.
The Great Moon Hoax of 1835 was invented and never retracted; the 1938 War of the Worlds broadcast was fiction mistaken for news. Both are studied for what they show about credulity and about newspapers.
